The XLPE Insulated 3+2 Cores Copper Cable (3×240+2×120mm²) is a low-voltage power cable designed for applications requiring both power distribution and protective grounding. With three phase conductors and two additional conductors (commonly used as protective earth or auxiliary lines), this cable ensures safe, efficient power delivery in industrial and infrastructure settings.
It is manufactured in accordance with IEC 60502-1 and IEC 60228, suitable for fixed installations in indoor and outdoor environments, including cable ducts, trays, direct burial, and industrial power networks.
Applications
Power supply in low-voltage distribution networks (600/1000V)
Industrial facilities requiring high-capacity power transmission with grounding
Utility and infrastructure projects needing large cross-section copper cores
Outdoor installations where robust mechanical and thermal performance is required
Standards
IEC 60228 – Conductors of insulated cables
IEC 60502-1 – Power cables with extruded insulation and their accessories for rated voltages up to 1 kV and 3 kV
