How to judge the quality of a power distribution cabinet?

1. Shell thickness and material. The thicker the shell is, the better it is to resist moisture and high temperature, it is not easy to deform, and it is easier to protect electrical components.

2. Air switch quality. Different models of the same number have different durability. The larger the model, the higher the durability, and the more conducive to extending the life of electrical components.

3. Copper bars. The cross section, thickness, and material of the copper bars are different, and the resistance is also different. Compared with brass galvanized, medium and low-grade copper galvanized, high-grade copper galvanized has lower resistance and more stable current.

4. Wiring layout. The neat and uniform wiring layout is more beautiful and practical, which is more conducive to the operation of electrical operators.

5.3C certification. Professional and authoritative testing and compliance with national 3C certification can ensure quality.
