Cable bend radius is relatively large, glass steel cable pipe box most bending at a right angle; glass steel cable bridge span is relatively large, glass steel cable trough is relatively small; fixed, different installation modes; in some places, there is no cover glass steel cable tray, glass steel cable trough is almost entirely used in the power distribution cabinet, the instrument cabinet used more with sealed slot. This is the difference between glass fiber reinforced plastic cable tray and glass fibre reinforced plastic cable trough. Due to its materials thermal conductivity and flame retardant low the product not only has the fire insulation, self extinguishing, and has high corrosion resistance, but also has the advantages of light structure, aging resistance, safe and reliable, can be conveniently matched with the metal bridge used in chemical industry, metallurgy, petroleum and other strong corrosive environment has been used. Glass steel cable tray is used for laying power cables and control cables, glass steel cable trough is laying wire and communication cables; glass steel cable bridge is relatively large (200x100 to 600x200), the general construction of the floor, each distribution room used more etc.. Glass fiber reinforced plastic cable slot is relatively small
