安装pvc管穿线管最重要的是要使用穿线管埋线。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、线路有接头必需在接头处留暗盒扣面板，日后更换和维修都方便。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，直角死弯往往会造成死线。

布线材料一般由电线、PVC线管及线面配件以及电气开关等组成。由于每一种材料都有很多品种，质量好坏不一，因此价格相差很大。就电线来，一般常用电线规格为25、4、6、10，平方毫米等，而每一种规格又有很多品种，如BVT(双塑保护)、BV(单塑保护)、2R-BW(阻燃双塑)、2R-BV(阻燃单塑)，而且等级也有所不同，有国际标准、国家标准、还有些不达标的，其价格相差1-2倍，甚至3-4倍，所以希望消费者不要贪图小便宜，给自己带来麻烦(线管布置要求：照明线和插座线要分开控制，电线为25平方毫米，厨房用电、空调用电以及按摩浴缸等，一定要用专线，电线为4平方毫米。在施工中布线线路一定要上下竖直，电线一定套PVC线管及配件。在线路安装时，一定要严格遵守“火线进开关，零线进灯头左零右火，接地在上”的规定。施工完毕后，除了要通电检查外，施工队还要给户主提供一份详尽的电路配置图。水电安装指导A、把与焊接管材规格相配套的加热端装配到焊接机上，接通电源加热至260度B、把专用剪刀垂直切割管材，切口应平滑无毛刺C、清洁接口出避免沙子灰尘等杂物影响焊接质量D、用铅笔在管材上标出焊接深度E、将管材与管件插入热熔器内，按规定时间进行加热，且不可将管材和管件扭曲或折弯F、加热完毕取出管材与管件进行连接如果两者位置不对，可以在一定时间内做少量调整但扭转角度不得超过5度G、连接完成后必须双手紧握管材与管件压紧至所标的焊接深度，冷却到一定程度后方可松手，整个连接过程完成一般规定电路步线1、本章适用于住宅单相人户配电箱户表后的室内强弱电电路布线及电器、灯具安装。2、配电箱户表后应根据室内用电设备的不同功率分别配线供电；大功率家电设备应独立配线安装插座。3、配线时，相线与零线的颜色应不同；同一住宅相线(L)颜色应统一，零线(N)宜用蓝色，保护线(PE)必须用黄绿双色线。4、导线间和导线对地间电阻必须大于05MΩ。5、各弱电子系统均用星型结构。6、进线穿线管2~3根从户外引入家用信息接入箱。出线穿线管从家用信息箱到各个户内信息插座。所敷设暗管(穿线管)应采用钢管或阻燃硬质聚氯乙烯管(硬质PVC管)。7、直线管的管径利用率应为50%~60%，弯管的管径利用率应为40%~50%。8、所布线路上存在局部干扰源，且不能满足最小净距离要求时，应采用钢管。9、暗管直线敷设长度超过30米，中间应加装过线盒。10、暗管必须弯曲敷设时，其路由长度应≤15米，且该段内不得有S弯。连续弯曲超过2次时，应加装过线盒。所有转弯处均用弯管器完成，为标准的转弯半径。不得采用国家明令禁止的三通四通等。11、暗管弯曲半径不得小于该管外径的6~10倍。12、在暗管孔内不得有各种线缆接头。13、电源线配线时，所用导线截面积应满足用电设备的最大输出功率。14、电线与暖气、热水、煤气管之间的平行距离不应小于300mm，交叉距离不应小于100mm。15、穿入配管导线的接头应设在接线盒内，接头搭接应牢固，涮锡并用绝缘带包缠应均匀紧密。
