Main Structure The main structure adopts 8FM opening section steel, in both sides of which there are two mounting holes with modulus 20mm and 100mmφ9.2mm respectively. The internal mounting is flexible and convenient. The main structure has two alternatives of mode of assembly, i.e. fully assembled structure and the structure with welded part frames and beam. All the function chambers of the cabinet are separated. The compartments include a functional unit chamber, a bus chamber and a cable chamber. All the chambers are independent relatively. The horizontal main bus bar is arranged horizontally on the cabinet back for the purpose of enhancing the bus’s capability of resisting electromotive power. This is a basic measure to make the main circuit have a high short circuit withstand strength. The design of cable compartment enables the cables to pass through upwards or downwards to be extremely convenient.

Electrical panels Functional Units
The course height of drawer is 160mm, including such five dimensions as 1/2 unit, 1 unit, unit, 2 units and 3 units. The rated current of unit circuit is up to and including 400A. The modification of drawer is generally made to the height but not to that of width and depth. The drawers with same fictional units are interchangeable. Each MCC cabinet is able to mount 11 1-unit or 22 1/2-unit at most. The incoming and outgoing lines of drawer adopt the chip structure socket connectors with different number of chips but same specification according to the current intensity. The drawers of 1/2 unit are switched to the cable chamber by means of the ZJ-2 type switch parts of back plate type structure. The unit drawer is switched to the cable chamber by means of bar or tubular ZJ-1 type switch parts of the same size according to the classification of current. There are obvious marks in the positions of separation, closing, test and drawing out in the drawer panel. The drawer unit is equipped with a mechanical interlocking device.
