A switchgear is an electrical installation that serves to receive and distribute electricity and contains switching devices, busbars and connecting buses, auxiliary devices (compressor, battery, etc.), as well as protection devices, automation and measuring instruments.

Switchgears of electrical installations are designed to receive and distribute electricity of the same voltage for further transmission to consumers, as well as to supply equipment within the electrical…
