Product Description
7KV silicone rubber fiberglass sleeve for electric motor winding
Description:
Silicone rubber fiberglass sleeve is made of alkali-free fiberglass woven into a tube, coated with a layer of silicone rubber composite material on the outer layer of the tube, and then heated and cured. With high dielectric strength, good flexibility, heat resistance aging, flame retardant, temperature resistance up to 200ºC.
Widely used in household electrical appliances, motors, electromechanical equipment, vehicles, ships and other circuit insulation protection.
