40、作命令，全线听从指挥，应同时用力或停止，遇转弯或穿管时，应先将电缆甩出一个大弯，再往前拉；电缆敷设时，电缆应从电缆盘的上方引出，引出端头如有松弛，应用绑线绑紧，电缆盘的转动速度与牵引速度应很好的配合，每次牵引的电缆长度不宜过长，以免在地上拖拉。敷设过程中，如发现电缆局部有压扁或折曲伤痕严重的，应停下来检查鉴定，严重者应割去。新敷设的控制电缆不允许有接头。电缆应有足够的备用长度，以补偿因温度变化而引起的变形，电缆跨越建筑物伸缩处应留有余度，以适应变化。每根电缆敷设好以后，必须待两端留有足够长度，各转弯处再作初步固定，直线段初步整理过并已符合设计要求时，才允许锯切。每根电缆敷设完后，应及时挂上标志
41、，在敷设下一根电缆。因工程进度需要或供应的关系，一个断面内排列的电缆不能一次敷设完毕时，把不能及时敷设的电缆位置留出来。电缆敷设告一段落后，应进行全线的整理。Commander:Commanderswhistleisactionorder,arrangesectioncommandersatturningorlongroute,takeleading-outendasmainmainactionorder,allthepersonstakeorders,allthepersonsshouldforceorstopatthesametime,ifthereisaturningorcablelea
