鐵氟龍線增加電阻的法子
鐵氟龍(long)線(xian)(xian)是(shi)(shi)以聚(ju)四氟乙(yi)烯(xi)俗稱氟塑料(liao)為絕緣，包(bao)裹金屬導(dao)體而(er)成的(de)(de)電(dian)(dian)線(xian)(xian)。高(gao)溫(wen)電(dian)(dian)線(xian)(xian)大(da)多(duo)數選用(yong)鋁紋線(xian)(xian)特別是(shi)(shi)大(da)量應用(yong)用(yong)芯鋁(或鋁合(he)金)絞線(xian)(xian)等(deng)復合(he)材料(liao)的(de)(de)導(dao)體，其鋼芯主(zhu)要接受機械拉力，而(er)由(you)一層或多(duo)層鋁線(xian)(xian)絞合(he)的(de)(de)部分則接受導(dao)電(dian)(dian)效果。鐵氟龍(long)線(xian)(xian)的(de)(de)電(dian)(dian)阻增加(jia)，盡管(guan)高(gao)溫(wen)電(dian)(dian)線(xian)(xian)各層紋合(he)節矩方向相反(fan)、節大(da)小(xiao)不等(deng)，但殘存的(de)(de)磁場強度(du)一般
