Description:
HGW1-12G series outdoor high-voltage isolating switch is a new type of switch designed by our company for the original HGW1 switch. It is designed according to the current national standards and international standards.
The switch itself has a grounding knife gate, which can effectively prevent the wrong operation such as "carrying the grounding wire and closing the grounding wire", and the operator does not have to attach another grounding wire.
The product has excellent electrical and mechanical properties, and has fully met the requirements of the national standard GB1985 and its first revision and the international electrical standard IEC129.IEC694. It is the replacement product of the current 12kV class isolation switch.
Use environment:
a. The altitude does not exceed 1500 meters
b. Ambient air temperature: upper limit +40 ° C, the lower limit is generally -30 ° C
c. The wind pressure does not exceed 700pa (equivalent to wind speed 34m / s)
d. The seismic intensity does not exceed 8 degrees
e. No frequent and severe vibrations
f. Ordinary installation sites shall have no gas, vapor, chemical deposits, salt spray, dust and other explosive or aggressive substances that seriously affect the insulation and conductivity of the knife switch. The anti-fouling type is suitable for heavy pollution areas, but should not cause fire and explosive substances
