A large span cable bridge is equipped with a cover plate, which needs to be explained at the time of order, or to be ordered by the type of cover plate.
The long span cable bridge consists of large-span cascade, pallet, trough type, heavy-duty ladder rack, right angle three way, multi section three way, right angle four way, and the corresponding type connection piece, cover plate and pillar.
The surface treatment of large span cable bridge is treated by plastic spray, galvanizing, or baking varnish. In corrosive environment, a bridge with plastic spraying can be selected and the galvanized bridge can be used in the general atmosphere anticorrosion environment.
1., it can avoid the problem of heating and high induction voltage caused by electromagnetic induction in metal guardrail under high electromagnetic field. It will not damage the substation equipment and avoid running and maintenance personnel suffering from electric shock.
2. good weather resistance, in the hot and humid state of no oxidation corrosion, color fading, no paint protection, no daily care, not afraid of lightning.
3. corrosion resistance is not affected by the long-term effect of 10% sulfuric acid, 20% nitric acid, and 50% acetic acid.
4., the cable bridge is easy to recover from impact and is resilient after impact. It can restore to the original shape. Its tensile and bending strength is above 600Pa, and its fatigue resistance is about 50 times that of steel.
