GW5 Series Outdoor Ac High Voltage Disconnect Switch
GW5 series outdoor disconnect switch is the most common equipments in electric system. Its main function is isolating high
voltage when the equipments or circuit do the maintenance, to ensure safety. GW5 cannot break the load current and short-
circuit current,need to use cooperatively with circuit breaker. When power cut firstly separate breaker then separate disconnec
switch; when power on firstly close disconnect switch, then close breaker.
GW5 series outdoor disconnect switch belong to double column V shape,horizontal open-type.Each single stage
composed of substrate,supporting insulator,outlet power,contact,etc. It fixed by two 50° included angle substrate,supporting
insulator and two supporting insulator make the angle to each other,and install the bearing of substrate,vertical with substrate.
Leading electric part separate instal on the two supporting insulator,make the 90° rotate together with the supporting insulator.
