How much spare capacity is planned?
A reserve for future cables is agreed with the client at design stage and recorded in the tray fill calculation, so circuits can be added without replacing the route.
Products we supply
Cable Trays & Cable Management
Galvanised cable trays, ladders and accessories, sized for cable weight, fill and support spacing.
01Overview
Supply and engineering from one team
Powersense supplies cable tray systems with bends, junctions, supports and fixings, and engineers the routes: load class, width and support spacing, segregation of power and data, and coordination with other services.

02Scope and process
Engineering scope and deliverables
- 01
Cable inventory and fill
Cable types, diameters and weights are listed for each route, and spare capacity for future cables is planned.
DeliverableCable inventory - 02
Tray width and load class
Width and load class are selected from the total weight per metre and the safe working load of the system (IEC 61537).
DeliverableLoad and width calculation - 03
Support spacing and fixings
Support spacing and bracket loads are checked for deflection and for the capacity of the building structure.
DeliverableSupport layout - 04
Segregation and EMC
Power, control and data routes are separated or screened to limit interference (IEC 60364-5-52, EN 50174-2).
DeliverableSegregation matrix - 05
Corrosion protection
The finish is chosen for the environment: hot-dip galvanising (EN ISO 1461) for industrial and commercial interiors, other materials on request.
DeliverableMaterial specification - 06
Installation and earthing
Expansion joints and the bonding continuity of metallic trays are checked at installation (IEC 60364-5-54).

06Technical notes
Technical notes and FAQ
Why are power and data cables separated?
Parallel runs couple interference into signal cables. Segregation distances or screened trays, as described in EN 50174-2, reduce it.
