常(chang)用的電(dian)纜分(fen)類分(fen)為(wei)五大類：

(1) 電線(xian)與裸內(nei)導(dao)體(ti)(ti)制品：指(zhi)僅有(you)導(dao)體(ti)(ti)，而無絕緣層和其它(ta)結構。如：銅、鋁及(ji)各(ge)種(zhong)復合金屬單線(xian);各(ge)種(zhong)結構的(de)架空傳輸用絞線(xian)、軟接線(xian)、型(xing)線(xian)和型(xing)材等等。

(2) 電(dian)(dian)磁(ci)線(xian)(xian)(xian)：以繞組的形式在磁(ci)場中切割磁(ci)力線(xian)(xian)(xian)感應產(chan)生電(dian)(dian)流(liu)，或通過以電(dian)(dian)流(liu)1產(chan)生磁(ci)場作用的電(dian)(dian)線(xian)(xian)(xian)稱為電(dian)(dian)磁(ci)線(xian)(xian)(xian)。如漆(qi)包線(xian)(xian)(xian)、纖維繞包線(xian)(xian)(xian)、無機絕緣線(xian)(xian)(xian)等等。

(3) 電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜：在電(dian)(dian)(dian)(dian)力系統的(de)主干(gan)線路中(zhong)用以(yi)傳輸和(he)分配大功(gong)率電(dian)(dian)(dian)(dian)能的(de)電(dian)(dian)(dian)(dian)線產品，稱為電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜。如：各種電(dian)(dian)(dian)(dian)壓等(deng)級(ji)的(de)塑力纜、油浸紙電(dian)(dian)(dian)(dian)纜和(he)不(bu)滴流等(deng)等(deng)。

(4) 通信(xin)電(dian)纜(lan)(lan)：傳輸音(yin)頻和(he)音(yin)頻以上各種電(dian)訊信(xin)息用的電(dian)纜(lan)(lan)。如：市話(hua)電(dian)纜(lan)(lan)、長(chang)途(tu)對稱通信(xin)電(dian)纜(lan)(lan)、同軸通信(xin)電(dian)纜(lan)(lan)、電(dian)話(hua)設(she)備用電(dian)纜(lan)(lan)和(he)數據電(dian)纜(lan)(lan)等等。

(5) 電(dian)氣(qi)(qi)裝(zhuang)備用(yong)(yong)電(dian)線(xian)電(dian)纜：從電(dian)力系統的(de)配(pei)電(dian)點把電(dian)能(neng)直接(jie)傳(chuan)送到(dao)各種(zhong)用(yong)(yong)電(dian)設(she)備、器具的(de)電(dian)源連接(jie)用(yong)(yong)電(dian)線(xian)電(dian)纜。如：各種(zhong)工農業裝(zhuang)備中(zhong)的(de)電(dian)氣(qi)(qi)連接(jie)和控(kong)制信號用(yong)(yong)的(de)電(dian)線(xian)電(dian)纜。這類產品(pin)使用(yong)(yong)面廣、品(pin)種(zhong)繁(fan)多(duo)，電(dian)纜，而且大多(duo)要結(jie)合所用(yong)(yong)裝(zhuang)備的(de)特征和使用(yong)(yong)的(de)環境條件(jian)來(lai)確定產品(pin)的(de)結(jie)構(gou)、性能(neng)。

電線(xian)電纜安全用電小常(chang)識:

（1）電線電纜(lan)線路以及絕緣部分(fen)必(bi)須(xu)保持通順及良好，電纜(lan)廠家地(di)址，并(bing)定期按時檢查；

（2）插座、開(kai)關(guan)等(deng)(deng)處的電線(xian)決(jue)不(bu)能外漏(lou)，以防漏(lou)電、觸(chu)電等(deng)(deng)；

（3）不能亂(luan)拉亂(luan)接(jie)，多(duo)大平(ping)方的電(dian)線(xian)能帶多(duo)大的電(dian)流、額(e)定(ding)電(dian)壓(ya)多(duo)少，都是固定(ding)的，因此，隨便亂(luan)拉亂(luan)接(jie)電(dian)線(xian)，電(dian)纜生產廠(chang)家，極易造(zao)成超負荷運行，發生短路等(deng)事故。

（4）不要站在超(chao)市的地面上移動(dong)或(huo)觸(chu)碰(peng)帶電物體或(huo)者電線絕緣破損處，以防(fang)觸(chu)電。

（5）總閘處保(bao)險絲的(de)選用要合理(li)，不允許(xu)使用銅絲、鋁絲或鐵絲來代替。
