General
(H)GW8 outdoor high voltage disconnector is a single phase AC switching device for 50 to 60 Hz high voltage. It is use for breaking transformer neutral point earthing when there is voltage but without load in the power system with the maximum voltage of 126kV.
The product is divided two types: ordinary and anti-dirt (W) type.
The CS8-5 manual-operated device mechanism or CJ6 motor-operated device mechanism can be cooperated with the disconnector.
