GW1-24 series three pole outdoor disconnector with fuse-bases is the high voltage
switch equipment, in the suitable for outdoor 24kV line internet with voltage and no
load, to make separate and fabricate. With CS8 type manpower operate machinery,
to avoid earth line with power and composite flash-locks etc wrong operate. The
operator no need put another earth line. Pollution-proof type isolate switch of
customer in filthy conduction area. It can solve the pollution of shed when it is work.

The altitude above sea level: 2000m
The ambient air temperature: -40℃~40℃
Wind speed does not exceed 35m/s.
The earthquake intensity does not exceed 8 degrees.
The working situation is without frequent violent vibration.
The installation site of ordinary 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.
Pollutioni-proof type isolator is applies to severe filthy conduction area, however,
it shouldn't be any explosive matters and matters causing fire.
