Abstract

The basic structure of the cabinet is assembled from C-shaped profiles. The C-shaped profiles are made from steel plates bent with a modulus of E=25mm for the mounting holes.

1: The basic structure of the cabinet is assembled from C-shaped profiles. The C-shaped profiles are made of steel plates bent with a mounting hole modulus of E=25mm.

 

2: The pull-out MCC cabinet is divided into three compartments: the functional unit compartment (on the left side of the cabinet), the busbar compartment (at the back of the cabinet), and the cable compartment (on the right side of the cabinet). Since the horizontal busbar compartment is at the back, it can also be made into a double-sided cabinet.

3: To reduce the width required for placing the switchgear, the main busbar of the switchgear is installed horizontally at the top of the switchgear, with the back half being the cable compartment. At this moment, it is similar to the busbar style of GCK cabinets.
