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(dian)纜終端頭。電(dian)(dian)纜終端(duan)(duan)頭(tou)(tou)集防(fang)水(shui)、應力控制、屏蔽、絕緣于一體，具有良好的(de)電(dian)(dian)氣性能(neng)和機械性能(neng)，能(neng)在(zai)各種(zhong)惡劣的(de)環境條件下長期使用。具有重量輕、安裝方便等優點。電(dian)(dian)纜終端(duan)(duan)頭(tou)(tou)廣泛應用于電(dian)(dian)力、石油化工、冶(ye)金、鐵路港口和建筑等各個(ge)領域(yu)。

二、電纜終端頭的作用

電纜終端(duan)頭作用(yong)是(shi)裝配到電纜線路的首(shou)末端(duan)，用(yong)以(yi)完(wan)成與(yu)其(qi)他電氣(qi)設備連接的裝置，有戶外(wai)終端(duan)頭、戶內終端(duan)頭、肘形終端(duan)頭等。

電(dian)(dian)(dian)(dian)纜終(zhong)端頭均勻電(dian)(dian)(dian)(dian)纜末(mo)端電(dian)(dian)(dian)(dian)場(chang)分(fen)布(bu)，實現(xian)電(dian)(dian)(dian)(dian)應力(li)的(de)(de)有效控(kong)制。電(dian)(dian)(dian)(dian)應力(li)控(kong)制就是(shi)指(zhi)對電(dian)(dian)(dian)(dian)場(chang)分(fen)布(bu)及(ji)(ji)電(dian)(dian)(dian)(dian)場(chang)強度的(de)(de)控(kong)制，采取適當(dang)的(de)(de)措施，使電(dian)(dian)(dian)(dian)場(chang)分(fen)布(bu)及(ji)(ji)電(dian)(dian)(dian)(dian)場(chang)強度處(chu)于最佳(jia)狀態，使電(dian)(dian)(dian)(dian)場(chang)分(fen)布(bu)盡可(ke)能均勻，提高電(dian)(dian)(dian)(dian)纜運(yun)行的(de)(de)可(ke)靠性。

三、電纜終端頭的分類

1、按(an)安裝(zhuang)材料分為熱縮電纜終(zhong)端頭和冷縮電纜終(zhong)端頭。

2、按(an)工(gong)作電(dian)(dian)(dian)壓分為(wei)1KV電(dian)(dian)(dian)纜頭、10KV電(dian)(dian)(dian)纜頭、27.5KV電(dian)(dian)(dian)纜頭、35KV電(dian)(dian)(dian)纜頭、66KV電(dian)(dian)(dian)纜頭、110KV電(dian)(dian)(dian)纜頭、138KV電(dian)(dian)(dian)纜頭、220KV電(dian)(dian)(dian)纜頭。

3、按使用條件分為分為戶(hu)內電(dian)(dian)纜(lan)終端頭(tou)(tou)和(he)戶(hu)外電(dian)(dian)纜(lan)終端頭(tou)(tou)。

4、按芯(xin)數(shu)分為(wei)單芯(xin)終(zhong)端(duan)頭(tou)、兩(liang)芯(xin)終(zhong)端(duan)頭(tou)、三芯(xin)終(zhong)端(duan)頭(tou)、四(si)芯(xin)終(zhong)端(duan)頭(tou)（又分為(wei)四(si)等(deng)芯(xin)和(he)3+1）、五(wu)芯(xin)終(zhong)端(duan)頭(tou)（又分為(wei)五(wu)等(deng)芯(xin)、3+2和(he)4+1）。
