Within the plastic, fiber tube: inner plastic, fiber casing silicone rubber-based extruded into a tube, and then the glass fiber braid, then dip made of heat-curing silicone resin. Due to the inclusion of silicone rubber and glass fiber, it has excellent heat resistance and dielectric properties, it is widely used in a variety of high-voltage electrical insulation protection.
