GN30-12(D) series Indoor high voltage disconnecting switches

Description

GN30-12(D) series Indoor high voltage disconnecting switches is a new type of touch rotating knife isolator , which special designed for XGN2-12 HV switchgear, with rated voltage 12kV and three phase AC 50Hz indoor device. It’s mainly used for making and breaking circuit under with voltage and no load.

Its main structure in three-phase chassis of the upper and lower two plane, fixed two set of insulator and contact, by rotating contactor, so as to realize switching on & off.

Environment condition

- Ambient temperature: max. +40°C min. -25°C

- Altitude: ≤1000m

- Wind pressure: ≤700Pa (equals to wind speed 34m/s)

- Relative humidity: daily average ≤95%, monthly average ≤90%

- Earthquake intensity: ≤8 degree

- No corrosive, explosive or flammable gas ,no violent vibration
