1)剝除(chu)線(xian)芯(xin)末端絕(jue)緣。用清(qing)沽紙清(qing)潔(jie)電纜(lan)絕(jue)緣表面(mian)，清(qing)潔(jie)時，從線(xian)芯(xin)端頭向(xiang)外半導(dao)層方向(xiang)擦(ca)拭，切(qie)不(bu)可(ke)來回擦(ca)。剝除(chu)線(xian)芯(xin)末端絕(jue)緣的(de)(de)長度為接線(xian)端子的(de)(de)孔深加5mm。剝除(chu)線(xian)芯(xin)絕(jue)緣時，不(bu)得(de)(de)損傷線(xian)芯(xin)導(dao)體，應順著(zhu)導(dao)線(xian)絞合方向(xiang)進行(xing)，不(bu)得(de)(de)使導(dao)體松散變(bian)形。

2)安(an)裝(zhuang)終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)。在三相分支手套口往下25mm處，繞包絕緣(yuan)帶作標識，此處作為(wei)終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)安(an)裝(zhuang)基準(zhun)。將硅脂涂在線芯表面(多涂)，套人冷縮(suo)式終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)，用力將終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)套入，慢慢拉(la)動終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)內的支撐條，直至終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)下端(duan)(duan)口與標識對齊(qi)為(wei)止(zhi)，不得(de)超出標識。冷縮(suo)終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)從根部(bu)向絕緣(yuan)端(duan)(duan)部(bu)收縮(suo)，逆時(shi)針輕輕拉(la)動支撐條，使(shi)冷縮(suo)管收縮(suo)(如開始收縮(suo)時(shi)發(fa)現(xian)終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)和標識錯位，可用手把它糾(jiu)正過來(lai))。收縮(suo)要均勻，不能用力過大，以免造成附(fu)件損壞。在終(zhong)(zhong)(zhong)(zhong)端(duan)(duan)與冷縮(suo)護套管搭界(jie)處，必(bi)須繞包幾層絕緣(yuan)自粘(zhan)膠帶，加強密封(feng)。
