FRP槽型 cable trays are a fully enclosed cable tray suitable for laying computer cables, communication cables, thermocouple cables, and other sensitive system control cables. They provide excellent protection against shielding interference and heavy corrosion environments for cables. FRP槽型 cable trays are lightweight, with a high bearing capacity, weighing only 1/4 of the cable's weight and 1/10 of the weight of a cement cable trough. They have a service life of 30-50 years.
