先(xian)將兩導(dao)線(xian)芯線(xian)線(xian)頭(tou)成X形相交(jiao)

將支(zhi)路(lu)芯(xin)(xin)線(xian)(xian)(xian)的線(xian)(xian)(xian)頭與干線(xian)(xian)(xian)芯(xin)(xin)線(xian)(xian)(xian)十(shi)字相交，在(zai)支(zhi)路(lu)芯(xin)(xin)線(xian)(xian)(xian)根部留出5mm，然后(hou)順時針方向纏繞6～8圈后(hou)，用鋼(gang)絲鉗切去余下的芯(xin)(xin)線(xian)(xian)(xian)，并鉗平芯(xin)(xin)線(xian)(xian)(xian)末端。

將兩根(gen)雙芯線線頭(tou)剖削成圖示中的(de)(de)形式。連接(jie)(jie)時，將兩根(gen)待(dai)連接(jie)(jie)的(de)(de)線頭(tou)中顏色一致的(de)(de)芯線按小截面直線連接(jie)(jie)方式連接(jie)(jie)。用(yong)相同的(de)(de)方法(fa)將另一顏色的(de)(de)芯線連接(jie)(jie)在(zai)一起。

先將剝去(qu)絕(jue)緣層的(de)(de)芯(xin)(xin)線(xian)頭散開并拉直(zhi)，再把(ba)靠近絕(jue)緣層1/3線(xian)段的(de)(de)芯(xin)(xin)線(xian)絞(jiao)緊，然后把(ba)余下的(de)(de)2/3芯(xin)(xin)線(xian)頭按圖(tu)示(shi)分散成傘狀，并將每根芯(xin)(xin)線(xian)拉直(zhi)。

以7股(gu)(gu)銅(tong)(tong)芯線為例說(shuo)明多股(gu)(gu)銅(tong)(tong)芯導線的T字形連接方法

把3根線(xian)芯(xin)的一組在干線(xian)右(you)邊按順(shun)時針方向緊(jin)緊(jin)纏繞3~4圈，并鉗平線(xian)端；把4根芯(xin)線(xian)的一組在干線(xian)的左邊按逆(ni)時針方向纏繞4~5圈。

單股線(xian)(xian)與多股線(xian)(xian)的T字分支連接

把單股(gu)芯(xin)線(xian)(xian)插(cha)入多(duo)股(gu)芯(xin)線(xian)(xian)的兩(liang)組芯(xin)線(xian)(xian)中間，但單股(gu)芯(xin)線(xian)(xian)不可插(cha)到底，應使絕緣層切(qie)口離多(duo)股(gu)芯(xin)線(xian)(xian)約3mm的距(ju)離。接著(zhu)用(yong)鋼絲鉗(qian)把多(duo)股(gu)芯(xin)線(xian)(xian)的插(cha)縫鉗(qian)平(ping)鉗(qian)緊。

導線用壓接管壓接

將兩根線頭相對(dui)插入(ru)并穿出壓(ya)接管，使兩線端各自伸出壓(ya)接管25~30mm。

如果壓接鋼(gang)芯(xin)鋁絞(jiao)線(xian)(xian)，則應(ying)在(zai)兩(liang)根芯(xin)線(xian)(xian)之間墊(dian)上(shang)一層(ceng)鋁質墊(dian)片。壓接鉗在(zai)壓接管上(shang)的(de)壓坑數目(mu)，室內線(xian)(xian)頭通(tong)常為4個，室外通(tong)常為6個。

連接前，先(xian)用鋼(gang)絲刷除去導(dao)線(xian)(xian)(xian)線(xian)(xian)(xian)頭和溝(gou)線(xian)(xian)(xian)夾(jia)線(xian)(xian)(xian)槽內壁上(shang)的氧化層和污物，涂上(shang)凡士林(lin)鋅膏粉（或中性凡士林(lin)），然后將(jiang)導(dao)線(xian)(xian)(xian)線(xian)(xian)(xian)卡入線(xian)(xian)(xian)槽，旋緊螺(luo)(luo)栓(shuan)，使溝(gou)線(xian)(xian)(xian)夾(jia)緊緊夾(jia)住線(xian)(xian)(xian)頭而完(wan)成連接。為防止螺(luo)(luo)栓(shuan)松動，壓緊螺(luo)(luo)栓(shuan)上(shang)應(ying)套以彈(dan)簧墊圈。
