The main material of FRP cable tray straight is glass fiber reinforced plastic(FRP). FRP is a composite material made of glass fiber as a reinforcing material and a polymer resin matrix through a special process. The FRP material itself has good electrical insulation properties, which provides a safer laying environment for cables and effectively prevents electrical accidents caused by the conduction of the bridge. Especially in high-voltage or complex electrical systems, FRP cable tray straight can maximize electrical safety. The product also has flame retardant properties, with an oxygen index of ≥28, which means that its burning rate is low when it encounters fire, which can effectively suppress the spread of fire. This bridge straight is manufactured using a one-piece molding process, and the overall structure is strong and stable, ensuring the bridge's load-bearing capacity and long-term durability. The internal wall is smooth and burr-free, which effectively reduces the wear of the cable in the bridge, extends the life of the cable, and avoids damage to the cable insulation layer caused by rough surface.
