GSM is an air insulated (AIS), metal enclosed, switchgear cubicle. It is  suitable for electric distribution automation and compact also expandable metal close switchgear. It characters in its simple structure, flexible operation, reliable interlocking and convenient installation etc., which can provide the satisfactory technical projects both for different application occasions and users.

Service environment:
a) Air temperature:Maximum temperature: +40ºC; Minimum temperature:-25ºC
b) Humidity:Monthly average humidity 95%; Daily average humidity 90% .
c) Altitude above sea level:Maximum installation altitude: 2500m
d) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
e) No frequent violent shake

With the adoption of sensor technology and the protection relay up to date, plus the advanced technology and flexible assembly project, GSM can completely meet the requirement of continuously variable market.

GSM can take SF6 load break switch; also according to user's demand can be assembled with the vacuum circuit breaker. Operational methods  can be either manual or motor driven.
