1)剝(bo)切(qie)銅(tong)屏(ping)蔽(bi)層。冷(leng)縮護套管端口(kou)(kou)向上量取30mm銅(tong)屏(ping)蔽(bi)，其(qi)余剝(bo)除(chu)，為防止銅(tong)屏(ping)蔽(bi)帶松散(san)，可在纜芯適當位置用絕緣自(zi)粘帶扎緊。切(qie)割處(chu)用絕緣自(zi)粘帶或細銅(tong)線(xian)扎緊，切(qie)割時，只(zhi)能環切(qie)一刀痕，約2/3深度，不能切(qie)穿(chuan)，以免損傷(shang)半導(dao)電(dian)層。剝(bo)除(chu)銅(tong)屏(ping)蔽(bi)時，應(ying)以刀痕處(chu)撕剝(bo)，斷開后向線(xian)芯端部剝(bo)除(chu)。銅(tong)屏(ping)蔽(bi)層的端口(kou)(kou)應(ying)切(qie)割平整，不得有尖(jian)端和(he)毛刺(ci)。

2)剝切(qie)外(wai)半(ban)(ban)導(dao)(dao)電(dian)(dian)屏蔽(bi)(bi)層。自銅屏蔽(bi)(bi)層端口向上量取10mm半(ban)(ban)導(dao)(dao)電(dian)(dian)屏蔽(bi)(bi)層，.其余(yu)剝除(chu)。剝切(qie)外(wai)半(ban)(ban)導(dao)(dao)電(dian)(dian)，環切(qie)及縱切(qie)刀(dao)痕，不能切(qie)穿(chuan)，以免損傷主絕緣。外(wai)半(ban)(ban)導(dao)(dao)電(dian)(dian)層應(ying)剝除(chu)干(gan)凈，不得(de)留有(you)殘跡，剝除(chu)后必(bi)須用細砂(sha)紙將(jiang)絕緣表(biao)(biao)面吸附的(de)半(ban)(ban)導(dao)(dao)電(dian)(dian)粉塵砂(sha)磨干(gan)凈并使絕緣層表(biao)(biao)面清洗光(guang)潔(jie)。

3)絕(jue)(jue)緣端部應力(li)處理(li)。將(jiang)外(wai)半(ban)(ban)導(dao)電層(ceng)(ceng)及絕(jue)(jue)緣體末端用砂紙打磨(mo)或刀具切割倒角，并打磨(mo)光潔，與絕(jue)(jue)緣圓(yuan)滑過渡(du)。繞包(bao)兩層(ceng)(ceng)半(ban)(ban)導(dao)電帶將(jiang)銅屏蔽層(ceng)(ceng)與外(wai)半(ban)(ban)導(dao)電層(ceng)(ceng)之間的臺階蓋(gai)住(zhu)。在冷(leng)縮(suo)套管管口往下6mm的地方包(bao)繞一層(ceng)(ceng)防水膠。
