Silicone Fiberglass Sleeve is made of E-glass fiber by weaving, and immersed in silicone resin, then dried by heating. It possesses high property of electrical isolation and wide range of temperature-resistance. Its temperature-resistant range is from - 30℃ to + 200℃, And its breakdown voltage could be from 1200 V up to 7000 V according to demand. And, it is widely used for H-grade electrical isolation at the output part of electrical motors, transformers, and high-voltage electrical apparatus; and also used as protection in some electrical equipment, of which the high temperature is easily occurred.
