Product Introduction

GN1-12G(D) series outdoor high voltage isolate switch is the high voltage switch equipment of composite structure, it is suitable for outdoor 12kV line net with voltage and no load to make opening and close. With CS □ type manpower operate machinery, can avoid earth line with power and composite flash-locks, wrong operate. The operator is no need to put another earth line. Pollution-proof type isolate switch satisfy customer in filthy conduction area. It can solve the pollution of shed when it is working.

Definition of model

☆ Outdoor type
☆ Isolating switch

Service condition

1.The altitude above sea level: 2000m.
2.The ambient air temperatures: -40 to 40℃
3.Wind speed doesn't exceed 700Pa (not exceed 34m/s)
4.The earthquake intensity doesn't exceed 8 degrees.
5.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.
6.Pollution proof type isolator applies to sever filthy conduction area. However, it shouldn't be any explosive matters and matters causing fire.
