1、铝芯多(单)股电线直线连接方法
(1)根据导线截面选择压膜和椭圆形铝套管;(2)把连接处的导线绝缘护套剥除,剥除长度应为铝
套管长度一般加上5~10mm(裸铝线无此此项),用钢丝刷去芯线表面的氧化层(膜);(3)用另一清洁的钢丝刷蘸一些凡士林锌粉膏均匀地涂抹在芯线上,以防氧化层重生。(4)用圆条形钢丝刷清除铝套管内壁的氧化层及油垢,也在管子内壁涂上凡士林锌粉膏。(5)把两根芯线相对地插入铝套管,使两个线头恰好在铝套管的正中连接。(6)根据铝套管的粗细选择适当的线模装在压
接钳上,拧紧定位螺丝后,把套有铝套管的芯线嵌入线模。(7)对准铝套管,用力捏夹钳柄,进行压接:先压两端的两个坑,再压中间的两个坑,压坑应在一直上。接头压接完毕后要检查铝套管弯曲度不应大于管长的2%,否则要用木锤校直;铝套管不应有裂纹;铝套管外面的导线不得有“灯笼”形鼓包或“抽筋”形不齐等现象。(8)擦去残余的油膏,在铝套管两端及合缝处涂刷一层快干的沥青漆。再铝套管及裸露导线部分先包两层黄蜡带,再包两层黑胶布,一直抱到绝缘层20mm的地方
