This paper introduces two types of power cables: Duplex N2xoh XLPE 1kV 3X1X120mm² cable and Nyy PVC triple three-core copper cable (specification 8.89). Both are suitable for low-voltage distribution systems but differ in materials and characteristics.​ The Duplex N2xoh XLPE cable uses cross-linked polyethylene (XLPE) insulation with a rated voltage of 1kV. Its structure consists of 3 groups of single-core 120mm² conductors, and the "Duplex" label indicates its dual-group parallel design, suitable for scenarios requiring multi-circuit power supply. The XLPE insulation layer has strong temperature resistance (long-term 90℃) and stable insulation performance. Moreover, the halogen-free and environmentally friendly material produces low toxicity and low smoke when burned, making it ideal for industrial areas, high-rise buildings, etc., with high safety requirements.​ The Nyy PVC triple three-core copper cable uses polyvinyl chloride (PVC) for insulation and sheath, with high-purity copper as the conductor. The specification 8.89 corresponds to specific structural dimensions. PVC material has low cost, good corrosion resistance and mechanical strength, suitable for general commercial buildings, civil distribution and other scenarios with moderate environmental protection requirements. The three-core design is compatible with three-phase circuits, enabling convenient installation.​ Both cables ensure conduction efficiency through copper conductors. The former emphasizes safety, environmental protection and high-temperature stability, while the latter highlights economy and versatility, providing targeted solutions for different power distribution needs.

Copper core PVC insulation flat cables, available at factory prices, are specialized electrical cables designed for maritime and shipping applications, where reliability, space efficiency, and resistance to harsh environments are paramount. These flat-shaped cables feature high-purity copper conductors, PVC insulation, and a compact, flattened profile, making them ideal for integrating into the tight, vibration-prone spaces of ships, offshore platforms, and port infrastructure. Engineered to withstand saltwater corrosion, extreme temperatures, and mechanical stress, they ensure consistent power and signal transmission for critical shipboard systems, from navigation equipment to lighting and machinery. At the core of these cables are high-purity copper conductors, typically stranded to enhance flexibility—essential for navigating the confined spaces of ship hulls, engine rooms, and control panels. The copper, with a purity of 99.9% or higher, delivers exceptional electrical conductivity (≥97% IACS), minimizing energy loss even over long runs (up to 100m) common in large vessels. Stranded conductors (composed of 19–41 fine strands, depending on size) also resist fatigue from constant vibration, a key challenge in marine environments where engines and waves generate persistent movement. Conductor sizes range from 1.5mm² (for low-power systems like communication devices) to 10mm² (for heavy-duty applications such as pump controls or propulsion systems), with current-carrying capacities from 10A to 50A, ensuring compatibility with diverse shipboard electrical demands. Each copper conductor is insulated with marine-grade PVC, a material selected for its resistance to saltwater, oils, and UV radiation—hallmarks of the maritime environment. The PVC insulation operates reliably within a temperature range of -20°C to 70°C, with short-term tolerance up to 105°C during overloads, making it suitable for both cold polar voyages and tropical climates. It provides robust dielectric strength (≥15kV/mm) to prevent short circuits, even in humid or condensation-prone areas like bilges or cargo holds. Additionally, the PVC is flame-retardant (meeting UL 94 V-0 standards), a critical safety feature in enclosed ship spaces where fire risks are amplified by limited ventilation. The flat design of these cables is a defining advantage for shipping applications. Unlike round cables, their flattened profile (typically 8mm–20mm wide and 3mm–8mm thick) allows for easy installation in tight gaps between bulkheads, under floorboards, or alongside pipes—maximizing space efficiency in crowded ship compartments. This design also reduces the risk of snagging or tangling, which is crucial for maintaining safety in high-traffic areas like engine rooms. The flat shape simplifies bundling and routing, enabling neat, organized wiring that eases maintenance and inspection—essential for complying with maritime regulations (e.g., IMO SOLAS). Factory pricing for these cables makes them cost-effective for large-scale maritime projects, such as new ship construction or fleet retrofits. By sourcing directly from manufacturers, buyers benefit from reduced costs without compromising quality, as factory production ensures adherence to strict standards like IEC 60092 (Marine Electrical Installations) and ABS (American Bureau of Shipping) certifications. These standards validate the cables’ resistance to corrosion, flame spread, and mechanical impact—critical for ensuring seaworthiness and passenger