Glass fiber reinforced plastic trough cable tray is a fully enclosed cable tray suitable for laying computer cables, communication cables, thermocouple cables, and other sensitive system control cables. It offers excellent protection against shielding interference and heavy corrosion environments for cables. The glass fiber reinforced plastic trough cable tray is lightweight with high load-bearing capacity, weighing only 1/4 of the cable itself and 1/10 of the weight of a cement cable trough. It is designed for a service life of 30-50 years.
