Product Description

General

The ring cabinet is equipped with manual and electric spring mechanism to operate the vacuum circuit breaker switch, and the ground switch and isolation switch are equipped with manual operation mechanism.

Service environment

• The upper limit of the ambient temperature is +40ºC and the lower limit is -25ºC

• The altitude cannot exceed 1000m

• The daily average relative humidity of air is less than 95%, and the monthly average is less than 90%. The daily mean value of water vapor is not greater than the monthly mean value

• The surrounding air is not significantly polluted by corrosion or flammable gases and water vapor

• No frequent violent vibration

Key Feature

• The ring screen cabinet uses air as the insulating medium

• The inlet and outlet cabinets are equipped with insulating protective partitions interlocked with ground switches
