The cable plate level, the connecting head between the bridges is as long as possible about 1/4, and the horizontal cable fixed interval is about 2 meters, the vertical cable is fixed once, and the cable plate should be the feasible ground construction demand every 1.5 meters.
整个桥应该有良好的电渗透,联合桥的一部分,连接电阻不大于0.00033哦,长距离的电缆盘应该温度补偿措施(一般钢桥每30米,铝合金桥每15米),电缆盘每30 ~ 50米地再次。
The entire bridge should have good electrical permeability, part of the joint bridge, the connection resistance is not more than 0.00033 Oh, the long distance cable plate should be temperature compensation measures (general steel bridge every 30 meters, aluminum alloy bridge every 15 meters), cable disk every 30 ~ 50 meters again.
Before the installation of the cable bridge, the load, the size of the bridge, the deflection and the proper span should be calculated according to the structural features of the building, and the deflection of the required loads and the convenience of installation should also be considered.
Outdoor piping can also be considered, but it should be noted that the cable tray should be installed along the flammable, explosive and low-risk side. When explosive gas is lighter than air, the bridge should be installed underneath, and vice versa. The bridge should avoid parallel laying at or below the pipe.
