High and low voltage distribution cabinets are widely used in various fields of production and life, such as schools, organs, hospitals, factories, workshops, families, etc. while professional construction high and low voltage distribution cabinets are generally used on construction sites such as construction sites. Therefore, appropriate products are selected according to different application occasions.

High and low voltage distribution cabinet is widely used in life. High and low voltage distribution cabinet can reasonably distribute electric energy, facilitate the opening and closing operation of the circuit, have high safety protection level, and visually display the conduction state of the circuit. It is mainly used for the control and distribution of electrical equipment, and plays an important role in protecting the short circuit, leakage and overload of the line. Therefore, a high-voltage and low-voltage distribution cabinet with good quality can better ensure personal safety.

1. Shell

Firstly, at present, the high and low voltage distribution cabinets in the market mainly include metal shell and plastic shell, and the structure includes concealed type and exposed type. Therefore, when selecting, select according to the actual needs. No matter which type of high and low voltage distribution cabinet is selected, the box must be intact, and the door panel of high and low voltage distribution cabinet shall have inspection transparent window.

2. Model size

In the domestic power supply and distribution system, there are many models of high and low voltage distribution cabinets, and their box structure and technical parameters are different. According to the different application occasions, there are many sizes of high and low voltage distribution cabinets, and the prices also vary greatly.

3. Bus bar

The wiring busbar in the high and low voltage distribution cabinet box shall be set with change, protective grounding wire and phase wire respectively, which shall be intact and have good insulation performance to ensure the safety of daily use.

4. Install the seat frame

The mounting base frame of air switch shall be smooth and have enough space.

5. Load

According to the load nature and purpose, the high and low voltage distribution cabinet shall be determined as lighting high and low voltage distribution cabinet or power high and low voltage distribution cabinet or socket box. According to the magnitude of load current, voltage level and protection requirements of control objects, determine the capacity and voltage level of switchgear and protective appliances of main circuit and each branch in high and low voltage distribution cabinet.
