Detailed Product Description

GW4-40.5 outdoor high voltage disconnector is a three phase AC switching device for 50 to 60Hz high voltage. It's used for breaking the circuit when there is voltage but without load in the power system with the maximum voltage of 40.5kv.

The structure of the earthed swithcing part is divided into 3 types: no earthing,single or double earthing. It can also be divided into two type according to eareas in which it is uses: ordinary or anti-dirt type.The earthing swith has a structure of type I or type II and the electric parameters of the type II earthing switch has the same short-circuit withstand ability as the disconnector switch.

The product is provided with manual operating device and a electromagnetism lock can also be fitted to prevent from wrong operation,
