Electrical power cable terminations
The electrical cable termination is the physical and electrical connection of a cable end that connects to another cable, or to the terminal of the equipment. The cable terminations are often designed to enable the physical and electrical interconnecting of two cable ends, or a cable end and a terminal on the equipment.
The electrical connection requirements relate to the voltage drop, current carrying capacity, compatibility of the materials, etc. The physical requirements relate to the environmental protection as well mechanical security.
The methods used to terminate the cables vary according to the type of cable, type of connector and application. The common type of terminations are crimp connection, soldered connection, compression termination, and wire-wrapping connection, direct connection, loop or eye connection. Some of the factors that determine the type are:
Outdoor or indoor use
Voltage
Current
Overhead, or underground
Type of Connector on the equipment where the cable will be connected.
Using cold shrink cable terminations reduces the risk of cable jointer error or inflicting damage to medium/high voltage cable insulation, including XLPE and EPR. The cable terminations are compact and easier to use in enclosed areas or confined space switchgear and cable boxes typically distributing 11kV/33kV electricity.
Cold shrink does not require any cooling down time before the cable can be energized unlike heat shrink cable terminations.
