| Rated current: 400A-4000A |
GW4-11, 24, 35, 40.5, 72.5, 126 series outdoor AC high voltage isolating switch. It is suitable for power systems with a frequency of 50Hz and rated voltages of 11, 24, 35, 40.5, 72.5, and 126kv, and is used as a circuit breaker when the voltage is no load. Among them, the anti-pollution isolating switch can meet the requirements of users in heavily polluted areas, and can effectively solve the problem of pollution flashover in the operation of the isolating switch.

Using the environment conditions
a. The altitude does not exceed 1000m.
b. The ambient air temperature: Maximum+40°C; Minimum: -30"C,Paramos-40°C.
c. The wind pressure does not exceed 700Pa. (corresponding to 34m/s wind speed).
d.
The earthquake intensity does not exceed 8 degrees..
e. The working situation hasn't frequent violent vibration.
f. The installation site of ordinory type isolator should be kept away from gas, smoke chemical deposition, salt-spray fog, dust and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator.
g. Pollution-proof type isolalor is applying to severe filthy conduction area; however, it shouldn't be any explosive matters and matters causing fire.
