使用中的长途通信电缆,有些地段由于电缆损坏严重或被压在地面建筑物下等原因,必须敷设一段新电缆进行割接,替换被废弃的局部电缆,以保证长途通信电缆的全程特性和安全可靠。我段在施工中总结出一套不影响电缆正常使用,安全顺利完成割接任务的行之有效的方法,现在介绍如下: 1、对既有电缆进行调查,确定部分电缆必须更换的原因、长度及对干线电缆的影响,掌握被废弃部分电缆的原有加感、交叉、分歧、气压传感器及地线等资料。并确定新设电缆的径路、长度以及中间是否需要加感、安装气压传感器及地线等。割接点要尽可能选在原有电缆接头,以便割
In use, the long-distance communication cable, in some areas due to serious damage to the cable or being pressed on the ground under the building and other reasons, must be laying a new cable cutover, replacement of abandoned local cables to ensure the full characteristics of long-distance communications cables and security reliable. I have summed up in the construction of a set of does not affect the normal use of the cable, the successful completion of cutover task safe and effective method, are described below: 1, the existing cable to investigate to determine the reasons for the cable must be replaced part of the length And the impact on the trunk cable to master the abandoned part of the original cable sense, cross, divergence, pressure sensors and ground and other information. And determine the new cable path, the length of the middle and whether the need to add flu, installation of pressure sensors and ground and so on. Cutting joint to be as possible in the original cable connector, in order to cut
