Product features:

　　*Cabinet structure:The ring main unit cabinet is made of 2mm corrugated aluminum zinc plate and riveted.There are two pressure release points on the back panel of the cabinet,one for the cable room and the other for the load switch/busbar room.This structure can maximize personal safety and ensure the reliability of equipment operation.

　　*Each compartment:The busbar compartment is located at the top of the cabinet and connected to adjacent switchgear;Mechanism chamber and coupling:The chamber includes the operating mechanism and mechanism coupling,as well as position indication,auxiliary contacts,trip coils,live displays,and couplings;Low voltage box:The low voltage box is located at the top of the cabinet and is optional;Circuit breaker room:A circuit breaker can be placed below the load switch.

　　*Pressure release:The pressure release above is used to release the gas pressure generated during internal electrical accidents in the busbar and load switch room;The following pressure release is used to release the gas pressure generated during isolated accidents inside the cable compartment.
