Should cables routed in cable trays be flame-retardant

Surfaces should be coated with fire-retardant paint to slow flame spread and increase heat resistance. Install fire barriers within the tray to isolate different fire zones. When cable trays pass through walls or floors, seal openings using fire-rated penetration sealing materials. The most common flame test is UL 1685 Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables. This test involves loading multiple cables in a vertical section of cable tray and igniting the cable. One of the most widely referenced international standards for flame retardant cables is IEC 60332, which evaluates how cables behave when exposed to flame conditions. Understanding IEC 60332 testing helps engineers, contractors, and project managers choose the right cable solutions to limit flame. Electrical lines can ignite themselves due to overheating or a short-circuit or they can be set alight by the external influence of fire or heat. Our tested solutions for cable fire protection. Although the type of cable and conductor is the determining factor in the fire behaviour of ducts and conduits, the choice of cable tray type and the installation of the latter in line with installation precautions are just as crucial.
