Shunt reactor insulation

Choke windings in shunt reactors require similar insulation components to power and distribution transformers. These are manufactured from pressboard and used for insulation, cooling channels and for mechanical support in compensating chokes.

Our pressboards stand out for their high quality, high purity, mechanical strength and optimum oil impregnability. The excellent mechanical properties of the insulation material provide the required safety in the event of a short circuit.
