GW9-40.5 Outdoor disconnector （isolating switch）40.5kv
The material selection of the GW9-35 isolation switch is also very particular. The structure of stainless steel shaft pin and oil-free self-lubricating bearing is matched, and the steel parts are hot-dip galvanized to ensure the operation of the isolation switch is flexible, lightweight and reliable, and can effectively prevent rust 3.
GW9-35 isolation switch is suitable for high pressure environment such as 35KV wind farm, its specification is GW9-35(40.5)KV-630/1250A,the product has the ability to automatically clean contacts to improve contact reliability, and the rotating part is designed as a maintenance-free structure to ensure long-term stability and reliability.
