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.

大跨距电缆桥架共包括大跨距的梯级、托盘、槽式、重载荷梯架、直角三通、多节三通、直角四通，以及相应型号的连接件，盖板和支柱。

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.

大跨距电缆桥架表面处理分塑料喷塑、镀锌，或烤漆等处理。在腐蚀性环境中，可选用经过塑料喷涂处理的桥架，在一般大气防腐环境中可选用镀锌处理的桥架。

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.可以避免金属护栏在高电磁场下的电磁感应带来的发热、高感应电压问题，不会对变电设备产生损坏，避免运行维护人员遭受电击。

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.耐候性好，在湿热状态下不发生氧化锈蚀，不褪色，不需刷油漆保护，不用日常护理，不怕雷击。

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.耐腐蚀，在10%的硫酸、20%的硝酸、、50%的醋酸长期作用下不受影响。

3. corrosion resistance is not affected by the long-term effect of 10% sulfuric acid, 20% nitric acid, and 50% acetic acid.

4.电缆桥架耐撞击易复原，受到物体撞击后弹性大，能恢复到原形状，拉伸、弯曲强度为600pa以上，抗疲劳能力约为钢材的50倍。

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.
