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)
