What is explosion-proof junction box?

Explosion-proof junction box is a special equipment used in various high-risk places. Compared with ordinary junction boxes, it is a junction box with explosion-proof function after various explosion-proof transformations. It is mainly composed of a junction box, which is composed of a box body, a box cover and a threading port. There are wiring terminal blocks inside the box. The four walls of the box are equipped with more than one threading port. Each threading port inside the box is provided There is a winding shaft, the winding shaft is connected by a screw thread through the bottom of the box, and the box cover is used in conjunction with the box body, and there is a sealing rubber gasket between. Play a fixed buffer function, and will not affect the cleanliness of the cabinet.

With competitive price and timely delivery, MAM sincerely hope to be your supplier and partner.

What is main purpose of explosion-proof junction box &#;

1. Hazardous places with explosive gas mixtures: Zone 1, Zone 2

2. Explosive gas mixture: &#;A, &#;B

3. Temperature group: T1-T6

4. Dangerous places with explosive dust mixture: Zone 10, Zone 11, Zone 22

5. Temperature group (dust): T11-T13

Note: In dangerous areas prone to explosions, explosion-proof junction boxes are used as crossing boxes and branching boxes. The wiring can be sealed to prevent damage to the circuit caused by the explosion of the external environment, and to avoid problems such as sparks inside the circuit, which may cause safety hazards to the external surrounding environment. And can be used indoors and outdoors

What is Structural features of explosion-proof junction box&#;

1. The shell material is aluminum alloy, and the surface is sprayed with plastic

2. When the diameter needs to be changed, it can be specially made

3. Steel pipe or cable wiring

4. Meet the requirements of GB- and IEC standards

The above is the description of the use of the explosion-proof junction box. Sparks caused by short circuits in the junction box often have a huge impact on the hazardous area on the site. The explosion-proof junction box can prevent these accidents from happening. The quality of the junction box is related to the environment and people. Therefore, we must pay attention to the quality and installation details of the explosion-proof junction box, and we must not be careless.

How to choose explosion-proof junction box?

1. From the explosion-proof level of the explosion-proof junction box. For example, if the selected explosion-proof junction box is used in high-risk gas environments such as hydrogen and acetylene, a higher-level explosion-proof junction box needs to be selected. At the same time, we need to pay attention to the explosion-proof level. Backward compatible, for example, Class IIC explosion-proof products can be used in Class IIB explosion-proof areas, while Class IIB explosion-proof products cannot be used in Class IIC explosion-proof areas.

2. From the material of the explosion-proof junction box. The material of the explosion-proof junction box is generally divided into two types, stainless steel and special carbon steel. If the environment is more corrosive, choose stainless steel as much as possible; if the environment is less corrosive or not corrosive, you can choose an explosion-proof junction box made of special carbon steel.

3. From the price of the explosion-proof junction box. The price is also an important consideration when we buy. Sometimes we will be affected by the budget and we need to choose an explosion-proof junction box with high quality and low price or even good value for money. The price is set around the quality of the product. For the sake of safety, we still try not to choose too cheap explosion-proof junction box.

4. From the quality of the explosion-proof junction box. As a special equipment used in high-risk locations, the quality of the explosion-proof junction box is the most important. The explosion-proof junction box we buy should be produced by a manufacturer with a production license, and choose the EX mark. After ensuring the basic explosion-proof problem of the explosion-proof junction box, we can also check the length, tolerance range and material of the explosion-proof surface The thickness, whether the spraying is uniform, whether the surface is scratched, etc.

5. From the manufacturers of explosion-proof junction boxes. Professional explosion-proof manufacturers can control all aspects of product design, procurement, production, and inspection to ensure reliable quality and satisfactory service.
