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. 分開敷設(shè):當(dāng)電源線、控制線較少時(shí)，可安裝在同一電纜橋上，但電源線、控制線應(yīng)在中間隔墻分開敷設(shè)。

　　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.橋?qū)?在選擇電纜橋?qū)挄r(shí)，應(yīng)留出一定的空間供將來(lái)使用。

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

　　4. 電纜固定:當(dāng)橋梁水平敷設(shè)時(shí)，橋梁框架間的連接應(yīng)盡量設(shè)置在跨度的1/4處。水平電纜每2米左右固定一次，垂直電纜每1.5米左右固定一次。

　　4. Cable fixation: when the bridge is laid horizontally, the connection between bridge frames shall be set at 1 / 4 of the span as far as possible. The horizontal cable is fixed once every 2 meters or so, and the vertical cable is fixed once every 1.5 meters or so.

　　5. 支撐間距:支撐間距應(yīng)小于或等于荷載曲線的允許荷載和支撐間距。

　　5. support spacing: the support spacing shall be less than or equal to the allowable load and support spacing of the load curve.
