Cable tray climbing temperature requirements

Home / Cable tray climbing temperature requirements

While fiberglass cable tray systems utilize a heat-cured resin that doesn't melt at higher temperatures, it's important to realize there is a slight loss of rigidity at continuously elevated temperatures. In 1993 NEC Article 318 there are no requirements for the handling of the thermal contraction and expansion of cable tray. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned in this technical guide only apply to our own cable management ranges and cannot under any circumstances be transposed to si osure, overheating or. Mechanical Strength The cable tray must withstand the load of cables, environmental factors, and external pressure. Locating cable tray over a boiler or in close proximity to a large furnace can produce some rather high temperatures.
