Glass insulator

Glass insulator 

As shown in the right picture, it is generally a light green glass insulator, which is used on the electric pole. It is fixed to the channel steel and angle steel through connectors such as D-type iron, insulator spindle, and round eye bolts. It is used to fix the wire to the pole and insulate the wire from the pole. It is one of the key accessories of high-voltage transmission lines. Its performance directly affects the operation safety of the entire transmission line. It is widely used because of its zero value self-breaking and easy maintenance. It can be seen everywhere.

Type distinction

Glass insulators are divided into ordinary models and anti-fouling models. The anti-fouling model is relatively more expensive than the ordinary model, has high anti-fouling performance and long service life. In use, the model size is determined according to the size of the creepage distance. Common and general models are: U40B/BP, U70B/BP, U120B/BP, etc., and can also be selected according to the creepage distance. Fixed creepage distance corresponds to fixed model.

For example, model U70B/146 means that the insulator has an electromechanical breaking load of 70kN, and 146 means that the structural height is 146mm.

How to choose

First, choose according to the model, choose according to the creepage distance, and choose whether to use a normal model or an anti-pollution model according to the scene you need.

Second, the model and quantity determine the price. There are many refurbished insulators on the market now, and the price may be lower than the factory price, but you must pay attention to the difference.

We are an insulator manufacturer and can provide a large number of insulators, guaranteeing quality and ex-factory prices. You can come to the factory to check. At the same time, we have our own familiar logistics company and provide logistics (container) services. If you want to know more or are in urgent need of or short of glass insulators, please leave your contact information and we will provide you with professional and efficient services!
