Overview:
According to the type of switch, it is divided into load switch with grounded assembly (referred to as C module),
load switch without grounded assembly (referred to as CB module), circuit breaker with grounded assembly (referred to as V module),
circuit breaker without grounded assembly (referred to as VB module), circuit breaker contact switch (referred to as VZ module),
Load switch + fuse combination electrical switch assembly (referred to as F module), isolation switch assembly (referred to as G module).

What is high-voltage gas-insulated switchgear?
Gas-insulated high-voltage switchgear (GIS) is a compact metal encapsulated switchgear consisting of high-voltage components
such as circuit-breakers and disconnectors, which can be safely operated in confined spaces.
Environmental Conditions of SF6 gas insulated switchgear
1)Suitable Temperature: -15℃~ +40℃
2)Suitable Altitude:≤1000m
3)Relative Humidity: Daily mean≤95%, monthly mean≤90%
4)Gradation of Earthquake Damage:≤Level 8
5)Applicable occasions should be free from corrosives, inflammables and vapor.
