Power transformer feedthrough 24 - 52 kV, max. 40 000 A | CFPT

high-current

The Type CFPT from TRENCH is a high current bushings that is accessible from 24 kV to 52 kV with a current rating of up to 40,000A in accordance to IEC 60137 standards.The unit is designed to connect an oil filled transformer winding to a generator bus in a duct. The unit is commonly applied in generator step-up transformers.The Resin Impregnated Fiberglass gives high temperature of Class F insulation 155 °C. The active part consists of a solid core, made of fiber glass and inserted concentric layers for the electrical field distribution. The unit is vertically or horizontally mounted which has a partial discharge of less than 10pC at Um. The bushing current rating is guaranteed for transformer oil temperature of 90°C .
