The XLPE insulated 3-core 400mm² copper cable is a high-capacity power cable designed for reliable transmission and distribution of electricity in both industrial and commercial applications. Constructed with cross-linked polyethylene (XLPE) insulation and copper conductors, this cable offers excellent electrical performance, mechanical strength, and thermal resistance. It complies with international standards and is widely used in medium- to low-voltage installations.
Application
This 3-core XLPE insulated copper cable, rated 0.6/1kV (IEC 60502 CU/XLPE/PVC), is suitable for indoor and outdoor installations, including damp and wet environments. Common applications include:
Power distribution in urban networks and industrial facilities
Mains and submains for buildings and substations
Installation in conduits, ducts, direct burial, or cable trays
Areas where space is limited and flexibility is essential
Suitable for installations not subject to severe mechanical stress
Maximum operating temperature:
90°C continuous (XLPE insulation)
250°C short circuit (5s max)
Standards
IEC 60228 – Conductors of insulated cables
IEC 60502-1 – Power cables with extruded insulation for rated voltages of 1kV (Um = 1.2kV) and 3kV (Um = 3.6kV)