safety. Applications in shipping are diverse and safety-critical: Navigation and Communication: 1.5mm²–2.5mm² cables power GPS systems, radar, and radio equipment, with stranded conductors ensuring signal stability amid vibration. Engine Room Systems: 4mm²–6mm² cables connect pumps, generators, and fuel controls, where PVC insulation resists oil and coolant exposure. Lighting and Habitation: 2.5mm² cables supply cabin lighting, HVAC, and galley appliances, with flame-retardant PVC reducing fire risks in passenger areas. Cargo Handling: 6mm²–10mm² cables operate cranes and winches, with robust copper cores handling high currents and flat profiles fitting into machinery housings. Installation benefits include compatibility with standard marine terminals and cable clips, as well as easy stripping of PVC insulation for secure terminations. The cables’ flexibility allows for bending around structural obstacles without kinking, a key advantage when retrofitting older vessels. Additionally, their resistance to saltwater corrosion eliminates the need for frequent replacements, reducing lifecycle costs for ship operators. In summary, factory-priced copper core PVC insulation flat cables are indispensable for maritime electrical systems. Their high-conductivity copper cores, marine-grade PVC insulation, and space-saving flat design address the unique challenges of shipping environments—vibration, corrosion, and limited space. Compliant with international maritime standards and available at competitive factory prices, these cables deliver reliability, safety, and cost-efficiency, making them a trusted choice for shipbuilders, offshore operators, and port authorities worldwide. Whether powering a cargo ship’s navigation system or an offshore platform’s machinery, they ensure uninterrupted performance in the harshest marine conditions.

"YJV" refers to the cable's insulation and sheath materials: "Y" denotes a cross-linked polyethylene (XLPE) insulation, which offers excellent thermal resistance, chemical stability, and electrical insulation properties, allowing the cable to operate at higher temperatures (typically up to 90°C) compared to traditional PVC-insulated cables. "J" indicates a copper conductor, known for its high electrical conductivity, ensuring minimal power loss during transmission. "V" signifies a polyvinyl chloride (PVC) sheath, which provides mechanical protection against abrasion, moisture, and environmental factors, ensuring durability and longevity in various installation conditions. The cables are available in multiple core configurations to accommodate different electrical systems. The 2-core and 3-core versions are commonly used in single-phase and three-phase power supply systems, respectively, while the 4-core and 5-core variants are specifically designed for three-phase four-wire systems. In three-phase four-wire applications, the additional neutral core (and sometimes a protective earth core in 5-core cables) facilitates balanced current distribution, protects against overvoltage, and ensures safe operation of electrical equipment. This versatility makes the ZR-YJV2 series adaptable to diverse scenarios, from powering industrial machinery and commercial buildings to residential electrical networks. Conductor cross-sectional areas range from 1.5mm² to 10mm², each suited to specific current-carrying capacities. Smaller sizes (1.5mm², 2.5mm²) are typically used for lighting circuits, small appliances, and low-power devices, while larger sizes (4mm², 6mm², 10mm²) are employed for higher-power equipment, distribution boards, and main supply lines. The copper core ensures efficient conductivity, reducing energy loss and maintaining stable voltage levels, which is essential for the reliable operation of sensitive electrical devices. Compliance with national standards is a cornerstone of the ZR-YJV2 series. These standards govern manufacturing processes, material quality, electrical performance (such as insulation resistance and dielectric strength), mechanical properties (including tensile strength and flexibility), and flame-retardant characteristics. Rigorous testing ensures that the cables meet or exceed these standards, guaranteeing consistent performance and safety across different batches and applications. Installation of ZR-YJV2 cables is flexible, as they can be laid in trenches, conduits, or directly buried, depending on the environment. The PVC sheath provides resistance to moisture and corrosion, making them suitable for both indoor and outdoor use, including damp or moderately harsh conditions. However, proper installation practices, such as avoiding excessive bending or exposure to extreme temperatures beyond the cable's rated limits, are recommended to maintain optimal performance. In summary, the ZR-YJV2 copper core cables represent a reliable and safe solution for three-phase four-wire power transmission. Their flame-retardant design, high-quality insulation and sheath materials, multiple core configurations, and adherence to national standards make them a preferred choice for engineers, electricians, and project managers seeking efficient, durable, and compliant electrical cabling.

