Features of the Structure
The basic framework of the RGCK, RGCL is joint-installed structure.
All the pieces of the framework are zinc plating and processed by
spraying plastic. Screws to form the framework tightly connect
them. After the components including the upper door, the back
plate, the isolation board, the drawer, the installing supporter,
the bus bars and the electric units etc. Are added according to the
need, a complete controlling center board is finished. The
structural features of this board
Are listed as follows.
4.1 Shelves of the Board
The shelves of the board adopt special section. They are located by
using the angle plate and are connected by screws
Without welding structure.
A. Modularization is carried out on the molding size and aperture
size of the components and the intervals between the devices. (The
module E is equal to 20mm, which is also available in the following
B. The inside structural components are zinc plating.
C. The surface receives phosphate treatment and electrostatic epoxy
D. The framework of the board is divided into three isolated areas
bus bar house, function unit and cable house. This prevents the
accident from being enlarged and brings convenient fixing with
