This 3x120+2x70mm² 3+2 Cores XLPE Insulated Copper Cable is a low-voltage power cable designed for applications that require three phase conductors and two neutral/earth conductors. The cable features three 120mm² copper phase conductors and two 70mm² copper neutral/earth conductors. It is insulated with XLPE and protected by a durable PVC outer sheath. This type is commonly referred to as an IEC 60502 3 cores + 2 cables.

Applications

The 3+2 core configuration is specifically designed for installations where two separate earth conductors are required for safety and compliance. Its applications include:

  • Power Distribution: For mains, sub-mains, and sub-circuit wiring in urban networks, industrial plants, and buildings.
  • Indoor and Outdoor Installations: Suitable for use in damp and wet locations.
  • Fixed Installations: Can be installed unenclosed, in conduits, or buried directly in underground ducts where not subjected to mechanical damage.
  • Specialized Wiring: The additional earth conductors are essential for safety in many circuits.

Standards Compliance

This cable is manufactured and tested to comply with the following international standards:

  • Conductors: IEC 60228
  • Design Specification: IEC 60502-1 - Power cables with extruded insulation and their accessories for rated voltages from 1 kV ( = 1.2 kV) up to 35 kV ( = 40.5 kV) - Part 1: Cables for rated voltages of 1 kV ( = 1.2 kV) and 3 kV ( = 3.6 kV).

Construction Details

XLPE 3+2 Cores Cable Construction

The cable's construction consists of the following components:

  1. Conductor: Plain annealed copper, Class 2 (stranded).
  2. Insulation: Cross-linked polyethylene (XLPE) for excellent electrical properties and high-temperature performance.
  3. Filler: Non-hygroscopic material to maintain a circular shape and prevent moisture ingress.
  4. Binder Tape: A non-hygroscopic tape to secure the cores in place.
  5. Outer Sheath: A durable polyvinyl chloride (PVC) outer layer for mechanical protection.
