If the user can provide electrical schematics or electrical components, it is the best and most convenient. But if none of these are available, the following data can be provided to customize the explosion-proof power box.
1.The number of switches, the question of whether the main switch is necessary or not, and the current.
2.The number of branches and the branch current.
3.The direction of the inlet, whether it is the upper or lower inlet, the number of inlets, the thread specifications of the inlet, the direction of the outlet, the number of outlets, and the thread specifications.
4.Whether it is preservative or not, the anti-corrosion grade.
5.It is the installation method of the explosion-proof power box, whether it is vertical or hanging, if it is hanging, if there are no special requirements, you can choose cast aluminum explosion-proof power box, if it is vertical, it is best to be a steel plate or stainless steel welded explosion-proof shell.
What is the difference between explosion-proof powerbox and powerbox?
Explosion-proof power box is a kind of power box with explosion-proof performance. There are mainly explosion-proof lighting distribution boxes, explosion-proof power distribution boxes, explosion-proof and anti-corrosion distribution boxes, etc. It is mainly suitable for lighting in flammable and explosive places such as petrochemical plants, oil platforms, gas stations, oil pump rooms, and transfer stations. For use in Zone 1 or Zone 2** gas atmospheres. Zone 21 and Zone 22 combustible dust environment.
The power box is a circuit distribution box for all users. The power box is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or screen width according to the requirements of electrical wiring to form a low-voltage power distribution device. During normal operation, the circuit can be switched on or off with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit is cut off or alarmed with the help of protective appliances. The measuring instrument can be used to display various parameters in operation, and some electrical parameters can also be adjusted, and deviations from the normal working state can be prompted or signaled. It is often used in various power generation, distribution and substations.
