Structural characteristics

The switchgear is composed of a cabinet, a main switch (a SF6 load switch or a combination device), a ground switch, an instrument room, a bus bar and other electrical components and auxiliary components.

The cabinet is composed of aluminum zinc coated steel plate assembly. The back of the cabinet is provided with a pressure relief channel, so as to protect the operator when an internal fault occurs.

The bus bar of the bus room is covered with an insulating layer and is directly connected to the terminal of the load switch. The three-phase busbar is arranged in longitudinal direction. The switch device can be extended to the left and right, and can be easily changed。

The instrument room is located in the upper part of the switch equipment, and can be installed with the electric current meter, indicator lamp and electric operating mechanism。
