PRODUCTS DETAILS

GW5 Series Outdoor High Voltage Disconnector

General:

GW5 series outdoor  high voltage disconnector is a three phase AC switching device for 50 to 60HZ high voltage. It is used for breaking the circuit when there is voltage but without load in the power system with the maximum voltage of 40.5Kv 72.5Kv or 126Kv.
According to the usage, the product is divided into ordinary, anti-dirt and special types. The special type is futher divided into three types, which are mounthed in a side, up-side-down or inclining way, so the mounting is flexible.
The earthed switching part of the product has two ways of earhing, ie. single or double earthing. The earthing switch has a structure of type I or type II and the electric paramters of the type II earthing switch has the same short-circuit withstand ability as the disconnector switch.
The product is provided with a manual or motor operating device and an electromagnetism lock can also be fitted to prevent from wrong operation. The exposed parts are all made of stainless steel or processed with aluminum alloy processing technology or hot-zinc-plating technologt to ensure operation with no corrosion for a long period of time, and further ensure the flexibility and relability of the prduct, satisfy the requirments in the different areas.
