31、 the steel pipe (wire pipe), firstly check whether shields at every pipe orifice are in good order. If there is some leakage or damage, all of them should be supplemented and replaced. 2）当管路较长或转弯较多时，要在穿线的同时往管内吹入适量的滑石粉。If the pipeline is longer or there are more swerves, inbreathe some suitable talc

32、in the pipe while threading. 3）两人穿线时，应配合协调，一拉一送。When threading, both personnel should coordinate harmoniously, one pulls and the other releases. （7）导线连接 Wire Connection：1）单芯线并接头：导线并齐合拢。在距约12mm处用其中一根线芯在连接端缠绕5-7圈后剪断，把余头并齐折回压在缠绕线上进行涮锡处理。 Single core with parallel joint: conducting wires are combined an

33、d gathered up. At 12mm to it, use a wire core winding 57 circles at the joint and then cut off. Combine the rest and fold them at the wind wire to carry out the treatment of rinsing tin. 2）不同直径导线接头：如果是独根(导线截面小于2.5mm2)或多芯软线时，则应先进行涮锡处理。再将细线在粗线上距离绝缘层15mm处交叉，并将线端部向粗导线(独根)端缠绕5-7圈，将粗导线端折回压在细线上，最后再做涮锡处理。Wi
