-Explosion-proof lighting fixtures can be directly suspended through steel pipe wiring using junction boxes with lifting covers.

Explosion-proof junction boxes are used in hazardous areas, primarily within buildings and structural frameworks, as well as for cable direction changes. Cable conduit connections are made with explosion-proof junction boxes, while conduit-to-ground connections use flexible hoses. Metal hoses or flexible connections are applied as protective tubing when the explosion-proof junction box is connected to the local surface of thermocouples, resistance thermometers, transmitters, etc. Elbows are commonly used at bends in explosion-proof junction boxes. An explosion-proof junction box should be installed when there are more than two 90° elbows or the straight conduit length exceeds 30m.
