High Current Bushings CFPT are available from 24 kV to 52 kV with a current rating up to 40 kA. Typical applications are generator step-up transformers (GSU).
The performing technology of Resin Impregnated Fiberglass provides high temperature withstand (Class F insulation 155 °C). No current limitation when the Bushing is operated under temperature up to 70 °C in a bus-duct and transformer oil temperature of 90 °C. The design of the Trench High Current Bushings facilitates the interchangeability with the existing units. Available with porcelain or composite insulator on air side with the same dimensions.
