電(dian)(dian)纜(lan)保(bao)護(hu)(hu)管(guan)(guan)又名(ming)電(dian)(dian)纜(lan)管(guan)(guan)、電(dian)(dian)力(li)電(dian)(dian)纜(lan)管(guan)(guan)、水泥電(dian)(dian)纜(lan)管(guan)(guan)、電(dian)(dian)力(li)排(pai)管(guan)(guan)、電(dian)(dian)力(li)電(dian)(dian)纜(lan)保(bao)護(hu)(hu)管(guan)(guan)等。電(dian)(dian)纜(lan)保(bao)護(hu)(hu)管(guan)(guan)主要安裝在通訊電(dian)(dian)纜(lan)與(yu)電(dian)(dian)力(li)線(xian)交叉的(de)地(di)段(duan)，防(fang)止電(dian)(dian)力(li)線(xian)發生斷線(xian)造成(cheng)短路事故，引起通訊電(dian)(dian)纜(lan)和鋼絲繩帶電(dian)(dian)，以(yi)保(bao)護(hu)(hu)電(dian)(dian)纜(lan)、交換(huan)機、機芯板(ban)，以(yi)至(zhi)整機不(bu)被燒壞(huai)，對(dui)電(dian)(dian)力(li)線(xian)磁場干擾也起到一定的(de)隔離作用。對(dui)于時(shi)代(dai)的(de)發展，水泥制作或(huo)者(zhe)其他(ta)非金(jin)屬制作的(de)復合(he)材料(liao)都逐漸被玻璃(li)鋼所代(dai)替，大多數采用玻璃(li)鋼制作的(de)電(dian)(dian)纜(lan)保(bao)護(hu)(hu)管(guan)(guan)可以(yi)提高它在地(di)下的(de)耐腐蝕性(xing)能和壽命(ming)，擁(yong)有光滑的(de)表面，在清洗方(fang)面性(xing)能都很(hen)突出(chu)等。
