Many types of electrical apparatus require functional components that demonstrate resistance to high temperatures (over 200 °C) for long periods of time. Certain non-cellulose materials provide this capability as well as other desired characteristics such as dimensional stability and dielectric strength. Appropriate use of these materials will ensure the mechanical and electrical integrity of the apparatus.
Field of Application
In the electrical sector, use of high temperature boards is typically required in dry type transformers, fluid filled transformers expected to operate at higher than normal temperatures (examples are mobile transformers and furnace transformers), traction motors, generators, and switchgear.
