今朝，局部用戶和檢測機構在電纜標稱截面積丈量的懂得上存在一些誤區，將標稱截面積懂得為規范劃定的截面積，接納多少法丈量導體的現實橫截面積并依此停止鑒定，致使局部合適產物規范請求的電線電纜在交貨抽檢時被鑒定分歧格。比方用于電器電源線的通俗聚氯乙烯軟線60227 IEC 53(RVV) 300/500V 3X0.75產物(wu)，標稱截(jie)(jie)面(mian)積為(wei)(wei)0.75 mm2，實測截(jie)(jie)面(mian)積為(wei)(wei)0.72 mm2，比標稱橫截(jie)(jie)面(mian)小了0.03 mm2，即便其導(dao)體電(dian)(dian)(dian)阻(zu)合適標稱截(jie)(jie)面(mian)積為(wei)(wei)0.75 mm2的(de)產物(wu)規(gui)范請(qing)求，仍被誤判(pan)為(wei)(wei)分(fen)歧(qi)格產物(wu)，終(zhong)究在線(xian)纜及(ji)零(ling)件(jian)產物(wu)的(de)發賣和驗收上，給企(qi)業和用(yong)戶方均帶(dai)來攪擾(rao)和不良影(ying)響。為(wei)(wei)此，本文對電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜導(dao)體的(de)標稱截(jie)(jie)面(mian)積停止詮(quan)釋和申(shen)明，但愿有(you)助各方精確懂得標稱截(jie)(jie)面(mian)積，削減曲解及(ji)誤判(pan)，并迷信精確地利用(yong)電(dian)(dian)(dian)阻(zu)法來查核導(dao)體截(jie)(jie)面(mian)積。Rb2拖(tuo)(tuo)鏈(lian)拖(tuo)(tuo)鏈(lian)電(dian)(dian)(dian)線(xian)拖(tuo)(tuo)鏈(lian)電(dian)(dian)(dian)線(xian)-聚氨脂圈筒拖(tuo)(tuo)鏈(lian)電(dian)(dian)(dian)線(xian)-高柔軟坦克鏈(lian)拖(tuo)(tuo)鏈(lian)電(dian)(dian)(dian)線(xian)企(qi)業

今朝電線電纜各大支流規范系統的產物規范均接納標稱截面積或規格代號來對應辨別差別截面的導體。比方IEC規范（IEC60227、IEC60245、IEC60502等）、歐洲規范（EN50525等）和國度規范（GB/T5013、GB/T5023、GB/T12706等）接納標稱截面積（單元：平方毫米）作為差別截面導體規格的代號，美國標準（UL758、UL62 等）則接納AWG規(gui)格作為代號。此中(zhong)，對差別截(jie)(jie)面規(gui)格代號的(de)查核(he)均是經由進程導體電(dian)(dian)(dian)(dian)(dian)阻(zu)值(zhi)來請求(qiu)，而非現實丈量(liang)導體截(jie)(jie)面積（注(zhu)：UL 規(gui)范許可丈量(liang)現實截(jie)(jie)面積，但接納(na)導體電(dian)(dian)(dian)(dian)(dian)阻(zu)作為仲裁方式(shi)）。Rb2拖(tuo)鏈電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)-聚氨酯泡沫鋼絲繩卷筒電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)-高被動式(shi)坦(tan)克鏈電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)工廠

在GB/T3956中，導體共分四種：第1種（實心導體）、第2種（絞合導體）、第5種（軟導體）和第6種（比第5種更柔嫩的導體）。此中，第1種和第2種導體用于牢固敷設的電纜中（比方布電線、電力電纜等）。第5種和第6種導體用于軟電纜和(he)軟線(xian)(xian)中（比方電源線(xian)(xian)、橡套電纜(lan)等），也可用于牢固敷(fu)設。Rb2線(xian)(xian)纜(lan)拖鏈線(xian)(xian)纜(lan)-聚(ju)胺脂卷簡線(xian)(xian)纜(lan)-高槽式坦克鏈線(xian)(xian)纜(lan)商(shang)家
