explosion corrosion-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 corrosive gases, moisture, and high protection requirements place;

6. applicable to the temperature group is t1 ~ t6;

7. perform overload, short circuit and protection on the controlled circuit and make separate points lighting (power) switch for branch lines.

model implication



1. the switch cavity adopts an explosion-proof structure, and the inlet and outlet chambers adopt an increased safety structure. the modular combination between the cavities, the cavities are not connected to each other, reducing the net volume of the single cavity, thereby eliminating the overlap of the explosion pressure and enhancing the explosion-proof performance of the product; each circuit can be freely selected and assembled; small size, neat, beautiful, occupying less space on site; light weight, easy to install and maintain.

2. the outer casing is welded by stainless steel plate. the product has strong anti-corrosion ability and impact resistance, and the outer casing has good explosion-proof performance. the product is laser-engraved into a permanent “ex” explosion-proof mark.

3. built-in high-breaking miniature circuit breakers, contactors, thermal relays, buttons and signal lights, etc., with overload, short circuit, leakage protection and other functions.

4. there is a special operating mechanism on the cover plate to realize full-close operation. padlocks can be installed according to requirements to avoid misoperation. the product can also operate normally under harsh conditions, ensuring the personal safety of the user.

5. the main switch and sub-switch operation panels are clearly distinguishable for easy on-site identification.

6. all exposed fasteners are made of stainless steel.

7. 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.

8. the inlet and outlet ports usually adopt pipe threads and are equipped with cable clamping and sealing devices. they can also be made into metric threads and npt threads according to the requirements of the user's site.

9. steel pipes and cable wiring are available.

10. the components and branches in the distribution box can be configured according to user requirements; the outdoor products can be equipped with rain cover according to user requirements.

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

main technical parameters


order note

1. accord with the model implication's rules to select regularly, and ex-mark should be added behind model implication;

2. if there are some special requirements, it should be pointed as ordering.
