Material purity: 99.7% high-purity aluminum (per IEC 60228), ensuring consistent conductivity and corrosion resistance. Impurities are limited to ≤0.3% (e.g., iron, silicon), preventing increased resistance or brittleness.
Cross-sectional area range: 10mm² to 50mm², covering diverse load demands. Common specifications include:
10mm²: Rated current-carrying capacity 60A (30℃ ambient), suitable for street lighting, small residential branches.
25mm²: 110A capacity, ideal for general residential/commercial distribution (supports 20-30 households).
50mm²: 180A capacity, for industrial auxiliary lines or large residential complexes.
Stranding structure: Class 2 stranded (IEC 60228) – 7 strands for 10-25mm² (1+6 configuration, strand diameter 1.38-2.12mm) and 19 strands for 50mm² (1+6+12 configuration, strand diameter 1.83mm). This design enhances Flexibility, with a minimum bending radius of 12× conductor diameter (e.g., 25.4mm for 25mm²), facilitating installation around poles or terrain obstacles.
DC resistance: At 20℃, 2.06Ω/km (10mm²), 0.81Ω/km (25mm²), 0.405Ω/km (50mm²) – ensuring low power loss. For a 10km 25mm² cable, resistance causes a voltage drop of 8.91V at 110A, well within the 5% maximum allowed by IEC 60502-1.

XLPE additives: Silane cross-linking agents (for molecular bonding), UV stabilizers (carbon black, 2-3% concentration), and antioxidants (hindered phenols) to enhance weather resistance.
PVC additives: Plasticizers (dioctyl phthalate, 30-40% concentration) for flexibility, UV absorbers (benzophenones), and heat stabilizers (calcium-zinc compounds) to mitigate thermal degradation.
Core configuration: 2-core (1 phase + 1 neutral) or 4-core (3 phases + 1 neutral). Phase conductors are color-coded (red/yellow/blue for 3-phase; red for single-phase) and neutral conductors are black for easy identification.
Lay length: 500mm (20× bundle diameter) – ensures tight binding without conductor separation during wind or vibration. The 2-core bundle (25mm²) has an outer diameter of 10.5mm (XLPE) / 9.8mm (PVC); the 4-core bundle is 15.2mm (XLPE) / 14.5mm (PVC).
Outer sheath (optional): A 0.8mm thick XLPE/PVC Sheath is available for harsh environments (e.g., coastal salt spray). The sheath adds UV and Chemical Resistance, with the XLPE sheath offering better aging performance (retains 80% tensile strength after 10 years vs. 60% for PVC).
Weight efficiency: Density 2.7g/cm³ vs. copper’s 8.9g/cm³. A 1km 25mm² aluminum conductor weighs 67.5kg, vs. 222.5kg for copper – reducing pole load by 70%. This allows the use of reinforced concrete poles (300kg) instead of steel poles (800kg), cutting pole costs by 30-40%.
Cost savings: Aluminum’s market price is ~1/3 that of copper. For a 100km project, Aluminum Conductors save \(200,000-\)300,000, a key factor for budget-constrained rural grid upgrades.
Corrosion resistance: Aluminum forms a 0.01mm-thick Al₂O₃ oxide film within seconds of air exposure. This film is impermeable to water and oxygen, preventing rust. For coastal areas, an 8-12μm zinc coating is added – passing ISO 9227 salt spray testing (no corrosion after 1000 hours).
XLPE (Cross-Linked Polyethylene):
Performance drivers: The silane cross-linking process creates a three-dimensional molecular network, enhancing temperature resistance and mechanical strength. Unlike linear polyethylene, it does not soften at high temperatures, making it suitable for urban areas with high summer temperatures (45℃+) or industrial zones with load fluctuations.
Environmental benefits: Halogen-free and low-smoke properties reduce fire risks in populated areas. For example, in a residential fire, XLPE releases no toxic HCl gas, while PVC can emit gas that irritates the respiratory system.
Longevity: Accelerated aging tests (IEC 60811-404) show XLPE retains 90% of its tensile strength after 20,000 hours (25 years), doubling PVC’s service life.
