摘要
目前电缆的选型越来越大,大型号电缆在管道内敷设时,由于负荷拉力较大,加上牵引绳和电缆长时间与电缆管道、电缆井基础摩擦,给电缆的敷设带来极大的阻力,轻者损坏电缆井和电缆管道,重者损伤电缆,严重地影响了电缆的使用寿命。
The growing selection of cables, cabling when large models in the pipeline, due to the large load of tension, combined with a long leash and cable raceways, cable wells foundation friction, to bring the cable laying great resistance, light wells and damage the cable raceways, severe damage to the cable, which seriously affected the life of the cable.
