The difference between explosion-proof distribution box and ordinary distribution box is:
In terms of shape, the ordinary distribution box is made of iron, and the explosion-proof distribution box is made by casting or welding of steel plates and has high strength.
In terms of structure, components in an ordinary distribution box can be arranged together with convenient wiring. The explosion-proof distribution box is divided into several units and each switch and electrical component must be isolated.
In terms of sealing, the ordinary distribution box does not require strict sealing. The explosion-proof distribution box lid and the box body are sealed well. After passing the strict inspection, the special agency will issue a certificate of conformity and sell it to the factory.
In application, ordinary distribution boxes are generally used in civilian and places without explosion-proof requirements. Explosion-proof distribution box is mainly used for dangerous combustible gas places and explosive places.
On the price, ordinary distribution boxes are cheap. Explosion-proof distribution boxes are expensive, which is generally several times the price of ordinary distribution boxes.
