The Insulation Rods are Made of Several Kinds of Insulating Materials
High voltage insulating bar is used for insulating tools operating at short time for electrified equipment, such as connecting or disconnecting high voltage isolating switch, falling fuse and so on. The surface of the insulating rod is smooth, without bubbles, wrinkles or cracks; the bonding between glass fiber and resin is intact; there is a plug at the end of the hollow pipe, and the joints are firmly connected.
The insulation rods are made of several kinds of insulating materials, such as high quality glass cloth, epoxy resin and 306 resin phthalic anhydride, glass fiber reinforced plastic cloth and curing agent. After the first high temperature, the mold was first fixed, and then the mold was removed. After second times of high
temperature grinding, one time rough grinding, two times fine grinding. Then it is made into other FRP products by lacquer, with beautiful appearance, light structure and easy operation. It has excellent mechanical and electrical properties, suitable for all kinds of high pressure conditions, good insulation performance and safe use.
