Cablofil makes lighter work of installing lighting at T5

More than 400 lights are secured to the curved ceiling of T5B at Heathrow Airport by a supporting system based on Cablofil wire-mesh cable tray.
A bespoke lighting-support system for Terminal 5B at Heathrow Airport has been designed by Cablofil based on its wire-mesh cable tray. Working with Crown House Technologies, Cablofil devised a system that was simple to install and secures more than 400 lights to the curved ceiling of the terminal building, carrying power and digital control signals to each fitting. In just 18 months, the two companies designed, developed and fitted a system that incorporates customised yoke brackets to secure 3 m lengths of wire tray upside down along ducts in the roof. A custom-designed solid metal lid covers the tray and is coloured to match the decor. The tray supports the weight of the fittings. Power and data cables are easily accessible from below because the lid is fixed with recessed clips. This solution was developed as an alternative to a busbar system that was being considered. Crown House project engineer Julien Hipeau says that the wire-mesh tray was easier to install. A major benefit of using Cablofil tray for the lighting was that installers were already familiar with the product. 400 km of wire-mesh cable tray has been used in T5, about three-quarters of it in services modules made off site by Crown House and the rest fixed traditionally. Wholesaler Hagemeyer supplied the Cablofil tray for the project.
