The shell of the explosion-proof motor junction box is usually made of stainless steel or special alloy materials, which has corrosion resistance. Ordinary junction boxes are usually made of ordinary steel materials, which are easily corroded by chemicals in the environment and cause equipment damage. Explosion-proof motors are motors designed specifically for use in flammable and explosive places, and their electrical and mechanical properties must meet specific standards and specifications.

The explosion-proof motor junction box has a special explosion-proof structure, which can protect the safety of equipment and personnel even in dangerous environments such as explosions and fires. In contrast, ordinary junction boxes lack corresponding explosion-proof measures and are very likely to generate sparks in dangerous environments, causing explosions and other dangers.

The explosion-proof motor junction box is usually designed with the safe operation of the equipment in a humid or water-containing environment in mind, so it has good waterproof performance. Ordinary junction boxes usually lack this design and cannot guarantee the safe operation of the equipment under water immersion.

1. Protection level: The junction box of the explosion-proof motor should meet specific protection level requirements to ensure that it will not cause sparks and explosions in dangerous environments.

2. Wiring method: The wiring of explosion-proof motors must comply with specific standards and specifications. Usually, the "e" type wiring method is adopted, that is, the upper end wiring, so that the sparks generated inside the motor will not cause an explosion.

3. The material and grade of the terminal: The terminal of the explosion-proof motor usually uses materials that are not easy to conduct electricity, such as copper-aluminum alloy, etc., to achieve the effect of not generating arcs. The explosion-proof junction box is very different from the ordinary one, with high strength; the assembly mating surface finish requirements are relatively high, and there are strict dimensional requirements for the width of the joint surface. All the separations inside and outside the leads have strict sealing dimensional requirements.
