explosion-proof illumination (power) distribution box

1. it is widely used in flammable and explosive gas environment such as oil exploitation, refining, chemical industry, offshore oil platform, oil tanker, etc. it is also used in flammable dust places such as military industry, port, grain storage and metal processing;

2. applicable to zone 1 and zone 2 of explosive gas environment;

3. applicable to iia, iib, iic explosive gas environment;

4. applicable to areas 21 and 22 of flammable dust environment;

5. applicable to the temperature group is t1 ~ t4 / t5 / t6;

6. for the distribution of lighting or power lines, electrical equipment on-off control or inspection and maintenance distribution.

model implication



1. the outer casing of the product is cast aluminum alloy zl102. adopting one-time die-casting process, the surface is smooth, the appearance is beautiful, the internal structure is high in density, the impact resistance is strong, and the explosion-proof performance is good. there is a permanent “ex” explosion-proof mark on the product.

2. after the surface is removed by industrial robots and high-speed shot blasting, the advanced automatic high-pressure electrostatic spray and heat-curing line process is adopted to form the plastic layer adhesion on the surface of the shell. strong, the product's anti-corrosion ability is good.

3. the component cavity adopts explosion-proof explosion-proof structure with a wall thickness of 12mm, and the inlet and outlet chambers adopt an increased safety explosion-proof structure. modular combination between the cavities, the explosion-proof chambers are not in phase bypassing, the net volume of a single cavity is reduced, thereby eliminating the overlap of the explosion pressure and enhancing the explosion-proof performance of the product.

4. adopting the patented technology of the combined explosion-proof distribution box independently developed by the company, the modularization optimization design and combination of the distribution box can be arbitrarily combined according to the requirements. configuration requirements for power distribution equipment in different locations.

5. the sealing strip adopts two-component polyurethane primary casting foaming process with high protection performance.

6. there is a special operating mechanism on the cover to achieve full-close operation. padlocks can be added according to requirements to avoid misuse.

7. the main switch and sub-switch operation panel are clearly distinguished, which is convenient for on-site identification.

8. all exposed fasteners are made of stainless steel.

9. cable in and out of the line, according to user requirements can be made up and down, down and down, up and down, down and up and other forms.

10. the inlet and outlet ports are usually made of pipe threads, and the cable clamping and sealing device is arranged. it can also be made into metric thread, npt thread, etc. according to the requirements of the user's site.

11. steel pipes and cable wiring are available.

12. for outdoor use, the rain cover can be configured according to user requirements.

13. the installation method of the distribution box is generally hanging type, and it can be established, seat type or power distribution cabinet when special requirements.

main technical parameters


order note

1. when ordering, number of circuits, the corresponding current and circuit breaker poler number are necessory if it is with leakage function, please indicate its current and poles and ways, size and quantity of inlet and outlet;

2. user must supply electrical diagram generally. our company can design the best solution according to the user's requirements and confirm it and produce it.
