Lighting pole top box equipment is the equipment responsible for the control, protection, conversion and distribution of electric energy at the end of low-voltage power supply system. It is mainly composed of wires, components (including disconnectors, circuit breakers, etc.) and boxes.

 

The structure of lighting pole top box has the following characteristics:

 

1. Mature technology: simple principle and important components: various switching components, shell, transparent door, upper cover, zero row, protective grounding row, insulated conductor, etc.

 

2. It has various protective devices against electric leakage, electric shock, short circuit, overload and so on.

 

3. The surface of the cabinet adopts epoxy powder electrostatic spraying, which is uniform and beautiful, conducive to anti-corrosion, strong adhesion, good texture and comfortable appearance. The internal structural parts adopt galvanizing process and have certain anti-corrosion ability.

 

4. Incoming line mode: the upper, lower, left, right and back of the box can be provided with incoming line knockout holes to facilitate wiring.

 

5. The components in the cabinet are low-voltage appliances of famous brands at home and abroad. The product has good stability.

 

6. Safety: the cabinet type is indoor closed distribution cabinet, which adopts special profile assembly structure, and the shell adopts cold-rolled steel plate with thickness of 1.2mm, which has the characteristics of light weight and high strength. The plastic small door is made of fireproof resin material, which can effectively prevent the spread of fire. It is installed on the standard guide rail. It can be combined arbitrarily according to the needs, which is convenient for disassembly and assembly. The handle of the switching element is exposed, and the live part is covered inside the upper cover. It is convenient to open the door.

 

7. The box door is connected with the PE point in the box with multi strand flexible braided wire, and the whole box structure forms a continuous protection circuit.
