你好，主要注意一下几点：1、扫管。传入钢丝后绑上棉布拖出，清扫管内的卫生。2、将要穿入的芯线捋直，不能有弯曲的地方，防止在线管内打结。3、线管内不能有污水等杂物，防止时间长了造成对芯线的绝缘层的损害从而导致漏电或短路事故。4、穿线时两边的施工人员，要配合好，一边在拖曳的时候，另一边要一起往线管里送，这样做起来会事半功倍。

1、一根穿线管中不要穿太多线，穿线后都应该拽一下，看看是否可以轻松拽动。2、电路走线应该把握“两端间最近距离走线”，不能无故绕线，这样不但会造成*线，还会增大电改投入。3、管径小于25的PVC穿线管拐弯应用弯管器，不能加弯头拐弯，直角*弯往往会造成*线。4、电路走线应该把握“两端间最近距离走线”，不能无故绕线，这样不但会造成*线，还会增大电改投入。5、最后最重要的是要使用穿线管埋线。

pvc穿线管安装需要注意的方法；1、管材表面硬度和抗拉强度优，管道安全系数高。 2、抗老化性好，正常使用寿命可达50年以上。 3、管道对无机*、碱、盐类耐腐蚀性能优良，适用于工业污水排放及输送。 4、管道摩阻系数小，水流顺畅，不易堵塞，养护工作量少。 5、材料氧指数高，属B2耐燃材料，具有自熄性。 6、管道线膨胀系数小，为0.07mm/m.0c,受温度影响变形量小。导热系数和弹性模量小，与铸铁排水管相比抗冰冻性能优良。 7、管材、管件连接可采用粘接，施工方法简单，*作方便，安装工效高。希望我的回答对你有所帮助
