Cable tray length is selected based on the load to be supported, the distance between the supports (also referred to as the span), and handling and installation constraints.
Under normal circumstances, the distance between the support arms of the cable tray should be about 1.5 m – 3 m, and should be verified according to specific conditions.
Cable Tray Support Span: The distance between supports is a critical calculation. The cable tray support span must be determined based on the manufacturer''s load capacity chart and the total anticipated
When planning the vertical spacing between floor-mounted cable trays, the minimum distance should be 150 millimeters. This clearance prevents potential obstruction and ensures the
Some applications may require the cable tray to support the weight of a single, dead object in addition to the cable loads. Specifications typically require this to be applied at the midpoint of the span between
The load capacity of the cable trays according to the support width can be read off in the diagram using load curves – here, shown as an example for a cable tray with the tray widths 100 to 600 mm.
It emphasizes the importance of thorough material inspection and proper installation techniques to ensure the reliability and longevity of the cable tray system. Key
The support span is the distance of cable tray between supports. Your cable tray length must always be longer than or equal to the support span you have selected.
