廣州電線電纜的區別大致可以分為三大類
廣州電線電纜已成(cheng)為(wei)人類生(sheng)活、生(sheng)產不可缺少的(de)工具(ju),但仍有許多(duo)人無法分辨(bian)什(shen)么是(shi)電(dian)(dian)(dian)線、電(dian)(dian)(dian)纜。即使有人認為(wei)電(dian)(dian)(dian)線和電(dian)(dian)(dian)纜是(shi)一回事,其實(shi)想(xiang)一想(xiang),既然產品分為(wei)電(dian)(dian)(dian)線、電(dian)(dian)(dian)纜兩類,這(zhe)就解釋了電(dian)(dian)(dian)線和電(dian)(dian)(dian)纜有區(qu)別。
電(dian)線與電(dian)纜,不僅在結構(gou)上有(you)差異,其用途(tu)也有(you)很大(da)的不同,而電(dian)線和電(dian)纜的區別(bie)大(da)致可(ke)以(yi)分(fen)為三大(da)類:材(cai)料、用途(tu)、結構(gou)。
先從材料(liao)的(de)選擇和使用上,導(dao)(dao)線(xian)是用導(dao)(dao)電金屬線(xian)來承載電流,有實體(ti)(ti)、絞線(xian),此外(wai),還可(ke)以用箔紙編織等多種形(xing)式,并且(qie)電纜(lan)是由一個或多個互相絕緣的(de)導(dao)(dao)體(ti)(ti)放在密封外(wai)殼中(zhong)組成的(de)絕緣導(dao)(dao)線(xian)。它的(de)外(wai)面(mian)常常會加一層(ceng)(ceng)保(bao)護(hu)層(ceng)(ceng),根據其材質的(de)不同,造成其外(wai)觀差異,線(xian)材通常大小不一,而且(qie)有些多芯的(de)電纜(lan)比(bi)較粗。
第二,電(dian)線(xian)(xian)(xian)與電(dian)纜的(de)(de)區別在于用(yong)途不(bu)(bu)同,有一種裸線(xian)(xian)(xian),即不(bu)(bu)帶(dai)任(ren)何絕(jue)緣或保護層的(de)(de)導(dao)線(xian)(xian)(xian),既可作為傳遞電(dian)能、傳遞信息的(de)(de)導(dao)線(xian)(xian)(xian),又可作為各種小型電(dian)器部件(jian)的(de)(de)連接線(xian)(xian)(xian),常(chang)用(yong)的(de)(de)裸絲有銅(tong)、鋁(lv)、銅(tong)合(he)金(jin)、鋁(lv)材等,而各種絕(jue)緣導(dao)線(xian)(xian)(xian)在日常(chang)生活中(zhong)更(geng)是(shi)隨處可見,家中(zhong)的(de)(de)線(xian)(xian)(xian)路多(duo)采用(yong)絕(jue)緣線(xian)(xian)(xian),而實際生產中(zhong),如電(dian)動機用(yong)電(dian)器引接線(xian)(xian)(xian)、航(hang)空(kong)導(dao)線(xian)(xian)(xian)、補(bu)償(chang)導(dao)線(xian)(xian)(xian)等也采用(yong)絕(jue)緣導(dao)線(xian)(xian)(xian)。
電纜(lan)(lan)結構(gou)(gou)和(he)性能更為復雜,應用也越來(lai)越廣泛,根據不(bu)同的用途,特(te)點分為電力電纜(lan)(lan)、通訊電纜(lan)(lan)、控(kong)制電纜(lan)(lan)、專(zhuan)用電纜(lan)(lan)等(deng)。線(xian)纜(lan)(lan)通常要比線(xian)材尺寸大(da),而(er)且結構(gou)(gou)更為復雜,線(xian)材主要由(you)四(si)個部分組成(cheng):導體、絕緣層、密(mi)封外殼(ke)和(he)保護(hu)層。
由于結構(gou)及特點(dian)的(de)不(bu)(bu)(bu)同,電纜可(ke)謂(wei)是優勢明(ming)顯,與架空(kong)線路相比,廣州電纜的(de)優點(dian)在(zai)于線間絕(jue)緣(yuan)距(ju)離小,占用空(kong)間小,在(zai)地(di)(di)下敷設,不(bu)(bu)(bu)占地(di)(di)面(mian)以(yi)(yi)上空(kong)間,不(bu)(bu)(bu)受周(zhou)圍(wei)環(huan)境(jing)污染(ran)影響,送電可(ke)靠性高,對人(ren)身安全和周(zhou)圍(wei)環(huan)境(jing)干擾(rao)小。所以(yi)(yi),電纜多用于人(ren)口密度大、電網密度大的(de)地(di)(di)區(qu)和交通繁忙(mang)的(de)地(di)(di)方。在(zai)現代(dai)化建設中(zhong)起著不(bu)(bu)(bu)容(rong)忽(hu)視的(de)作用。
