The GW4A-40.5 isolating switch produced by our company has a double-column central breaking structure. It is a product that has been improved in accordance with the regulations of the State Grid Corporation of China.

 

 

1.Good electrical conductivity. It adopts self-operated contact fingers, and the ends of the contact fingers are fixedly connected to avoid overheating caused by poor contact.

2.Good sealing. The bearing seat adopts a fully sealed structure with two seals. It is filled with grease during assembly and does not need to be filled with oil during use. Rain and moisture are isolated, and the grease will not be lost or solidified. Solved the problem of bearing rust due to lack of grease.

3.Avoid rust. All shaft pins are made of stainless steel to maintain long-term operational flexibility.

 

4.Maintenance-free. The operating mechanism shell is made of stainless steel plate and the gear box is fully enclosed.
