电(dian)(dian)力电(dian)(dian)缆用途广泛,种类(lei)繁复。但运(yun)用电(dian)(dian)力电(dian)(dian)缆时,运(yun)用的是绞线。为什么?其(qi)实(shi)绞线用途很(hen)大,起到保护和(he)安全的作用很(hen)重要(yao)。电(dian)(dian)力电(dian)(dian)缆中(zhong)常用的绞线类(lei)型如下:

  1.电(dian)力电(dian)缆一般绞合(he)线(xian):

  电(dian)力(li)电(dian)缆(lan)铝绞线(xian)(LJ):利(li)益:导体重量(liang)轻(qing),导电(dian)性好。用途:用于应力(li)较小的架空电(dian)力(li)线(xian)路(lu)的配电(dian)线(xian)路(lu)。

  电(dian)力电(dian)缆硬铜绞(jiao)线(TJ):利益:电(dian)气性能(neng)优越;用途:架空输(shu)电(dian)线路(lu)。

  电(dian)力电(dian)缆(lan)铝合金绞线(LHAJ):利益:抗(kang)拉强(qiang)度(du)高,导电(dian)率比铝绞线低10%。用途:冰(bing)川、高山、丘陵等(deng)地。

  电(dian)(dian)力(li)电(dian)(dian)缆(lan)铝包钢绞线(xian):利益:抗拉强度高。用(yong)途(tu):大跨度线(xian)。

  2.电(dian)力电(dian)缆组合绞合线:

  电(dian)力(li)电(dian)缆(lan):利益(yi):抗拉强(qiang)度(du)高(gao)。

  用途(tu):架空(kong)输电(dian)线路(lu)、配电(dian)线路(lu)、重冰区(qu)和大跨度输电(dian)线路(lu)。

  电力电缆耐腐(fu)蚀钢芯铝绞线(xian):利益:可防(fang)止(zhi)钢芯腐(fu)蚀,延伸线(xian)材运用的寿数。

  用途(tu):盐湖、滨(bin)海区域、工矿区和腐蚀性(xing)强的(de)区域。

  电力电缆铝(lv)包(bao)钢(gang)芯铝(lv)绞线(xian)(xian)(xian):利益:防(fang)止钢(gang)芯腐蚀,延伸导线(xian)(xian)(xian)运用寿数。减少线(xian)(xian)(xian)损。单位重量减少,导线(xian)(xian)(xian)跨度增加。

  3.电力电缆(lan)特别绞合线:

  电(dian)(dian)力电(dian)(dian)缆直径(jing)加(jia)大的钢芯(xin)铝(lv)绞线(xian):利益:增加(jia)导线(xian)外(wai)径(jing),节约(yue)有色(se)金属,减少电(dian)(dian)晕(yun)损耗。用途:高(gao)压(ya)输电(dian)(dian)和高(gao)空输电(dian)(dian)

  电(dian)(dian)(dian)力电(dian)(dian)(dian)缆(lan)胀大空心(xin)导体(ti):利益:导体(ti)外径较大,减少电(dian)(dian)(dian)晕丢(diu)掉,节约有(you)色(se)金属。用途:高压变电(dian)(dian)(dian)站。

  电(dian)力电(dian)缆消振和空(kong)地扭绞(jiao)线(xian):利益:每一个扭绞(jiao)层(ceng)都是分隔的,可以自(zi)行减少振动。用途:用于暴风雨区域。

  电(dian)力(li)电(dian)缆(lan)防(fang)冰(bing)绞线:利益(yi):防(fang)冰(bing)能(neng)力(li)强(qiang)。用途:重冰(bing)区。

  电力电缆铜刷线:利益(yi):结构安(an)稳,柔韧性好,选用束绞和多次绞制(zhi)而成(cheng)。用途:电机引线。
