In the selection of Combined Low Voltage Switchgear products, it is necessary to pay attention to a lot of technical points. Nowadays, there are many varieties and different characteristics in the market. Users often have difficulty choosing. In fact, we can refer to the following points. First, consider the applicable scope of low-voltage power distribution cabinets. Usually, the equipment is small in size, does not occupy much space, and can be used interchangeably in the same model. It has high stability, safety and reliability, and convenient maintenance, so it is widely used. The next consideration is the design requirements of the High Subsection Capacity Low Voltage Switchgear, such as the installation method, the environment around the installation equipment, the nature of the electricity, etc., and then the protection of the equipment switch is considered. The safety of the equipment as the power is the equipment itself. A basic requirement. Finally, it is said that the distribution equipment is intelligent. In today's society, modernization is developing rapidly, and automation and intelligence are the general trend. As an important part of the power grid, power distribution equipment is naturally an important field of intelligent automation construction.
