Products Description
Tinned Copper 6mm² Solar PV DC Cable is purpose-built for solar photovoltaic systems, delivering consistent power transmission, exceptional durability, and strict compliance with international standards. Designed for 1000V DC (compatible with 1500V DC systems) and rated IP68 for dust and water protection, this cable ensures stable operation in harsh outdoor environments-from deserts and rooftops to coastal and mountain installations. Backed by TUV, CE, and ISO certifications, it meets EN 50618 (H1Z2Z2-K), IEC 62930, and UL 4703, making it a trusted choice for residential, commercial, and utility-scale solar projects.
Every component is manufactured to exacting tolerances, balancing conductivity, flexibility, and environmental resistance.
1. Conductor: Class 5 Tinned Copper (6mm²)
Material: 99.9% pure electrolytic annealed copper, tinned for corrosion resistance and reduced oxidation at connections.
Structure: 81 strands × 0.30mm (Class 5 flexible, IEC 60228), ensuring high flexibility for easy installation in tight spaces while maintaining optimal conductivity.
DC Resistance: 3.39 Ω/km at 20°C, minimizing power loss and ensuring efficient energy transfer.
Advantage: Tinned copper outperforms bare copper in UV-exposed and humid environments, extending service life to 25+ years.
2. Insulation & Sheath: Double-Layer XLPE (Cross-Linked Polyethylene)
Material: Electron-beam cross-linked XLPE (XLPO), halogen-free, low-smoke, flame-retardant (UL94 V-0).
Insulation Thickness: 0.8–1.0mm; Sheath Thickness: 0.8–1.0mm, providing double protection against mechanical damage, chemicals, and extreme temperatures.
Temperature Range: -40°C to +90°C (continuous); 120°C (max conductor, 20,000hrs); 250°C (short-circuit, ≤5s).
Environmental Resistance: UV-stabilized, ozone-resistant, water/dustproof (IP68), and oil-resistant-withstand prolonged outdoor exposure without aging or degradation.
3. Physical Dimensions
Nominal Cross-Section: 6mm²
Outer Diameter: 6.5–7.1mm (compact for easy routing).
Standard Colors: Red (positive), Black (negative) (custom colors available)
Datasheet

Manufacturing Process – Rigorous Quality Control
Our cables are produced in an ISO 9001-certified smart factory with automated production lines and 100% digital inspection, ensuring consistent quality across every batch.
Conductor Stranding: Precision stranding of tinned copper wires (tolerance ±0.002mm) for uniform conductivity and flexibility.
XLPE Extrusion: Double-layer extrusion of XLPE insulation and sheath under controlled temperature/pressure, ensuring seamless bonding and consistent thickness.
Electron-Beam Cross-Linking: High-energy electron beam treatment to cross-link XLPE, enhancing thermal stability, chemical resistance, and mechanical strength.
100% Testing: Every cable undergoes spark test (6kV AC), voltage withstand test, insulation resistance test (≥1MΩ/km), and dimensional inspection.
Certification & Marking: Batch certification with TUV/CE/ISO; sequential meter marking for traceability.
Applications
PV System Wiring: Connect solar panels, combiner boxes, inverters, and batteries (DC side).
Installation Scenarios: Rooftop solar, ground-mounted power stations, floating PV plants, and industrial solar systems.
Environments: Desert (high temp/UV), coastal (salt spray/humidity), mountain (cold/ice), and agricultural (chemical exposure).
