5.       Construction

The basic structure of the switchgear panel comprises the panel itself and withdrawable part.

The panel is constructed by bolting together. Enclosure and internal partition are of anticorrosive steel sheets. The panel consists of four separate compartments, that is truck compartment, busbar compartment, cable compartment, low-voltage maintenance type, double-face maintenance type. Withdrawable part can be classified by function to:

VCB truck

PT truck

Disconnect truck

Metering truck

HV fuse truck etc.
