Direct Manufacturer All sizes above are measured from the outer edge of the services. Cables can be bundled together into a maximum 100mm diameter bundle and each bundle should be spaced 100mm apart from each outer
Direct Manufacturer A clear horizontal air gap of ≥ 300 mm shall be maintained between tray edges along all parallel runs on the roof. Where the gap cannot be preserved
Direct Manufacturer Note 3: This regulation precludes, for example, the use of non-metallic cable clips or cable ties as the sole means of support where cables are clipped direct to exposed surfaces or suspended under
Direct Manufacturer Cable trays in high-rise buildings need to be carefully designed to withstand high temperatures and prevent the spread of fire between floors.
Direct Manufacturer For example, a cable tray may contain electrical cables powering essential services that are still required to operate under extreme fire conditions.
Direct Manufacturer Cable Support Distances Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. Section 522.8 (Other Mechanical Stresses (AJ))
Direct Manufacturer This guide covers cable ladder systems, cable tray systems, channel support systems and associated supports intended for the support and accommodation of cables and possibly other electrical
Direct Manufacturer Reduction of the support spacing: The smaller the support spacings are between the suspension points of the cable trays, the less the sagging will be if there is a fire.