This technical summary focuses on the Power Cable specified as 4c (4-core), rated for 0.6/1kV, featuring multiple cross-sectional area options (25mm², 240mm², 250mm², 300mm²), a copper core conductor, XLPE (cross-linked polyethylene) insulation, and steel wire armouring. Designed to meet the demanding requirements of medium-voltage power transmission and distribution systems, this cable combines durability, electrical performance, and adaptability to various installation environments, making it a reliable choice for both industrial and infrastructure applications. At the core of the cable lies its copper conductors, a material selected for its exceptional electrical conductivity, low resistivity, and excellent thermal stability. Copper ensures efficient power transmission with minimal energy loss, even under prolonged load conditions—critical for maintaining consistent performance in 0.6/1kV systems, which are commonly used in commercial buildings, manufacturing facilities, renewable energy projects (such as solar and wind farms), and urban power grids. The 4-core (4c) configuration further enhances functionality: it typically includes three phase conductors for power transmission and one neutral conductor for current balancing and fault protection, eliminating the need for separate neutral cables and simplifying installation. A key performance feature is the XLPE insulation surrounding each copper conductor. Cross-linked polyethylene offers superior electrical, mechanical, and thermal properties compared to traditional insulation materials like PVC. XLPE exhibits high dielectric strength, meaning it can withstand the 0.6/1kV voltage rating without breakdown, ensuring safe operation even in high-humidity or temperature-fluctuating environments. It also resists aging, chemical corrosion, and UV radiation, extending the cable’s service life—often exceeding 20 years in properly installed systems. Additionally, XLPE has low smoke and halogen emission characteristics, reducing health and fire hazards in the event of a cable fault, which is particularly important for occupied spaces or critical infrastructure. To enhance mechanical protection, the cable is equipped with steel wire armouring (SWA). This layer provides robust resistance to external impacts, compression, and rodent damage, making the cable suitable for both indoor and outdoor installations, including direct burial in soil, ducting, or exposed applications. The steel wire armour also offers excellent tensile strength, allowing the cable to be pulled through long distances during installation without structural damage. Unlike unarmoured cables, which require additional protective conduits, the SWA design reduces installation costs and complexity while ensuring long-term reliability in harsh conditions—such as industrial sites with heavy machinery, underground power distribution networks, or outdoor renewable energy installations exposed to weather and environmental stress. The cable is available in four key cross-sectional area sizes: 25mm², 240mm², 250mm², and 300mm², each tailored to specific current-carrying and power transmission needs. The smaller 25mm² option is ideal for low to medium current applications, such as secondary distribution in commercial buildings, connecting small electrical equipment, or branch circuits in industrial facilities. In contrast, the larger 240mm², 250mm², and 300mm² sizes are designed for high-current scenarios, including primary power distribution in industrial plants, connecting large transformers, or transmitting power from renewable energy generators (e.g., wind turbines or solar inverters) to the grid. This multi-size range ensures flexibility, allowing engineers and installers to select the optimal cable size based on load requirements, voltage drop considerations, and installation constraints—avoiding over-sizing (which increases costs) or under-sizing (which risks overheating and cable failure). Compliance with international standards is a cornerstone of this cable’s design. While specific standards may vary by region (e.g., IEC 60502 for power cables in many global markets, or ANSI/UL standards in North America), the cable is engineered to meet or exceed requirements for electrical performance, mechanical strength, fire safety, and environmental resistance. This compliance ensures interoperability with existing power systems, simplifies regulatory approval processes, and provides end-users with confidence in the cable’s reliability and safety. In summary, the 4c 0.6/1kV Multi Size Copper Core XLPE Insulated Steel Wire Armoured Power Cable stands out as a versatile, durable, and high-performance solution for medium-voltage power transmission and distribution. Its combination of copper conductors (for efficient conductivity), XLPE insulation (for electrical safety and longevity), steel wire armouring (for mechanical protection), and multiple size options (for adaptability) addresses the diverse needs of industrial, commercial, and infrastructure projects. Whether used in underground grids, industrial facilities, or renewable energy systems, this cable delivers consistent performance, reduces maintenance costs, and enhances safety—making it a critical component in modern power infrastructure.

