Insulators

Electrical insulator

A high voltage porcelain insulator has a plurality of sheds extending laterally thereof at spaced apart locations therealong. The creepage path length of the shedded insulator is extended by mounting polymeric insulating creepage extenders on the porcelain sheds. The creepage extenders do not extend completely around the periphery of the sheds but leave a gap. Preferably the gaps of adjacent creepage extenders along the insulator are not aligned.

High voltage insulator

The termination of a high voltage electric cable includes a rigid heat shrinkable tube that extends between the cable jacket and a connector mounted on the cable conductor. The tube is made from an engineering plastic material and has a Flexural Modulus and a Young's Modulus high enough so as to ensure that the termination is self supporting. The termination may be used in the transmission of power from one carriage to another of an electric train.
