The long-span cable bridge is generally assembled by extruded FRP profiles, and is suitable for power cables, control cables, lighting cables and accessories. Compared with the iron bridge, it has the advantages of long service life (generally designed for 20 years), convenient installation and low cost (the specific gravity is only 1/4 of carbon steel, no fire is needed in construction, the length of a single bridge can reach 8 meters, or even longer), convenient cutting and no maintenance.
The long-span cable bridge is a kind of bridge with large support span compared with ordinary cable bridge, and because of its delicate structure design, it has the characteristics of large bearing capacity, so it is not only suitable for indoor and outdoor cable overhead laying in oil refining, chemical industry, textile, machinery, metallurgy, electric power, television, broadcasting and other industrial and mining enterprises, but also can be used as underground engineering. For example, cable trenches and cable tunnel brackets in metro, civil air defense projects.
Long-span cable bridge includes long-span cascades, pallets, troughs, heavy load ladders, right-angle tees, multi-section tees, right-angle tees, and corresponding types of connectors, cover plates and pillars. Large-span cable bridge is equipped with cover plate, which should be specified when ordering, or ordered according to the type of cover plate.
Surface treatment of long-span cable bridge can be divided into plastic spraying, galvanizing, or baking paint. In corrosive environment, the bridge treated by plastic spraying can be selected, and in general atmospheric corrosion protection environment, the bridge treated by galvanizing can be selected.
1. It can avoid the problem of heating and high induction voltage caused by electromagnetic induction of metal guardrail under high electromagnetic field. It will not damage substation equipment and avoid electric shock to operation and maintenance personnel.
2. Weather resistance is good, no oxidative rust, no fading, no paint protection, no daily care, no fear of lightning strike in hot and humid state.
3. Corrosion resistance, in 10% sulfuric acid, 20% nitric acid, 50% acetic acid long-term effect is not affected.
4. The impact resistance is easy to recover, the elasticity after the impact is large, and the original shape can be restored. The tensile and bending strength is more than 600 pa, and the fatigue resistance is about 50 times of that of steel.