The ZA-YJV32 0.6/1kV 3×50+25mm² Cu is a high-performance low-voltage (LV) power cable specifically engineered for direct underground installation (“pour pose souterraine”), tailored to meet the rigorous demands of residential, commercial, and light industrial power distribution networks. Designed to operate within the 0.6/1kV voltage range—0.6kV for phase-to-earth connections and 1kV for phase-to-phase connections—it serves as a critical link between LV substations and end-user electrical systems, delivering reliable power while withstanding the unique challenges of underground environments, such as soil pressure, moisture ingress, and external mechanical impacts. Its combination of high-conductivity copper conductors, durable cross-linked polyethylene (XLPE) insulation, flame-retardant properties, and robust steel tape armouring makes it a trusted choice for engineers and contractors seeking long-lasting, safe, and efficient underground power transmission solutions. A key starting point for understanding the cable’s capabilities is its model designation, which decodes its core attributes and design intent. “ZA” signifies flame-retardant Class A compliance (per GB/T 19666, a critical Chinese standard for cable safety), meaning the cable self-extinguishes within 60 seconds of removing an ignition source and emits minimal smoke and toxic gases. This is particularly vital for underground installations—where fire risks (e.g., from short circuits or adjacent utility failures) can lead to trapped smoke and difficult emergency response—ensuring safety for nearby infrastructure and personnel. “YJV” identifies the cable’s insulation and conductor setup: “Y” for XLPE insulation, “J” for a polyvinyl chloride (PVC) inner sheath, and “V” for copper conductors. This combination prioritizes electrical performance and environmental resilience, while “32” denotes the protective armouring and outer sheath: “3” for double steel tape armouring and “2” for a PVC outer sheath, together forming a barrier against mechanical damage and environmental contaminants. At the heart of the cable’s electrical efficiency is its copper conductor configuration: 3×50+25mm². This design includes three main phase conductors (each 50mm²) for balanced three-phase power transmission—the standard for LV grids worldwide—and one neutral conductor (25mm²) to handle unbalanced currents and provide a return path for single-phase loads (e.g., residential lighting or commercial appliances). The conductors are made from 99.95% pure stranded copper, a material chosen for its exceptional electrical conductivity (58 MS/m at 20°C) and low resistivity (1.72×10⁻⁸ Ω·m). Stranded construction enhances flexibility, allowing the cable to bend around underground obstacles (e.g., pipes, utility lines) during installation without conductor damage—unlike solid copper, which is prone to cracking under repeated bending. The 50mm² phase conductors deliver an ampacity of approximately 120A (at 25°C ambient temperature, direct burial), sufficient to power 50–80 average households (each with a peak load of 2–3kW) or a small commercial complex (e.g., a retail strip with 10–15 stores and associated HVAC systems). The cable’s XLPE insulation is a defining feature that sets it apart from traditional PVC-insulated cables for underground use. XLPE undergoes a cross-linking process (via electron beam or chemical agents) that transforms its linear molecular structure into a three-dimensional network, enhancing key properties critical for underground durability. It exhibits excellent thermal stability, operating reliably within a temperature range of -40°C to +90°C—making it suitable for diverse climates, from freezing northern regions to hot, humid southern areas. XLPE also resists moisture absorption (less than 0.1% by weight after 24 hours of immersion in water), a common threat to underground cables that can cause insulation breakdown and short circuits. Unlike PVC, which softens at high temperatures