3M™ ThermaVolt AR Electrical Insulation Paper

Overview: 

3M™ ThermaVolt AR Electrical Insulation Paper

3M™ ThermaVolt AR Electrical Insulation Paper combines the best of two technologies – inorganic and aramid – to offer the excellent thermal conductivity and voltage endurance of inorganic insulation plus the strong mechanical and thermal properties you expect of aramid insulation.

3M™ ThermaVolt AR (TVAR) Electrical Insulation Paper is a significant advancement in the development of electrical insulation used in electrical equipment, such as dry type transformers and motors. This premium-performance insulation is a cost-effective alternative to higher temperature insulation materials.