PVC (Polyvinyl Chloride):
Cost advantage: PVC resin costs ~50% less than XLPE compound. For projects with short service life expectations (e.g., temporary construction sites), PVC offers immediate cost savings without compromising basic performance.
Processing ease: PVC has a lower melting point (160-180℃ vs. XLPE’s 180-200℃) and simpler extrusion process, reducing production time by 20% and minimizing manufacturing defects.
Flexibility at low temperatures: PVC remains flexible at -10℃ (vs. XLPE’s -20℃ brittleness temperature), making it suitable for mild-cold regions (e.g., southern China, Southeast Asia) where temperatures rarely drop below -5℃.
Urban residential/commercial distribution: In cities like Shanghai or Mumbai, where summer temperatures reach 40℃+ and loads fluctuate (e.g., EV charging, air conditioning), XLPE’s 90℃ working temperature and low dielectric loss (tanδ 0.0005-0.001) ensure stable operation. The bundled structure reduces faults from tree branches (60% fewer outages vs. traditional conductors), critical for minimizing disruptions in dense areas.
Industrial parks: XLPE’s chemical resistance (per IEC 60811-2-1) withstands industrial dust, oils, and mild acids in zones like manufacturing plants or logistics hubs. For example, in a textile factory, the cable resists fiber accumulation and oil mist, maintaining insulation performance for 20+ years.
Coastal regions: The optional XLPE outer sheath, combined with zinc-coated aluminum conductors, resists salt spray corrosion. In coastal cities like Shenzhen or Dubai, this version operates reliably in high-humidity, salt-rich air without conductor degradation.
Rural power grid transformation: In rural areas of India or Africa, where load density is low (average 1-2kW per household) and temperatures are mild (25-35℃), PVC’s 70℃ working temperature is sufficient. Its lower cost (20-30% cheaper than XLPE) allows utilities to expand coverage to remote villages with limited budgets.
Temporary infrastructure: For construction sites, temporary markets, or disaster relief camps, PVC’s short-term durability (5-10 years) and easy recyclability make it practical. After the project ends, the cable can be recycled (PVC insulation and aluminum conductor separated) to reduce waste.
Agricultural irrigation: In farmland areas, PVC’s resistance to water and mild fertilizers ensures reliable power supply for irrigation pumps. The lightweight design allows installation along field ridges without heavy machinery.
Rod drawing: 99.7% pure aluminum rods (Φ9.5mm) are heated to 650℃ in a continuous casting furnace, then drawn into strands (Φ1.38-2.12mm) using a wire drawing machine. A water-based lubricant (polyethylene glycol) prevents surface scratches, ensuring strand smoothness.
Stranding: Strands are twisted into conductors using a 7/19-strand stranding machine, with tension controlled at 50N per strand to maintain the 1+6/1+6+12 structure. The stranding speed is 15m/min for 10-25mm² and 12m/min for 50mm².
Annealing: Conductors are annealed in a nitrogen-protected furnace (300℃, 2 hours) to soften aluminum (yield strength reduced from 120MPa to 80MPa), improving bending performance and reducing installation stress.
XLPE Insulation Extrusion:
Preheating: Conductors are heated to 80℃ to remove moisture, ensuring adhesion to insulation.
Compound preparation: XLPE resin is mixed with 2% silane cross-linking agent, 2.5% carbon black (UV stabilizer), and 0.5% antioxidant in a twin-screw mixer (120℃, 10 minutes).
Extrusion: The compound is fed into an extruder (barrel temperature 180-200℃), then forced through a cross-head die to form the insulation layer (1.2-1.5mm thick). A laser diameter gauge monitors thickness in real time, with ±0.1mm tolerance.
Cross-linking: The Insulated Conductor enters a 80℃ water bath for 24 hours. Silane reacts with water to form chemical bonds between polyethylene molecules, transforming the structure into a three-dimensional network.
Testing: Insulation resistance (≥1000MΩ·km) and dielectric strength (10kV AC) are tested; defective sections are rejected.
PVC Insulation Extrusion:
Compound preparation: PVC resin is mixed with 35% plasticizer (DOP), 3% calcium-zinc stabilizer, 2% UV absorber, and 1% lubricant (stearic acid) in a high-speed mixer (100℃, 8 minutes).
