The Difference between the CT and ET range of Cable Trays

Sep 10, 2012 | | 0 Comments

As a part of the company's Cable Support range, EzyStrut offers multiple types of cable trays. Some of the more common trays are the CT Cable Tray, and the EzyTray (ET, ET3, and ET5) range of trays. What are the key differences between these products and why would you choose one or the other?

The CT range is a perforated bottom cable tray. The perforations allow for a lot of air flow around your cables. CT Tray is made from sheet steel, either pre-galvanised before fabrication, hot dip galvanised after fabrication, stainless steel, or from aluminium and has a 20mm side wall which is tapered to allow for multiple lengths to be easily slid together if you need to join them. The standard length of the tray is 2400mm (2.4m). The CT tray system is available in multiple widths from 75mm through to 600mm. Multiple fittings, such as bends or risers are also available for CT tray to suit all widths, and normally are made available in a 150mm radius. It is possible to install flat, peaked, or peaked and vented covers onto CT Tray.

Another option for cable trays is the EzyTray range: Trays such as the ET, ET3, and ET5 are examples of laddertray type cable trays because of the ladder rung type nature of their construction. These laddertrays offer greater loads per metre over larger spans, and side rail heights in 45mm, 47mm, and 85mm. The EzyTray system allows for cutting and manual creation of bends, crosses, tees, and internal/external risers by making specific cuts on the tray and attaching either the radius plate (for bends, tees, or crosses) or riser links (for risers) along the edge with splice bolts.

The ET system is normally available in Pre-Galvanised steel or hot dip galvanised after fabrication, however a popular MTO choice is to paint/powder coat the cable tray a specific colour, such as electrical orange.
