Petrochemical plants use explosion-proof power distribution box wiring and its layout

 Explosion-proof power distribution box is mainly used in the environment prone to explosion risk, and because of this, so the explosion-proof power distribution box wiring and layout is strictly stipulated, the following is a detailed description for you.

Explosion-proof power distribution box is applied in dangerous environment. The installation direction, laying method, material and connection way of the electric wires should meet the safety standard of explosion environment, which should meet the following requirements.

Bearing. Explosion-proof power distribution box of wire line configuration should be far away from the explosion source. Where there is a danger of explosion floors built a blast wall outside, at the same time, explosion-proof electrical wiring circuit configuration should decorate the outside of the blast walls. When the environmental risk of explosion gas, explosion-proof power distribution box of wire connection should be arranged in the position of the lower level.

2. Wiring method of explosion-proof power distribution box: in explosive dangerous environment, explosion-proof power distribution box mainly adopts explosion-proof steel tube to wrap the lines and cables. If the safety grade is not reached, then thick wall tube can be used to cover the lines and electricity of explosion-proof power distribution box to conduct pressure test.
