High Voltage Cables are protected by many layers such as the insulation, armouring, shielding, etc. When the cable is to be terminated at a busbar or at an equipment, the insulating and protective layers around it are removed. This leaves the conductor exposed and there is a risk of flash overs and arcing at these spots.
Hence, cables need to be properly terminated to provide electrical and mechanical protection to the conductors at the point of connection.
There are different types of cable terminations such as straight through joints, cold shrinkable types, Heat shrinkable types, etc. Cable joints need to be flexible, have good mechanical strength and chemical and thermal stability.
Cable Termination have frills to increase tracking resistance.
