4 Core 5 Core 70mm² Copper Power Cable XLPE/PVC Sheathed Under Ground Cable

1. Specifications & Parameters

• Conductor Material: High-purity electrolytic copper, excellent conductivity, low resistance for efficient power transmission.

• Insulation Material: XLPE (cross-linked polyethylene) insulation for high-temperature and aging resistance, PVC (polyvinyl chloride) outer sheath for waterproof and anti-corrosion protection.

• Structure: 4-core (3 phases + earth) or 5-core (3 phases + neutral + earth), 70mm² cross-section, suitable for high-current loads.

• Voltage Rating: Typically 0.6/1kV, ideal for low-voltage distribution systems.

• Application Environment: Suitable for direct burial, cable trenches, duct laying, and harsh conditions like damp or corrosive soil.

2. Features & Applications

• High Durability: XLPE insulation withstands up to 90°C (250°C under short-circuit), ensuring long service life.

• Safety & Reliability: Copper Core resists oxidation; insulation is flame-retardant and chemical-resistant, complying with international standards (IEC, GB, etc.).

• Applications: Industrial power supply, building distribution, municipal projects, tunnel lighting, mining equipment, and other scenarios requiring stable power.

3. Production Process

• Conductor Stranding: Fine Copper Wires twisted for Flexibility and bending resistance.

• Triple Co-Extrusion: Conductor shielding, XLPE insulation, and outer sheath formed in one step for uniform insulation.

• Strict Testing: High-voltage, insulation resistance, and partial discharge tests ensure quality per meter.

4. Packaging & Shipping

• Standard Packaging: Wooden or steel-wooden reels, wrapped with waterproof film for moisture and damage protection.

• Shipping Methods: Land or sea freight, full reels or custom-cut lengths available.

• Delivery Time: Standard sizes in stock; special orders delivered in 7-15 days.

5. Samples & After-Sales

• Samples: Small samples available for testing before bulk orders.

• Service: Warranty (1-3 years) covers non-manual damage; technical support and installation guidance provided.
