How to see the explosion-proof distribution box drawings
This is a complete explosion-proof distribution box drawing, which consists of 7 sub-switches and 1 main switch. At the beginning, the customer sent the wiring diagram, which was quoted by our Senn explosion-proof engineers at the right price. The engineer then designed the outline drawing, such as the one above, which has a frame size of 900*600*170 and consists of six small casings. The upper part is composed of an explosion-proof cavity, and the lower part is composed of an increased safety cavity. The difference is a switchgear and one for wiring. At the bottom is the wiring in and out of the hole, this is generally confirmed by the user, the size of the hole should correspond to the steel pipe or explosion-proof hose.
The explosion-proof distribution box has an explosion-proof rating of ExdeIIBT4, and a higher grade is ExdeIICT4. When ordering the explosion-proof box, the manufacturer must make a request: the protection grade IP54 belongs to the indoor installation. If the outdoor installation grade is IP65, there are also the entry and exit line mode, the component brand model, the use environment, the installation method and so on. Can be seen from the drawings. Therefore, the engineer must draw a drawing for the customer to confirm before production.
