電纜(lan)(lan)(lan)附件(jian)的連(lian)(lian)接方式一般(ban)分為終(zhong)端連(lian)(lian)接及中間連(lian)(lian)接，終(zhong)端連(lian)(lian)接分為戶內(nei)終(zhong)端和戶外終(zhong)端，一般(ban)情(qing)況戶外終(zhong)端是(shi)指(zhi)露天(tian)電纜(lan)(lan)(lan)接頭，通遼電纜(lan)(lan)(lan)頭，戶內(nei)終(zhong)端是(shi)指(zhi)室內(nei)連(lian)(lian)接電纜(lan)(lan)(lan)與(yu)電氣設(she)備的接頭;中間連(lian)(lian)接分為直(zhi)通式和絕(jue)緣式兩種.

電纜附(fu)件的(de)種類繁多，具有(you)不同類型的(de)特(te)點(dian)及局限性，一般不能相(xiang)互(hu)取代。常見(jian)的(de)有(you)如下幾種

繞包式(shi)(shi)(shi) 冷(leng)縮式(shi)(shi)(shi) 熱縮式(shi)(shi)(shi)  預制式(shi)(shi)(shi)

中低壓電纜附(fu)(fu)件(jian)使用得比較多的產(chan)品種類(lei)主要有(you)熱縮(suo)(suo)附(fu)(fu)件(jian)、預制(zhi)式附(fu)(fu)件(jian)、冷縮(suo)(suo)附(fu)(fu)件(jian)

電纜終端頭發熱(re)的原因

一些電(dian)(dian)氣安裝施工人員在(zai)敷設電(dian)(dian)線(xian)時，往往不(bu)(bu)注意(yi)安裝質量:在(zai)應該(gai)用(yong)絕緣套(tao)管處(chu)不(bu)(bu)裝套(tao)管;應該(gai)用(yong)接(jie)(jie)線(xian)盒的(de)(de)地方(fang)(fang)也沒(mei)有裝接(jie)(jie)線(xian)盒;甚至在(zai)電(dian)(dian)線(xian)接(jie)(jie)頭處(chu)不(bu)(bu)是采用(yong)絞接(jie)(jie)方(fang)(fang)法，而是采用(yong)的(de)(de)彎鉤狀連(lian)接(jie)(jie)方(fang)(fang)法。這(zhe)種(zhong)彎鉤狀連(lian)接(jie)(jie)方(fang)(fang)法的(de)(de)接(jie)(jie)觸電(dian)(dian)阻很大，通電(dian)(dian)時不(bu)(bu)斷發(fa)熱，會使附近的(de)(de)木(mu)板逐(zhu)步干(gan)燥、炭化，后發(fa)生燃燒，引起火災。

母(mu)(mu)線是匯(hui)集電流(liu)用的(de)。很(hen)多電源與供電回路(lu)都(dou)接在母(mu)(mu)線上(shang)，通過母(mu)(mu)線將電力匯(hui)集并送(song)到(dao)各回路(lu)上(shang)去。所(suo)以母(mu)(mu)線的(de)載(zai)流(liu)量要(yao)求比較(jiao)大，冷縮電纜頭，母(mu)(mu)線的(de)截面較(jiao)大，因此(ci)母(mu)(mu)線一般都(dou)采用裸母(mu)(mu)線型式；

電(dian)纜是輸送(song)電(dian)纜用(yong)的(de)，10kv電(dian)纜頭制作，從電(dian)源向較(jiao)長距離的(de)負荷送(song)電(dian)，有一(yi)部分采用(yong)電(dian)纜的(de)型式(shi)(shi)。電(dian)纜的(de)載流量相對比較(jiao)小，采用(yong)絕緣方式(shi)(shi)，可(ke)以敷設在地(di)下、溝(gou)道及架空構架上

中(zhong)(zhong)國(guo)經濟持續快(kuai)速(su)的(de)(de)增長，為線(xian)纜(lan)(lan)產(chan)品提(ti)供了巨大的(de)(de)市(shi)場空間，電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)頭，中(zhong)(zhong)國(guo)市(shi)場強烈的(de)(de)力，使得世界(jie)(jie)都把目光聚焦于中(zhong)(zhong)國(guo)市(shi)場，在改(gai)革開放短短的(de)(de)幾十年(nian)，中(zhong)(zhong)國(guo)線(xian)纜(lan)(lan)制造(zao)業(ye)所(suo)形成的(de)(de)龐大生產(chan)能力讓(rang)世界(jie)(jie)刮目相看。隨(sui)著中(zhong)(zhong)國(guo)電(dian)(dian)(dian)(dian)力工業(ye)、數(shu)據通(tong)信業(ye)、城市(shi)軌道交通(tong)業(ye)、汽(qi)車業(ye)以及造(zao)船等行業(ye)規模的(de)(de)不斷擴(kuo)大，對(dui)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)需(xu)求也將迅(xun)速(su)增長，未來電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)業(ye)還有巨大的(de)(de)發展潛力。耐火電(dian)(dian)(dian)(dian)纜(lan)(lan)2008年(nian)11月，我(wo)國(guo)為應對(dui)世界(jie)(jie)金(jin)融(rong)危機(ji)，決定(ding)投入4萬億元拉動內需(xu)，其中(zhong)(zhong)有大約40%以上(shang)用(yong)于城鄉電(dian)(dian)(dian)(dian)網(wang)建(jian)(jian)設與改(gai)造(zao)。電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)行業(ye)又有了良好的(de)(de)市(shi)場機(ji)遇，各(ge)地電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)企業(ye)抓住機(ji)遇，迎接(jie)新一輪城鄉電(dian)(dian)(dian)(dian)網(wang)建(jian)(jian)設與改(gai)造(zao)。
