Factory Supply Medium Voltage 11kv gang isolator GW1-12

GW1-12 HV Disconnect Switch
GW1 outdoor AC high voltage disconnect switch (disconnect
switch for short)is used to open and close circuit with voltage
but no-load 50/60HZ, 12(40.5)kV power system. It accords
with standard: IEC129-1984 AC Disconnect Switch and
Earthing Switch.
There are with earthing and without earthing two types,
for earthing type, it can be matched with CS type manual
mechanism to avoid error, there is no necessary to hang
an earthing line. There are normal and anti-pollution two
types, the anti-pollution type used in serious pollution area.
Structure feature
This disconnect switch consists of three single pole switch,
each single pole switch have same structure, frame,
operating insulating, static contactor, blade, etc, for with earth
switch, It can matched with CS operating mechanism,
for no earth switch, it can matched with CS8-5 operating
mechanism accordingly. When without circuit breaker or
circuit breaker was fault, disconnect switch can opening and
closing under the condition:
C/O voltage transformer which for metering,
C/O charging current which on busbar facility,
C/O power transformer no load current (power transformer
capacity should less than 750kVA).
