There are various types of insulators with different shapes. Although the structures and outer shapes of different types of insulators vary greatly, they are all composed of two major parts: an insulating part and connecting fittings. An insulator is a special insulating control device that can play an important role in overhead transmission lines.
[0003] Currently, in order to solve the problem that the steel feet of the spool insulator are exposed and easily wetted by rainwater, resulting in rust, a threaded porcelain cover is fixedly installed at the bottom of the insulator, an adjusting porcelain part is threadedly connected inside the threaded porcelain cover, and then waterproof rings are respectively fixedly installed between the adjusting porcelain part and the threaded porcelain cover and the first steel foot to avoid wetting the steel feet. On the one hand, the existing protection device is fixedly installed at the bottom of the insulator. When the protection device is damaged, the whole needs to be replaced, which will increase the replacement cost. At the same time, the steps of disassembling the insulator at high altitude are numerous and difficult. On the other hand, when the protection device of the existing device is damaged, rainwater can enter the inside of the protection device to wet the steel feet, and the detection and repair of the insulator at high altitude require a certain amount of time. During this process, the spool insulator is extremely likely to rust, thus affecting the performance of the insulator. Content of the Utility Model
