1)剝切(qie)(qie)銅(tong)(tong)屏(ping)蔽層。在距端(duan)頭300mm處(chu)剝除銅(tong)(tong)屏(ping)蔽層，為防(fang)止(zhi)銅(tong)(tong)屏(ping)蔽帶(dai)(dai)松(song)散，可(ke)在纜芯適當位(wei)置用絕(jue)緣自粘帶(dai)(dai)扎緊。剝銅(tong)(tong)屏(ping)蔽時，切(qie)(qie)割處(chu)用絕(jue)緣自粘帶(dai)(dai)或細銅(tong)(tong)線扎緊，切(qie)(qie)割時，只(zhi)能環切(qie)(qie)一刀(dao)(dao)痕，約2/3深度(du)，不能切(qie)(qie)穿，以免損(sun)傷半(ban)導電層。剝除銅(tong)(tong)屏(ping)蔽時，應以刀(dao)(dao)痕處(chu)撕剝，斷開后(hou)向線芯端(duan)部剝除。銅(tong)(tong)屏(ping)蔽層的端(duan)口應切(qie)(qie)割平(ping)整，不得有尖(jian)端(duan)和毛刺。

2)剝切外(wai)半(ban)導(dao)電(dian)(dian)層(ceng)。在(zai)距銅屏(ping)蔽端口50mm處剝除(chu)外(wai)半(ban)導(dao)電(dian)(dian)屏(ping)蔽層(ceng)。剝切外(wai)半(ban)導(dao)電(dian)(dian)，環切及(ji)縱(zong)切刀痕，不能切穿，以免損傷主(zhu)絕(jue)緣(yuan)。外(wai)半(ban)導(dao)電(dian)(dian)層(ceng)應剝除(chu)干凈，不得留有殘跡，剝除(chu)后必須用細砂紙將絕(jue)緣(yuan)表面吸附的半(ban)導(dao)電(dian)(dian)粉塵砂磨(mo)干凈并清洗光潔。

3)剝(bo)切線(xian)芯(xin)(xin)(xin)(xin)末(mo)端絕緣(yuan)。剝(bo)切線(xian)芯(xin)(xin)(xin)(xin)末(mo)端絕緣(yuan)，其長度為1/2連接管長加5mm。剝(bo)切線(xian)芯(xin)(xin)(xin)(xin)絕緣(yuan)時(shi)，不得傷及(ji)線(xian)芯(xin)(xin)(xin)(xin)導(dao)體(ti)，應順線(xian)芯(xin)(xin)(xin)(xin)絞合方向進行，以防線(xian)芯(xin)(xin)(xin)(xin)導(dao)體(ti)松散變形。

4)絕(jue)緣層端部(bu)應力處理(li)。在(zai)兩端電纜絕(jue)緣的端部(bu)做3mmX 45倒角。
