Low voltage distribution panel, switch cabinet, switch board, lighting box and power box. There are mainly high-voltage fuses; High voltage disconnector; High voltage load switch; High voltage circuit breaker.

The section of power system from the outlet of step-down distribution substation (high-voltage distribution substation) to the user end is called distribution system. It is composed of a variety of distribution equipment A power network system composed of (or components) and distribution facilities that converts voltage and distributes electric energy directly to end users. It can be divided into three parts: high-voltage distribution system, medium voltage distribution system and low-voltage distribution system. It is a widely used charging method. Telecommunications devices, uninterruptible power supply (UPS) The floating charge and trickle charge of the battery are constant voltage charging. The starting battery is also charged at approximately constant voltage when the vehicle is running. The utility model has the advantage that the charging current can be automatically adjusted with the change of the state of charge of the battery

1. The sheet metal electric control cabinet and electric control cabinet products in traditional industries have poor and thin plates, and the paint is easy to fall off, which is easy to cause rust and decay, short service life and unsightly.

2. The product design of domestic traditional sheet metal processing is unreasonable, the use process is not humanized and the functions are not complete; The design of Hoffman's new cantilever and outdoor cabinet is reasonable, which combines humanization and practicality;

3. The quality of traditional products is not enough. Iron products and surface treatment with general quality are easy to cause rust erosion. Blindly pursuing low cost leads to Jerry built materials and thickness, which is easy to deform over time; The Hoffman cantilever control box is made of aluminum material, which has the advantages of light material, corrosion resistance, good color and stable structure;

4. The traditional design is not beautiful enough, but the modular design of Hoffman cantilever control box uses the splicing and assembly of aluminum profiles and aluminum die-casting corner parts to replace the traditional welding and grinding. The anodized aluminum profile on the surface is easier to wipe and always keep the cantilever bright as new;

5. Compared with imported parts, our quality has reached a considerable level, and we have very significant advantages in price and delivery time; At the same time, our products are more comprehensive. Combined with the actual use needs of customers at home and abroad, we design more products for customers to choose and use.
