Performance Index
The design of the device meets the following criteria
IEC439-1 Low-voltage switchgear and control equipment
GB7251 Low voltage switchgear
ZBK360001 Low voltage withdrawable switchgear
Primary Structure
• The main frame is made of 8MF open section steel, and the two sides of the section steel have installation holes with modules of 20mm and 100mm and Φ9.2mm respectively, making the internal installation flexible and convenient;
• The main frame assembly form is designed in two ways, full assembly structure and part (side frame and beam) welded structure, for users to choose;
• Each function room of the device is isolated from each other, and its compartment is divided into function unit room, bus bar room and cable room. The function of each chamber is relatively independent;
• The ice flat main bus line is arranged in a flat mode behind the cabinet to enhance the ability of the bus to resist electric power, which is the basic measure to make the main circuit of the device have high short-circuit strength;
• The design of the cable compartment makes it very convenient for the cable to enter and exit.
• Size of universal cabinet (see table below)
