In designing supports for a cable tray system, consideration should be given to the loads associated with future cable additions and any additional loading that may be applied to the cable tray system (e.g.,
The above issues can be minimized to a great extent if we can install the instrumentation cable trays in vertical orientation .Although a little bit higher
Before beginning installation, be sure that the method statement for installation of cable tray, trunking, and accessories is approved by the project and construction manager before the
Cable or "P" clamps and plastic tie wraps are used to fasten cables/conductors to the ladder tray. Single conductors must be fastened to prevent excessive movement generated by fault current magnetic
Cables may be fastened to the cable tray by means of cable clamps or cable ties (See Figures 5.7 and 5.8). Generally, cables are fastened every 450 mm (18 in.) on vertical runs.
As demonstrated in the previous paragraph, Optical Cable Corporation''s cable can be installed in vertical rises for great distances. However, due to the practical nature of installing cable, the weight
