Power transformer components

Insulation components made from pressboard - such as angle rings (segments), chimney segments, and molded parts in the expelling area - allow optimal adaptation to the electric field conditions in the transformer. Our insulation components are suitable for use in oil-filled power transformers due to their high purity, mechanical strength, and ability to be impregnated with oil. 

Our insulation components are produced using special processing procedures, which guarantee high compaction and dimensional stability. The excellent mechanical properties of the insulation material provide the required safety in the event of a short circuit.
