An anti-bending wall bushing comprises a conductor and an insulating layer from inside to outside. The insulating layer is wrapped by an umbrella skirt, the two ends of the conductor extend out of the insulating layer, voltage-sharing caps are arranged at the two ends of the insulating layer, a flange is arranged in the middle of the insulating layer, and the insulating layer is made of high-voltage electric porcelain. Due to the fact that the insulating layer is made of the high-voltage electric porcelain, insulating performance of the product is guaranteed, and high bending strength is achieved.
Description
technical field [0001] The invention relates to electrical equipment, in particular to an outdoor high-voltage wall-piercing bushing. Background technique [0002] High-voltage wall bushings are used in power distribution devices and high-voltage electrical appliances in power stations and substations, for wires to pass through grounding partitions, walls or electrical equipment enclosures, and to support conductive parts to insulate them from ground or enclosures. In the prior art, the insulation layer of the wall bushing is generally made of polytetrafluoroethylene, which is excellent in insulation and corrosion resistance, but poor in bending resistance. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a wall-piercing bushing with strong bending resistance and insulation performance. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a bending-resist...
