This product is a Na2xy type triple-core power cable (Tripolar Cable De Energia) with a specification of 3-1×70mm², a rated voltage of 0.6/1kV, and the sheath colors include red, black and white.​ The cable has a three-core structure with a single-core cross-sectional area of 70mm², which can meet the power transmission needs of corresponding loads. The rated voltage of 0.6/1kV is suitable for low-voltage power distribution scenarios and can be used in fixed laying scenarios such as building power distribution and power supply for small industrial equipment.​ The sheath is designed in red, black and white colors, which not only facilitates phase differentiation during installation and reduces the risk of wiring errors, but also can intuitively identify the cable's purpose or laying path through colors. Its overall structure is suitable for low-voltage electricity environments and can operate stably in conventional dry and ventilated environments, providing reliable guarantee for power transmission.

This product is a Na2xy type triple-core power cable (Cable De Energia Tripolar) with the specification of 3-1×240mm² and a rated voltage of 0.6/1kV, suitable for medium and low-voltage power distribution scenarios.​ "3-1×240mm²" indicates that the cable adopts a three-core independent structure with a single-core conductor cross-sectional area of 240mm², which can carry a large current (long-term allowable current-carrying capacity is about 400A at 25℃ ambient temperature). It can meet the high-power power transmission needs of large industrial equipment, building main distribution and other scenarios. The rated voltage of 0.6/1kV is compatible with low-voltage power grid standards and meets the voltage requirements of conventional power distribution systems.​ The cable usually uses copper as the conductor material, with excellent conductivity; the insulation layer and sheath are mostly made of temperature-resistant and corrosion-resistant polyvinyl chloride (PVC) or other suitable materials, which can operate stably in various environments such as dry and humid conditions. The three-core structure design facilitates three-phase power transmission and is suitable for industrial and civil three-phase power supply systems.​ It has a wide range of application scenarios, such as main power supply for factory production lines, main distribution lines of commercial complexes, and power distribution systems of high-rise buildings. It can meet the power supply needs of high-power equipment through the advantage of large cross-sectional area.

The N2XRY armored cable is a high-performance power cable designed for complex energy transmission scenarios, whose structural design and material selection fully meet the stringent requirements for safety, durability, and efficiency in industrial, municipal, and energy sectors. The designation "N2XRY" directly reflects its core composition and performance characteristics, where "N" denotes fire resistance, "2" indicates suitability for higher temperature environments, "X" refers to cross-linked polyethylene (XLPE) insulation, "R" corresponds to polyvinyl chloride (PVC) sheathing, and "Y" implies the flexibility and adaptability of its overall structure. Structurally, the N2XRY cable features a multi-layer composite design. The core conductor is made of high-purity copper (CU), which exhibits excellent electrical conductivity, effectively reducing energy loss during transmission and ensuring efficient power delivery. The conductor is wrapped in a cross-linked polyethylene (XLPE) insulation layer, a material known for its high voltage resistance, aging resistance, and temperature tolerance. It can operate stably in environments ranging from -40°C to 90°C, significantly enhancing the cable's insulation reliability and preventing safety hazards such as short circuits and leakage. To further enhance the cable's mechanical protection, a steel wire armor (SWA) structure is applied over the XLPE insulation. The steel wire armor, either spirally wound or longitudinally wrapped, provides robust resistance to impact, extrusion, and stretching. This allows the cable to withstand external pressures from underground laying, burial projects, or vibrations from industrial equipment, while also effectively resisting gnawing by rodents, thereby extending the cable's service life. Externally, the armor layer is covered with a polyvinyl chloride (PVC) outer sheath. PVC not only offers excellent corrosion resistance, protecting against chemicals, moisture, and ultraviolet radiation in the soil, but also provides a degree of flame retardancy, complying with fire safety standards. It is particularly suitable for industrial environments with humidity, dust, or flammable risks. The N2XRY cable finds extensive applications, including urban power grid transformation, industrial park distribution systems, power transmission in high-rise buildings, and grid-connection lines of new energy power stations (e.g., photovoltaic and wind power). In these scenarios, the cable must cope with complex environmental conditions and high-load power transmission demands. With its multi-layer protective structure and high-performance material combination, N2XRY stably ensures continuous power supply and reduces maintenance costs. Moreover, the cable is designed for easy installation. The flexibility of the steel armor allows for easy bending and laying, reducing construction difficulties. Additionally, its standardized specifications (with cross-sectional areas ranging from 10mm² to 400mm²) can meet transmission needs of different power levels, adapting to various wiring equipment. In summary, the N2XRY armored cable achieves a comprehensive balance of conductivity, insulation safety, mechanical protection, and environmental adaptability through the scientific combination of copper conductors, XLPE insulation, steel armor, and PVC sheathing. It is an ideal choice in modern energy transmission, offering both reliability and cost-effectiveness
