弱电工程中六类线缆在布线施工电缆压缩
Cable compression of six kinds of cables in wiring construction in weak current engineering
避免使电缆扎线带过紧而压缩电缆。在大的成捆电缆或电缆设施中最可能发生这个问题，其中成捆电缆外面的电缆会比内部的电缆承受更多的压力。压力过大会使电缆内部的绞线变形，影响其性能，一般会使回波损耗处于不合格状态。回波损耗的效应会积累起来，检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 比如：在挂在悬挂线上的长走线电缆中，每隔300mm就要使用一条电缆扎线带，如果挂在悬挂线上的电缆长40m，那么扎线次数为134次，其中的每个过紧的电缆扎线所引起的回波损耗都会积累起来，提高总损耗。因此在使用电缆扎线带时，要特别注意扎线带使用的压力大小。扎线带的强度只要能够支撑成捆电缆即可。
Avoid compressing the cable by making the cable tie too tight. This problem is most likely to occur in large bundled cables or cable facilities, where the cables outside the bundled cables will bear more pressure than the cables inside. Excessive pressure will deform the stranded wire inside the cable, affect its performance, and generally make the return loss in an unqualified state. The effect of return loss will accumulate. For example, in the long running cable hung on the suspension line, a cable tie shall be used every 300mm. If the cable hung on the suspension line is 40m long, the number of cable ties is 134, and the return loss caused by each too tight cable tie will accumulate to improve the total loss. Therefore, when using cable ties, pay special attention to the pressure used by the ties. The strength of the cable ties is sufficient as long as they can support bundles of cables.
