Home / Spacing of cable tray anti-sway supports
Short Span trays, often used for non-industrial indoor installations, are typically supported every 6 to 8-feet, while Intermediate Span trays are typically supported every 10 to 12-feet. The safety of your people and the reliability of your electrical system depend on proper cable tray support spacing. When developing our cable support OBO can offer reliable solutions for systems, three attributes are at the routing and fastening cables securely core of what we do: efficiency, resil- for each of these installation challeng-ience and safety. Cable trays play a vital role in supporting electrical cables and wires in commercial, industrial, and utility installations.

Discover the essential cable tray spacing requirements for safe and efficient installation. Learn key standards, horizontal and vertical spacing, and more.
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))
For three‐phase, single conductor cables, these forces cause violent thrashing of the individual conductors, frequently resulting in inadequately supported cables jumping out of their cable tray or
Each run of conduit or cable tray must have at least one transverse supports at each end of the run and at least one longitudinal support anywhere on the run. Pre-approved manufacturer''s/industry
Seismic braces can be flexible using aircraft quality cables, or rigid (solid) using steel sections such as pipe, angles, or strut channels. Braces are typi-cally installed 30-40 ft (10-13 m) apart, at system