Extrusion: The compound is extruded at 160-180℃ (lower than XLPE) through a cross-head die, forming a 1.0-1.2mm thick layer. Extrusion speed is 20m/min (faster than XLPE) due to PVC’s lower viscosity.
Cooling: The insulated conductor is cooled in a 25℃ water bath for 5 minutes (no cross-linking needed, as PVC is thermoplastic).
Testing: Insulation resistance (≥500MΩ·km) and dielectric strength (8kV AC) are verified; samples are checked for flexibility (bending test at -10℃ with no cracks).
Color coding: Insulated conductors are colored during extrusion (red/yellow/blue/black) for phase identification.
Bundling: Conductors are fed into a bundling machine, twisted into 2/4-core bundles with a 500mm lay length. Tension is 100N per conductor to ensure tight binding.
Sheath extrusion (optional): For harsh environments, a 0.8mm thick XLPE/PVC sheath is extruded over the bundle. XLPE sheath uses the same cross-linking process as insulation; PVC sheath is extruded at 160℃ and cooled immediately.
Final testing: All cables undergo:
Mechanical tests: Tensile strength (sheath ≥12MPa for XLPE, ≥10MPa for PVC), elongation at break (≥200% for XLPE, ≥150% for PVC).
Environmental tests: UV resistance (ISO 4892-2, 168 hours) and water resistance (IPX7 submersion).
Electrical tests: Insulation resistance and dielectric strength of the complete cable.
Drum specifications: Outer diameter 1200mm, inner diameter 500mm, height 800mm, made of 18mm thick plywood. Reinforced with 4mm steel hoops to prevent deformation during transit.
Cable protection:
XLPE version: Wound with 200N tension, wrapped in 0.2mm waterproof polyethylene film (UV-resistant) to protect against sun damage during storage.
PVC version: Wound with 180N tension (lower than XLPE to avoid sheath deformation, as PVC is slightly less rigid), wrapped in 0.18mm waterproof polyethylene film with an additional layer of kraft paper to prevent UV degradation (PVC is more sensitive to sunlight than XLPE).
Labeling: Each drum features a 15cm×20cm weather-resistant label with:
Product details: XLPE/PVC Insulated ABC Cable, 0.6/1kV, 25mm² (or other specs), 2-core/4-core.
Insulation type (clearly marked "XLPE" or "PVC" in bold font to avoid confusion).
Batch number, production date, and test certification marks (IEC 60502-1, ISO 9001).
QR code linking to digital test reports, installation guides, and safety data sheets (SDS) – critical for PVC versions, as SDS includes handling precautions for halogen-containing materials.
Safety warnings: "Store in shaded area" (emphasized for PVC), "Avoid mechanical impact," "Do not expose to temperatures >70℃ (PVC) / 90℃ (XLPE)".
Tube specifications: Outer diameter 200mm, inner diameter 80mm, length 1.2m, made of 5mm thick corrugated cardboard with a waterproof coating (polyethylene for XLPE, kraft paper + polyethylene for PVC).
Cable protection:
XLPE version: 100m/200m/500m lengths wound onto tubes, wrapped in two layers of 0.15mm polyethylene film (inner for dust, outer for UV resistance).
PVC version: Same length options, wrapped in two layers of 0.15mm polyethylene film plus a layer of aluminum foil to block UV rays, reducing sheath aging during on-site storage.
Labeling and portability: Each small roll has a 10cm×15cm label with condensed product details (specs, insulation type, batch number) and a built-in handle cut into the cardboard tube. The total weight of a 100m Roll is ~10kg (XLPE) / 9.5kg (PVC), allowing a single worker to carry it to remote installation points (e.g., rural utility poles or rooftop aerial lines).
Road Transport: Ideal for orders within 500km, especially small-to-medium batches (1-5 drums or 10-20 small rolls). We use specialized trucks with air suspension systems to minimize vibration – critical for PVC versions, as excessive vibration can cause sheath micro-cracks. Key precautions include:
XLPE version: Drums secured to 120cm×100cm wooden pallets with steel straps (500N tension), foam padding (5cm thick) between drums.
