This 3+1 Cores XLPE Insulated Copper Cable is a low voltage cable designed for power transmission and distribution systems where a dedicated earth wire is required. Commonly referred to as an IEC 60502 3 core and earth cable, it features three insulated copper phase conductors plus a single, dedicated earth conductor. The cable is insulated with cross-linked polyethylene (XLPE) and protected by a durable polyvinyl chloride (PVC) outer sheath.
Applications
The 3+1 core cable configuration is specifically designed for installations requiring a separate earth wire. Its applications include:
- Power Distribution: Used in urban networks, industrial plants, and general energy distribution systems.
- Indoor and Outdoor Installations: Suitable for use in damp and wet environments.
- Fixed Wiring: Can be installed unenclosed, in conduits, or buried directly in underground ducts where not subjected to mechanical damage.
- Specialized Wiring: Frequently used for two-way lighting circuits, where the additional conductor is required between two switches controlling a single light fitting.
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
The cable is constructed with the following components:
- Conductor: Plain annealed copper, available in Class 1 (solid) or Class 2 (stranded) configurations.
- Insulation: Cross-linked polyethylene (XLPE) for high-temperature performance and excellent electrical properties.
- Filler: Non-hygroscopic material to maintain a circular shape and prevent moisture ingress.
- Binder Tape: A non-hygroscopic tape to secure the cores in place.
- Outer Sheath: A durable polyvinyl chloride (PVC) outer layer for mechanical protection.
