This 3x10+1x6mm² 3+1 Cores XLPE Insulated Copper Cable is a low voltage power cable for distribution systems that require a separate earth wire. The cable features three 10mm² copper phase conductors and a single 6mm² copper earth conductor. It is insulated with XLPE and protected by a durable PVC outer sheath. It is commonly referred to as an IEC 60502 3 core and earth cable.

Applications

The 3+1 core configuration is specifically designed for installations where a separate earth conductor is required. Applications include:

  • Power Distribution: For mains, sub-mains, and sub-circuit wiring in urban networks and industrial plants.
  • 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 it is not subjected to mechanical damage.
  • Specialized Wiring: The additional earth conductor is essential for safety and is often used in applications like two-way lighting 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+1 Cores Cable Construction

The cable's construction consists of the following layers:

  1. Conductor: Plain annealed copper, Class 2 (stranded).
  2. Insulation: Cross-linked polyethylene (XLPE) for excellent electrical properties and high-temperature performance.
  3. Filler: A 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.
