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.

As we all know, an explosion-proof junction box is a connection device with explosion-proof and sealing properties for line laying. From the appearance, the explosion-proof junction box is a closed box. When the cable passes through, the cable enters and exits through the lock nut, which effectively avoids the sparking phenomenon in the connection. The shell is generally made of aluminum alloy. In order to make it have better fire resistance and corrosion resistance, aluminum alloy is usually sprayed on its surface.
