一、電纜終端頭是什么

電纜鋪設好后，為了使其成為一個連續的線路，各段線必須連接為一個整體，這些連接點就稱為電纜接頭，線路兩末端的電纜接頭稱為電纜(lan)終端頭。電(dian)纜終(zhong)端頭(tou)集(ji)防水、應(ying)(ying)力控制(zhi)、屏蔽(bi)、絕(jue)緣于一體(ti)，具有(you)良(liang)好的(de)電(dian)氣性(xing)能(neng)和機械性(xing)能(neng)，能(neng)在(zai)各種(zhong)惡劣(lie)的(de)環境條件下長期(qi)使用(yong)。具有(you)重(zhong)量輕、安(an)裝方(fang)便等優點。電(dian)纜終(zhong)端頭(tou)廣泛應(ying)(ying)用(yong)于電(dian)力、石油(you)化工、冶金、鐵路(lu)港口和建筑等各個領(ling)域。

二、電纜終端頭的作用

電(dian)(dian)纜(lan)終(zhong)(zhong)端頭作用是裝配到電(dian)(dian)纜(lan)線路的首(shou)末端，用以(yi)完成(cheng)與其他電(dian)(dian)氣(qi)設(she)備(bei)連接的裝置，有戶(hu)外(wai)終(zhong)(zhong)端頭、戶(hu)內終(zhong)(zhong)端頭、肘(zhou)形(xing)終(zhong)(zhong)端頭等(deng)。

電(dian)(dian)(dian)(dian)纜(lan)終端頭均(jun)勻電(dian)(dian)(dian)(dian)纜(lan)末端電(dian)(dian)(dian)(dian)場(chang)分(fen)(fen)布(bu)(bu)(bu)，實現電(dian)(dian)(dian)(dian)應力(li)的(de)有效控(kong)制。電(dian)(dian)(dian)(dian)應力(li)控(kong)制就是指對電(dian)(dian)(dian)(dian)場(chang)分(fen)(fen)布(bu)(bu)(bu)及(ji)(ji)電(dian)(dian)(dian)(dian)場(chang)強(qiang)度的(de)控(kong)制，采取適(shi)當的(de)措施，使電(dian)(dian)(dian)(dian)場(chang)分(fen)(fen)布(bu)(bu)(bu)及(ji)(ji)電(dian)(dian)(dian)(dian)場(chang)強(qiang)度處于最佳狀(zhuang)態，使電(dian)(dian)(dian)(dian)場(chang)分(fen)(fen)布(bu)(bu)(bu)盡可能均(jun)勻，提高電(dian)(dian)(dian)(dian)纜(lan)運(yun)行(xing)的(de)可靠性(xing)。

三、電纜終端頭的分類

1、按安裝材(cai)料分為熱縮(suo)電纜(lan)終(zhong)端(duan)頭和冷縮(suo)電纜(lan)終(zhong)端(duan)頭。

2、按工作電(dian)(dian)壓分為(wei)1KV電(dian)(dian)纜(lan)(lan)頭(tou)(tou)(tou)(tou)、10KV電(dian)(dian)纜(lan)(lan)頭(tou)(tou)(tou)(tou)、27.5KV電(dian)(dian)纜(lan)(lan)頭(tou)(tou)(tou)(tou)、35KV電(dian)(dian)纜(lan)(lan)頭(tou)(tou)(tou)(tou)、66KV電(dian)(dian)纜(lan)(lan)頭(tou)(tou)(tou)(tou)、110KV電(dian)(dian)纜(lan)(lan)頭(tou)(tou)(tou)(tou)、138KV電(dian)(dian)纜(lan)(lan)頭(tou)(tou)(tou)(tou)、220KV電(dian)(dian)纜(lan)(lan)頭(tou)(tou)(tou)(tou)。

3、按(an)使用條(tiao)件(jian)分為分為戶內(nei)電纜(lan)終端(duan)(duan)頭和戶外(wai)電纜(lan)終端(duan)(duan)頭。

4、按芯(xin)(xin)數分為(wei)單芯(xin)(xin)終端(duan)頭(tou)、兩芯(xin)(xin)終端(duan)頭(tou)、三芯(xin)(xin)終端(duan)頭(tou)、四芯(xin)(xin)終端(duan)頭(tou)（又分為(wei)四等芯(xin)(xin)和(he)3+1）、五芯(xin)(xin)終端(duan)頭(tou)（又分為(wei)五等芯(xin)(xin)、3+2和(he)4+1）。
