Product Features

1.XGNẞ-12 switchgear uses sealed metal box-type structure, and the framework of cabinet is welded by angle steel and steel sheet.

2.The cabinet is divided into circuit breaker compartment, busbar compartment, cable compartment and relay compartment,separated by steel plate between two compartments.

3.The switchgear was set by a front and a back door. And it is installed away from the wall and could be maintained from both sides.4.A pressure relief channel is provided at the top of thecabinet. If internal arcing fault occurs, it is able to release pressure anddischarge gas from the pressure relief channel to ensure the safety of operators.

5.The switchgear has a perfect “five-preventions”, with simple and clear operation procedures.

6.The main circuit breakers that the switchgear using are ZN28- 12, ZN63A, VCA, etc. series vacuum circuit breakers; and othertypes of circuit breakers can also be used according to the requirements.

7.The disconnecting switch is GN30 rotating disconnecting switch or GN22 big current disconnecting switch.
