Introduction of inner fiber and outer plastic:
Silicone rubber glass fiber sleeve is made of non-alkali glass fiber woven tube, extruded silicone rubber, vulcanized by heating. This kind of casing has excellent dielectric property, high heat resistance and excellent cold resistance, softness and elasticity, and is also widely used in wiring insulation and mechanical protection of class H electric machinery and special electrical appliances.