PVC version: Drums/rolls packed with additional bubble wrap (3cm thick) around the outer layer to protect against impact, as PVC’s sheath is slightly more brittle than XLPE’s.
GPS tracking is provided, and customers receive real-time updates via our portal. Delivery time: 1-3 days.
Rail Transport: Cost-effective for large bulk orders (10+ drums) traveling over 500km. We reserve covered freight cars with temperature monitoring (to ensure ambient temperatures stay below 40℃, as PVC can soften at higher temperatures). Drums are arranged in a grid pattern with dunnage bags (inflated to 80kPa) filling gaps to prevent shifting. Rail transport is less affected by weather, making it reliable for time-sensitive rural grid projects. Delivery time: 3-7 days.
Water Transport: For coastal regions or areas with inland waterway access (e.g., China’s Yangtze River, India’s Ganges), water transport is used for very large orders (50+ drums). Cables are loaded into 20-foot containers with:
XLPE version: Desiccant bags (1kg each) to absorb humidity.
PVC version: Desiccant bags plus a dehumidifier (set to 50% relative humidity) to prevent moisture absorption, as PVC is more prone to hydrolysis than XLPE.
Sea Freight: The primary choice for bulk orders (1000m+). We work with carriers like Maersk, COSCO, and CMA CGM to ship cables in 20-foot or 40-foot containers. Key considerations for each version:
XLPE version: Wooden drums include IPPC certification (ISPM 15) to avoid pest-related customs delays. Containers are ventilated to prevent heat buildup.
PVC version: Drums are lined with aluminum foil to block UV rays (critical for long sea voyages in direct sunlight). Additional documentation includes a "Halogen-Containing Material Declaration" for customs compliance in regions with strict environmental regulations (e.g., EU, Japan).
Air Freight: For urgent orders (e.g., emergency repairs after storms), air freight via DHL, FedEx, or UPS is available. Small rolls are packed into lightweight cardboard boxes (max 500m per box) with:
XLPE version: Foam padding to prevent impact damage.

Installation guidance (e.g., maximum tension during erection: 300N for 25mm², bending radius ≥12× diameter).
Troubleshooting (e.g., low insulation resistance – check for moisture ingress, as XLPE is hygroscopic if damaged).
Maintenance advice (annual insulation resistance testing with a 5kV megohmmeter, visual inspection for UV cracks).
PVC version support: Engineers focus on:
Installation limits (e.g., maximum tension: 250N for 25mm², as PVC sheath is less durable; avoid installation in direct sunlight).
Troubleshooting (e.g., sheath hardening – sign of UV aging, recommend replacement or adding a UV protective sleeve).
Maintenance advice (semi-annual visual inspections for sheath discoloration, avoid exposing to temperatures >70℃).
XLPE projects: Engineers supervise cross-linking verification (if on-site splicing is needed) and train teams on handling the more rigid insulation.
PVC projects: Engineers train teams on proper tension control and UV protection measures (e.g., installing the cable in shaded areas or using UV-resistant tape).
XLPE version: 10-year warranty against manufacturing defects (insulation breakdown, conductor corrosion, sheath cracking). Covers damage from mild salt spray and UV exposure (up to 10 years of outdoor use).
PVC version: 5-year warranty against manufacturing defects. Does not cover UV aging (expected after 5-10 years) or damage from temperatures >70℃, as PVC’s service life is shorter.
Improper installation (e.g., exceeding bending radius, tension overload).

XLPE version: Free replacement cables with expedited cross-linking (domestic delivery within 3 days) and coverage of labor costs for removal/installation.
PVC version: Free replacement cables (domestic delivery within 2 days) and a 10% discount on future orders (to offset frequent maintenance needs).
Objection Registration: Customers report issues via the portal/email, with insulation type clearly noted. A specialist logs details and assigns a tracking ID within 2 hours.
Technical Assessment:
XLPE issues: Engineers review batch cross-linking records and may test samples for dielectric strength.
PVC issues: Engineers review UV stabilizer additive records and test samples for flexibility.
