1. When the bridge height is 50 and 100, there are 6 connection holes at both ends; when the bridge height is 150 and 200, there are 12 connection holes at both ends.

　　2. 分开敷设:当电源线、控制线较少时，可安装在同一电缆桥上，但电源线、控制线应在中间隔墙分开敷设。

　　2. Separate laying: when the power line and control line are less, they can be installed on the same cable bridge, but the power line and control line should be laid separately in the middle partition wall.

　　3.桥宽:在选择电缆桥宽时，应留出一定的空间供将来使用。

　　3. Bridge width: when selecting cable bridge width, certain space shall be reserved for future use.

　　4. 电缆固定:当桥梁水平敷设时，桥梁框架间的连接应尽量设置在跨度的1/4处。水平电缆每2米左右固定一次，垂直电缆每1.5米左右固定一次。
