常用低(di)壓電(dian)力電(dian)纜按絕緣和保護層的不同主(zhu)要可分(fen)為哪幾類

一，電(dian)纜(lan)是用來傳送電(dian)力或信號(hao)電(dian)流、信號(hao)電(dian)壓(ya)(ya)的被(bei)覆有絕緣層(ceng)(ceng)、保護(hu)層(ceng)(ceng)、層(ceng)(ceng)等的導體。按(an)電(dian)壓(ya)(ya)分可為(wei)高壓(ya)(ya)電(dian)纜(lan)和低壓(ya)(ya)電(dian)纜(lan)。低壓(ya)(ya)電(dian)纜(lan)線(xian)(xian)路與低壓(ya)(ya)架空線(xian)(xian)路、低壓(ya)(ya)架空絕緣線(xian)(xian)路相比雖然(ran)造價(jia)較(jiao)高，敷設維護(hu)較(jiao)為(wei)困(kun)難(nan)，但由于它具(ju)有運(yun)行(xing)可靠(kao)、不立電(dian)桿、不占地面、不礙觀瞻、受外界影響(xiang)較(jiao)小等特點(dian)，而在低壓(ya)(ya)配電(dian)系統(tong)中(zhong)得(de)到廣泛應(ying)用。

二(er)，低壓(ya)電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)由(you)線(xian)芯(xin)、絕緣層和保護層三(san)部分構成(cheng)(cheng)。線(xian)芯(xin)用(yong)于(yu)傳導電(dian)(dian)(dian)(dian)(dian)流， 一般由(you)多股(gu)銅線(xian)或多股(gu)鋁(lv)線(xian)絞合而成(cheng)(cheng)。低壓(ya)電(dian)(dian)(dian)(dian)(dian)纜(lan)有單芯(xin)、雙芯(xin)、三(san)芯(xin)、四(si)芯(xin)等幾種。雙芯(xin)電(dian)(dian)(dian)(dian)(dian)纜(lan)用(yong)于(yu)單相線(xian)路(lu)，三(san)芯(xin)和四(si)芯(xin)電(dian)(dian)(dian)(dian)(dian)纜(lan)分別(bie)用(yong)于(yu)三(san)相三(san)線(xian)制(zhi)線(xian)路(lu)和三(san)相四(si)線(xian)制(zhi)線(xian)路(lu)， 單芯(xin)電(dian)(dian)(dian)(dian)(dian)纜(lan)可以按需要(yao)應用(yong)于(yu)單相制(zhi)線(xian)路(lu)或三(san)相制(zhi)線(xian)路(lu)。常用(yong)的低壓(ya)電(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)芯(xin)截面積有10，16， 25， 35， 50， 70， 95， 120，150， 185， 240 mm等。

三，常用按絕緣和保護層的不同，主要可分為哪幾類？