Solution Proposal:
XLPE: Minor thin spots – provide free protective sleeves; insulation resistance issues arrange on-site testing to identify moisture ingress points and provide sealing kits.
PVC: Minor discoloration – offer free UV-resistant spray to slow aging; sheath brittleness – provide discounted replacement sections (20% off) to prevent further damage.
Implementation and Follow-Up:
For XLPE solutions: Protective sleeves or sealing kits are shipped within 48 hours, with a technical engineer following up 2 weeks later to confirm installation and test insulation resistance.
For PVC solutions: UV spray or replacement sections are delivered within 36 hours, and a specialist checks in 1 month later to monitor sheath condition and adjust maintenance advice if needed.
Customized Maintenance Manuals:
XLPE Version Manual: Includes annual inspection checklists (e.g., visual inspection for UV cracks, insulation resistance testing with a 5kV megohmmeter), guidelines for on-site splicing (using heat-shrinkable XLPE sleeves), and troubleshooting for moisture ingress (e.g., using a moisture meter to locate leaks). It also details long-term care (every 5 years: comprehensive dielectric strength testing) to extend the 10-year warranty to 15 years for well-maintained cables.
PVC Version Manual: Focuses on semi-annual checks (e.g., sheath flexibility tests, discoloration assessment) and seasonal precautions (e.g., pre-summer UV spray application, winter tension adjustments to avoid brittleness). It includes a "service life calculator" based on environmental factors (e.g., 5 years in direct sunlight, 8 years in shaded areas) to help users plan replacements proactively.
Annual Follow-Up Programs:
For XLPE users with 50km+ installations: We conduct annual remote audits via our customer portal, reviewing maintenance logs and insulation resistance test data. If resistance values drop by more than 10% year-over-year, we dispatch an engineer to identify issues (e.g., damaged sheaths, water intrusion) and provide corrective actions.
For PVC users in harsh environments (e.g., tropical regions, industrial zones): We offer bi-annual on-site visits, where engineers test sheath flexibility, measure UV damage, and update maintenance plans (e.g., increasing UV spray frequency from annual to semi-annual).
End-of-Life Recycling and Disposal:
XLPE Version: XLPE insulation and aluminum conductors are fully recyclable. We partner with certified recycling facilities to separate the two materials – aluminum conductors are melted and reused in new cable production (recycling efficiency >95%), while XLPE insulation is processed into plastic pellets for non-electrical applications (e.g., pipe fittings). We offer free recycling pickup for large quantities (1000m+), with a certificate of recycling provided to meet environmental compliance requirements.
PVC Version: Due to halogen content, PVC requires specialized disposal. We coordinate with facilities licensed to handle halogen-containing plastics – PVC insulation is incinerated in controlled environments with scrubbers to remove HCl gas (emission levels <0.1mg/m³), and aluminum conductors are recycled separately. For customers in the EU (compliant with REACH regulations), we provide a "Waste Electrical and Electronic Equipment (WEEE)" certificate to document proper disposal, avoiding fines for improper waste management.
Insulation-Specific Optimization: XLPE caters to high-performance needs (urban, industrial, coastal regions) with 90℃ working temperature, low energy loss, and 10-year warranty; PVC targets cost-sensitive, mild environments (rural, temporary projects) with 70℃ working temperature, 30% lower cost, and simplified processing. This duality ensures no compromise between performance and budget.
Aluminum Conductor Advantage: Lightweight (70% lighter than copper) and corrosion-resistant, aluminum reduces pole costs by 30-40% and installation labor by 30%, making it ideal for aerial use. The stranded design enhances flexibility, adapting to complex terrain in rural or urban areas.
Bundled Structure Efficiency: The 2/4-core bundle reduces line space by 62.5% vs. traditional conductors, supports "capacity expansion without pole addition" in cities, and cuts faults by 60% – critical for reliable power supply in all scenarios.
End-to-End Customer Support: From insulation-specific packaging (UV protection for PVC, moisture barriers for XLPE) and transportation (temperature control for PVC) to tailored after-sales service (10-year vs. 5-year warranty, recycling solutions), every step is designed to address the unique needs of each version.
