What is the difference between explosion proof wire box and explosion proof junction box?

As we all know, explosion-proof wire box and explosion-proof junction box are stainless steel welding or aluminum alloy casting made, and all have explosion-proof role, and the same level of protection, mainly used in chemical factories, storage and transportation, pharmaceutical industry, national defense, crude oil and other flammable and explosive places. But explosion-proof junction box and explosion-proof junction box, although only a word difference, but the structure of the composition, application scenarios, as well as the type of explosion-proof are different, the following is to tell you the difference between the two.

Explosion-proof wire box role?

Explosion-proof wire box role is when the distribution line is installed too long, the whole pipe is not beneficial to the installation of the line, the distribution line is too much turn, the distribution line divergence with the distribution line to assist in connecting the efficacy of the line. Explosion-proof threading box is mainly used for steel pipe wiring, as galvanized pipe connection, bending and branching. It is not allowed to make joints in the explosion-proof junction box.

Explosion-proof junction box role?

Explosion-proof junction box is used for cable and equipment, cable and cable connectors, generally used in explosion-proof areas of the lighting threading connection, circuit branching, fixed lamps and lanterns. Explosion-proof junction box is a kind of circuit laying for explosion-proof and strong sealing connections. From the appearance of a closed box.

1. Composition gap between the two structures

Explosion-proof wire box structure is relatively simple, generally by the box, box cover, sealing gasket and other components, explosion-proof wire box is empty inside. Explosion-proof junction box structure is relatively complex, there are terminals for wiring.

2. The scope of application of the two are different

Explosion-proof junction box scope of application.

1.1 zone, zone 2 explosive gas environment.

2.20 zone, 21 zone, 22 zone combustible dust environment.

3. Applicable to IIA, IIB, IIC class explosive environment.

4. Suitable for temperature group T1-T6 environment.

Explosion-proof junction box is a variety of high-risk places to use special equipment, and civilian junction box than, it is after a variety of explosion-proof transformation into a junction box with explosion-proof function. It is made of aluminum alloy die-casting or stainless steel welding.

Explosion-proof junction box scope of application:

Applicable to explosive gas environment zone 1, zone 2;

Suitable for ⅡA, ⅡB, ⅡC class explosive gas environment;

Suitable for combustible dust environment 20, 21, 22 area

Suitable for environments with temperature group T1-T6;

For petroleum refining, storage, chemical, pharmaceutical, explosive environment and hazardous chemical warehouse facilities and other explosive hazardous environments.

3. Difference of explosion-proof type

Explosion-proof wire box explosion-proof type is usually Exe increased safety, and explosion-proof junction box explosion-proof type for the Exd explosion-proof type, according to the different gas groups, commonly used in factories have IIC-class explosion-proof junction box and IIB-class explosion-proof junction box two. Explosion-proof junction box must be reliably grounded when in use.

1, the installation work must be completed by professionals.

2, before the construction of the factory nameplate to check the explosion-proof junction box listed in the basic standard value is not in line with the actual use of the norms.

3, check the explosion-proof junction box fastening seals and sealing rings are complete and effective.

4, explosion-proof junction box and site grounding protection to be connected to each other, the grounding system should be firm and reliable.

5, all the standard parts are fixed immobile countermeasures, not easy to fall down independently.
