The material used to manufacture the low-voltage cable branch box is a resin-based composite material. The main composition of the box is divided into ABS engineering plastics, polycarbonate transparent PC material, DMC, SMC four materials injection molding and pressing.
What is a meter box?
Features of the meter box:
1. Thoroughly solve the personal injury and death accidents caused by poor grounding of the cabinet and overlap of foreign objects;
2. The comprehensive use cost is low, and the one-time investment can be used for more than 20 years (avoid metal box replacement work hours and cumulative costs);
3. The unique design of the box can effectively resist the impact of external forces;
4. The material recovery cost of the cabinet is relatively high, which can prevent the body from being stolen;
5. The splicing method can reduce the maintenance cost of the cabinet (only the damaged parts can be replaced);
6. Burning at high temperature does not produce suffocating gas
Working principle of the meter box
The power distribution box is to assemble the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements to form a low-voltage power distribution device. During normal operation, the circuit can be turned on or off by means of a manual or automatic switch. In the event of malfunction or abnormal operation, the circuit will be cut off or alarmed with the help of protective appliances. The measuring instrument can display various parameters in operation, and can also adjust certain electrical parameters, and prompt or signal deviations from normal working conditions. Commonly used in various power generation, distribution and substations.
Application of meter box
Cable branch boxes, low-voltage distribution boxes, water pump control boxes, communication device cabinets, street lights and traffic light control boxes, multi-function metering boxes, integrated distribution boxes, capacitor compensation boxes, terminal boxes, and wall-mounted distribution boxes in public power grids , Metering box, etc.
