Cable Tray Cover

In the majority of cases, covers are not used on cable trays for technical or safety reasons, but due to the “raceway complex,” a feeling by specifiers that cables must be totally enclosed in metal. Quality tray cables have a life of 30 to 40 years without covers when exposed to the elements.However, if you shield the cable, then you cut out external interference. For example, a layer of aluminium foil between the wires and the outside coating of the cable prevents electromagnetic and radio signals from reaching the inner wires. The foil reflects interference away.
