Selection of cable trays for explosion-proof workshops
Thread Content
For explosion-proof workshops, what type of cable tray should be used? Regular slot type? /Fire protection?
How is it that no one knows? In a hurry?
Generally, flame-retardant ordinary cable trays can be used for installation; ZR flame-retardant cables should be employed, and no joints are allowed within the tray.
Thank you for the reply from the third floor! But it’s not clear yet. May I use a regular galvanized steel cable tray? Can I choose a regular cable as well?
Galvanized steel cable trays are fine. Ensure proper connections at the joints of the cable trays, and ensure that the trays are properly grounded. It is advisable to use flame-retardant armored cables
I would also like to ask everyone: can ladder-type cable trays be used for laying power cable circuits in explosion-proof areas? (The cable is flame-retardant.)
Metal can be used for the cable trays; as for the selection and installation of cables, it is necessary to comply with the electrical design and construction standards for explosive hazard areas.
