In our example (with the blue background), a span of 2.25 m for the cable tray produces a maxi-mum load capacity of 0.75 kN for each running metre of cable tray.

Cable Support Distances

This provides distances for cables based on their diameter and cable type. Prysmian was instrumental in providing this information and an extract is provided in this document.

TECHNICAL AND SIZING DATA

The optimum span, which varies according to the tray type, the type of support method and labour rates (field vs. shop) can be determined by doing estimates of cost installed for a few trial spans.
