One of the characteristics of low-voltage switchgear is the multi-functional busbar system.

                                     The importance of busbar systems in low-voltage switchgear

The bus bar is a conductor that connects large electrical equipment such as generators and transformers with various electrical equipment. The role of the bus bar is to transmit electric energy from the ash machine and the division, and the bus bar is the main equipment that constitutes the electrical wiring. Today, Wiener Electric will tell us about the key points of the main bus in the low-voltage switchgear.

At present, special-shaped main buses are widely used in low-voltage switchgears, such as "I" shaped main buses are selected in MNS rear outlet cabinets. The key points of the main bus in the low-voltage open light cabinet are:

1. Focus on improving the bending strength of the bus system and improving the ability of the main bus to resist short-circuit current;

2. The non-porous connection between the branch bus and the main bus bar is selected, which simplifies the installation method of the bus system. At the same time, the branch bus and the drawer circuit also choose the plugging method without punching, which is convenient for the use and protection of the low-voltage switchgear.

The bus system is an important part of the low-voltage switchgear. The bus system determines the electrical parameters such as the thermal stability of the low-voltage switchgear, the inlet and outlet methods of the low-voltage switchgear, the connection method of each main circuit, and the heating of the low-voltage switchgear.
