Large span steel cable trays

The most prominent feature of the large span cable tray is that the length of the unit number of bridges is very large, the largest can reach several meters. General use of the life is relatively long, and low installation costs, installation is very convenient, often used for long-distance power transmission cable erection, its superiority is very obvious.

It is mainly divided into metal and glass fiber reinforced plastic profiles of two materials, glass fiber reinforced plastic material is generally assembled from pultruded glass fiber reinforced plastic profiles, suitable for power cables, control cables, lighting cables and accessories. Compared with the iron bridge, has a long service life (general design life of twenty years), easy to install and low cost (specific gravity is only 1/4 of carbon steel, construction without fire, a single bridge length of up to 8 meters, or even longer), easy to cut, do not need to be maintained and other superiority.
