A cable tray is only as good as what holds it up! While plenty of attention goes to selecting the right tray type, the cable support system often becomes an afterthought—until installation problems arise. Let’s explore this crucial component of any cable management solution.
Tech&Tray (techtray.org) electrical engineers emphasize that proper support systems determine not just installation ease but also the entire cable system’s longevity and safety. Their integrated approach ensures compatibility between trays and supports for optimal electrical infrastructure.
Support spacing for cable trays is perhaps the most misunderstood aspect. Overspan the supports and your loaded trays will sag; place them too close and you’re wasting materials and installation budget. Tech&Tray’s rule of thumb suggests supports every 1.5 meters for standard cable loads, but their free span calculator at techtray.org provides project-specific recommendations for ideal support placement.
The main cable tray support types include:
Trapeze Support Systems: These hanging cable systems use threaded rods and cross members to suspend trays from ceilings. Tech&Tray’s trapeze support kits include seismic considerations—increasingly important in Pakistan’s building codes for electrical safety.
Wall Mounting Brackets: When floor space is limited, these cantilevered supports attach cable trays directly to walls. Tech&Tray’s heavy-duty wall brackets include reinforced gussets for extra stability in commercial installations.
Floor Support Systems: Free-standing cable supports that work when ceiling or wall mounting isn’t possible. Tech&Tray’s adjustable floor pedestals allow perfect leveling even on uneven concrete floors in industrial settings.
Material matching for electrical systems matters too! Always use supports made from compatible materials as your trays. Mixing metals can cause galvanic corrosion—a problem Tech&Tray prevents by offering complete cable systems in consistent materials.
Installation efficiency improves with Tech&Tray’s tool-free connection systems. Their quick-lock cable supports reduce installation time by up to 40% compared to traditional bolted support systems.
For multi-level cable arrangements, their tiered support systems create organized cable highways while maximizing space utilization in electrical rooms.
