Larger spans reduce support count but increase required tray strength. IEC 61537 classifies trays by safe working load at a given span. Here are a few things to consider when installing a. After cable laying, the deflection of the cable tray should not exceed 1/200 of the span of the cable tray. These systems, made from metal or plastic, are open structures designed to support electrical conductors, ensuring proper organization and safety. IS 12352 and IEC 61537 define classification and test. This involves choosing between different types, such as ladder or ventilated trough, understanding support spans, and implementing correct conductor management to prevent issues like overheating and physical damage.
