Explosion-proof wire glands and waterproof wire glands
Thread Content
Dear marine friends, when laying cable through pipes in explosion-proof areas, do you use explosion-proof wire glands or waterproof wire glands?
Based on your description, in this case the explosion-proof performance of the junction box should be considered first.
Can explosion-proof wire glands be omitted in explosion-proof areas?
Explosion-proof junction boxes must be used in explosion-proof areas

Is it still necessary for the wire conduit to be explosion-proof once it’s placed in the cable tray? I haven’t heard of any explosion-proof cable trays being available. What’s important is to choose explosion-proof gland fittings for the instrument side and the junction box side. Let’s take a look at the requirements in the installation specifications first.
I think what this guy says makes sense; it’s just for threading wires, there’s no need for explosion protection
Those who are willing to look up information can refer to the 2010 edition of the control system installation manual. It’s likely that someone mistook the wire conduit box for a junction box, which is why there are so many problems.
It depends on your requirements for protection level, explosion-proof rating, and corrosion resistance! Under normal circumstances, explosion-proof wire glands are used, as they can achieve an IP55 rating.
We all use galvanized connectors directly. Galvanized pipes themselves may not meet explosion-proof requirements, and the threaded connections of explosion-proof wire glands cannot either be made to meet explosion-proof standards. It’s just convenient to pass wires through the wire box when the distance is relatively large. Easy piping installation
