High-voltage metal-enclosed switchgear

High voltage metal enclosed switchgear is a combined electrical appliance, which can collect circuit breakers, composite switches, contactors, disconnectors, fuses, mutual inductors, lightning arresters, capacitors, buses and corresponding measuring devices, control devices, protection devices, monitoring and diagnosis devices, signal devices, interlocking devices, etc.

There are many types of high-voltage metal-enclosed switchgear. Generally speaking, there are four main types:

1. Air-insulated high-voltage metal-enclosed switchgear;

2. Gas-insulated high-voltage metal-enclosed switchgear (C-GIS)

3. Ring main unit (RMU)

4. High voltage load switch-fuse and fuse-contactor cabinet (F-C)
