Explosion-proof junction box is an electrical equipment used in hazardous environments, mainly used to connect and distribute wires to protect the safe operation of electrical systems.

Ø Applicable Environment  

Explosion-proof junction boxes are suitable for zones 1 and 2 in hazardous areas with explosive gas mixtures and zones 20, 21 and 22 in hazardous areas with explosive dust mixtures. It can be used indoors and outdoors, and can withstand the effects of different levels of explosive gas mixtures (IIA, IIB, IIC) and explosive dust.

Ø Structural Characteristics  

1. Shell material:

- Usually cast aluminum alloy shell or steel plate welded molding, with high strength and corrosion resistance.

- The surface can be painted or sprayed to enhance its anti-corrosion and explosion-proof properties.

- It can also be made of stainless steel on demand to adapt to special environments.

2. Sealing performance:

- With good sealing performance, prevent explosive gas, dust and water into the box.

- Use rubber sealing ring, sealant and other sealing materials to ensure the tightness of the box.

3. Wiring method:

- Provides a variety of wiring methods, such as terminal block wiring, cable connector wiring, etc., to facilitate users to make electrical connections.

- Terminals should have good electrical conductivity and fastness to ensure the reliability of electrical connections.

4. Installation method:

- Can adopt hanging, floor type and other installation methods to adapt to different installation environments.

- The mounting bracket should be firm and reliable to ensure the stability of the junction box.

Ø Product Features  

1. Explosion-proof performance:

- Designed and manufactured in strict accordance with national explosion-proof standards, with reliable explosion-proof performance.

- Can prevent electrical sparks, electric arcs, etc. from causing explosion accidents in dangerous environments.

2. Protection level:

- Usually has a high level of protection, such as IP65, IP66, etc., which can effectively prevent dust, water and other foreign objects from entering the box.

- Protect electrical equipment from the external environment and improve its reliability and service life.

3. Flexible configuration:

- Can be customized according to the needs of users, configure different numbers and types of terminals, switches, indicators and other electrical components.

- Meet the connection and control requirements of different electrical systems.

4. Easy maintenance:

- Reasonable design, easy to install and maintain.

- The door is easy to open, which is convenient for the repair and maintenance of electrical equipment.

Ø Precautions for Use  

1. Check the appearance and internal structure of the junction box before installation to ensure that there is no damage or deformation.

2. The installation should be carried out in accordance with the requirements of the manual to ensure that the installation is firm and reliable.

3. Wiring should be strictly in accordance with the electrical schematic to ensure that the wiring is correct.

4. The sealing performance and explosion-proof performance of the junction box should be checked regularly during use, and problems should be dealt with in time.

5. Do not open the junction box door in a dangerous environment to avoid explosion accidents.
