In explosion-proof areas, is it necessary to add explosion-proof connectors at the network cable interfaces?
Thread Content
In an explosion-proof area, my control cabinet requires an external network cable that is connected and disconnected frequently. Is it necessary to use an explosion-proof plug at the connection point between the network cable and the control cabinet? I found in my research that the voltage inside an Ethernet cable is around 3V. Does that mean I don’t need an explosion-proof plug, but only a simple waterproof connector will suffice? Please ask an expert to help answer it
In explosion-proof areas, explosion-proof network cables are generally used, and explosion-proof plug connectors need to be added as an accessory
Explosion-proof aviation plugs are necessary.
Is it because 3V electricity can generate electric sparks on site, leading to safety accidents? Or are there corresponding regulatory requirements that mandate doing this?
The voltage in the instrument 485 communication cable is also only around 5 volts. In explosion-proof environments, they must also be sealed with explosion-proof flanges. There are regulations for this
I think it’s necessary to add explosion-proof measures. You can consider two aspects: first, the control cabinet should not be connected to the external explosion-proof area through network cable connectors, as there are other electrical components inside the cabinet that also need to be separated from such connections. From a practical standpoint, if someone conducts a safety inspection and you explain that it’s just a network cable, they might not believe you; after all, it’s just called a network cable. So, it’s always better to take an extra step.
Mm, learned it: handshake
