Underground Medium Voltage Cable

This Underground power circuits featuring three-phase AC voltage insulated cable with a rated voltage between 6.6kV and 36kV. These lines are mainly used in a distribution network for electrical power, connecting local substations or small generating units such as wind turbines to the main grid supply point, or for connecting plant in industrial processes which require large amounts of power. Medium voltage insulated cables may also be used in conjunction with bare overhead lines in networks.

Our two leading types of medium-voltage cable are XLPE (cross-linked polyethylene) and EPR (Ethylene Propylene Rubber). The former is used worldwide, while the latter is mainly for selected markets.

From a design point of view, medium-voltage cables are of three types:

- single-core cable,

- three single-core cables laid-up,

- three-core cable.

TYPE OF INSTALLATION

Medium voltage cables can be laid directly in the ground, or pulled into ducts laid in the ground, or run in tunnels or 

above ground on cable trays/ladders.

Cables can be laid in trefoil (three cores arranged in a triangular formation), or flat, dependant upon the actual requirements for each arrangement.
