The enclosure is made of aluminium-zinc plated steel sheet by CNC machine, high precise dimension, short production cycle, excellent mechanical strength and nice appearance. The busbar compartment, VCB handc art compartment, cable compartment and relay compartment are separated by metal sheet. Flexible operation for handcart movement, clear position instruction, the earthing switch allow to making short circuit current and creditable mechanical interlock.
