The explosion-proof junction box of explosion-proof junction box is a sealed box, which is generally made of cast metal to meet the explosion-proof requirements. The cable of the explosion-proof junction box is connected to the explosion-proof lock, and the explosion-proof lock is fixed on the cylinder to prevent the connector from generating sparks, so as to achieve the purpose of safe wiring.

When working in an explosive gas environment, the circuit in the explosion-proof junction box produces sparks, or harmful gas penetrates into the junction box, and there is a small range of deflagration under the spark. These dangerous accidents can happen.  Therefore, when the pure epoxy powder is sprayed on its surface, the junction box will not be exposed to the fire environment due to unrestrained or broken, causing the environment to explode.
The explosion-proof junction box is generally a die-cast aluminum alloy shell, which is a connection protector with sealing performance advantages in the layout of explosion-proof electrical circuits. The internal use of the terminal is for the connection of various cables, and the housing has sealing technology to seal the cable connection. Therefore, it can be used for control, lighting, as well as for power lines and cables, and as an air supply circuit.
Through the above introduction and analysis of the role and characteristics of explosion-proof junction boxes, hope it helps you.