and degrades over time in soil, XLPE minimizes aging and chemical corrosion from soil contaminants (e.g., fertilizers, industrial runoff, or saltwater in coastal areas), extending the cable’s service life to 20+ years—double the typical lifespan of PVC-insulated underground cables. To address the mechanical challenges of underground installation, the ZA-YJV32 cable features double steel tape armouring (thickness ≥0.3mm) and a PVC outer sheath. The steel tape is applied in two overlapping layers, forming a rigid yet flexible barrier against soil compression (up to 100 kPa, equivalent to 10 meters of soil depth) that can deform unarmoured cables over time. It also protects against external impacts, such as accidental digging by construction equipment, falling rocks in compacted soil, or gnawing by rodents (e.g., rats or moles)—a leading cause of underground cable failures. The PVC outer sheath adds a secondary layer of protection, enhancing UV stability (critical if the cable is exposed during installation or maintenance) and resistance to oil, grease, and mild chemicals. This dual-protection system eliminates the need for additional protective conduits in most underground applications, reducing installation costs by 20–30% compared to unarmoured cables. Practical applications of the ZA-YJV32 0.6/1kV 3×50+25mm² Cu cable span residential, commercial, and light industrial sectors, each leveraging its unique strengths. In residential communities, the cable is directly buried at a depth of ≥0.7 meters (per IEC 60364 standards) to connect neighborhood LV substations to underground distribution boxes. From these boxes, smaller branch cables (e.g., 2.5mm² or 4mm² BVR cables) distribute power to individual homes, with the 120A ampacity easily supporting the combined load of 50–80 households. In commercial zones, it powers shopping malls, office parks, and retail centers, where its flame-retardant properties reduce fire risks in densely populated areas, and its steel armouring withstands soil compaction from parking lot construction or landscaping activities. For light industrial sites (e.g., small manufacturing plants, warehouses, or wastewater treatment facilities), the cable connects LV substations to control panels for machinery (pumps, compressors, conveyors), with its XLPE insulation resisting oil and chemical spills common in industrial yards. Compliance with international and regional standards further validates the cable’s reliability and safety. Beyond GB/T 19666 for flame retardancy, it adheres to IEC 60502-1 (a global standard for LV power cables) and local regulations for underground installation (e.g., China’s GB 50217 for power cable design). These standards govern critical parameters, including conductor purity, insulation thickness (minimum 1.2mm for XLPE), steel tape strength, and flame-retardant performance—ensuring the cable meets uniform safety and performance benchmarks across projects. For example, IEC 60502-1 requires the cable to pass a “water immersion test” (submerged in 23°C water for 24 hours with insulation resistance remaining ≥100 MΩ) and a “cold bend test” (bent around a mandrel at -15°C without insulation cracking), confirming its suitability for underground moisture and temperature fluctuations. In summary, the ZA-YJV32 0.6/1kV 3×50+25mm² Cu underground copper cable is a versatile, durable, and safe solution for LV power distribution. Its copper conductors deliver efficient energy transfer, XLPE insulation ensures long-term environmental resilience, steel tape armouring provides robust mechanical protection, and ZA-class flame retardancy enhances safety—all tailored to the unique demands of underground installation. Whether powering residential neighborhoods, commercial complexes, or light industrial facilities, it consistently delivers reliable performance, minimizes maintenance costs, and complies with global standards—making it an indispensable component of modern underground electrical infrastructure.
