玻璃钢材质的电缆桥架和普通的电缆桥架的区别是什么
What is the difference between the FRP cable bridge and the ordinary cable bridge?
区别在于：
The difference is:
1、因材质不同，桥架敷设时支撑点的间距不同，金属桥架支撑点的要大一些，同时单位桥架的载荷也高一些。
1, because of different materials, the distance between the support points is different when the bridge is laid, the supporting point of the metal bridge is larger, and the load of the unit bridge is also higher.
2、使用环境不同，在湿度很大（常年大于85%）或有腐蚀性气体环境或在沿海有盐雾的环境中使用玻璃钢材质的桥架，其使用寿命要长。
2. The use of a glass steel bridge with a large humidity (more than 85%) (more than 85%) or a corrosive gas environment or a salt fog in the coastal area is used for a long life.
3、在电磁干扰较强的环境中，金属桥架分段接地，阻断对电缆的干扰能力好。
3, in the environment with strong electromagnetic interference, the metal bridge segment is grounded, blocking the interference ability to the cable.
