将地线的焊接部位用钢锉处理，以备焊接。4.3.3 在打钢带子的同时，多股铜线排列整齐后卡在卡子里。2-3北京潞电电气设备有限公司电缆及电缆头制作安装工艺守则2903-1共10页第3页4.3.4 利用电缆本身钢带宽的二分之一做卡子，采用咬口的方法将卡子打牢，必须打两道，防止钢带松开，两道卡子的间距为15mm，见（图：2）。4.3.5 剥电缆铠甲，用钢锯在第一道卡子向上35mm处，锯一环形深痕，深度为钢带厚度的2/3，不得锯透。4.3.6 用螺丝刀在锯痕尖角处将钢带挑起，用钳子将钢带撕掉，随后将钢带锯口处用钢锉修理钢带毛刺，使其光滑。4.4 焊接地线：图:1地线采用焊锡焊接于电缆钢带上，焊接应牢固，不应有虚焊现象，应注意不要将电缆烫伤。必须焊在两层钢带上。4.5 包缠电缆，套电缆终端头套：4.5.1 剥去电缆统包绝缘层，将电缆头套下部先套入电缆。4.5.2 根据电缆头的型号尺寸，按照电缆头套长度和内径，用塑料带采用半叠法包缠电缆。塑料带包缠应紧密，形状呈枣核状（图：3）。4.5.3 将电缆头套上部套上，与下部对接、套严（图：4）。4.6 压电缆芯线接线鼻子：4.6.1 从芯线端头量出长度为线鼻子的深度，另加5mm，剥去电缆芯线绝缘，并在芯绒上涂上硅脂。4.6.2

低压侧的电缆选取应遵从客户及设计要求，但不能低于本标准。参见附表一。5 10kV电缆CJB20-630，CJBK20-630操作工艺5.1 工艺流程：遥测电缆绝缘剥电缆铠甲，打卡子焊接地线包缠电缆、套电缆终端头套压电缆芯线接线鼻子、与设备连接5.2 遥测电缆绝缘：5.2.1 选用10kV摇表，对电缆进行遥测。绝缘电阻应在2000M以上。5.2.2 电缆遥测完毕后，应将芯线分别对地放电。5.3 在整个安装过程中，请注意不要让尖锐物体划破红色硅橡胶件。5.3.1 SF6环网柜的电缆一定要固定在双通套管的正下方，不能斜扭着，斜扭的电缆会对套管产生扭曲力，长时间的扭曲力会破坏套管和柜体的密封，使SF6开关漏气。会使套管产生裂纹，导致高压短路、爆炸。5.3.2 锯掉电缆（有水的）端头：按照安装长度的需要，剥离长度350mm- 800mm的电缆外护套。清除填料留出内护套、锉光钢带铠装。用PVC带临时包绕铜屏蔽带端部，将三相电缆稍加整形。把外护套向下打磨150mm长，清洗干净。（图：5）5.3.3 用铜扎线绑扎铜编织带（地线）；用锡把钢铠，铜屏蔽层；铜扎线，铜编织带（地线）焊牢；清理掉焊锡及扎线部的尖头，用PVC带稍加包绕，套上分支套，均匀加热收缩；然后套上热缩管，均匀加热收缩；根据安装长度需求，将三叉部初步固定，等全部完工后再正式固定。2-5北京潞电电气设备有限公司电缆及电缆头制作安装工艺守则2903-1共10页第5页（图：5）。5.4 见（图：6）5.4.1 比照各相的母线套管中心，往下50 mm -55 mm锯齐电缆，或者把螺杆和端子（线耳）先挂住，再比照电缆长度锯齐。5.4.2 各相电缆的长度应尽量适合安装，过长或过短，都会使电缆端子平面和母线套管接触不良。接触不良在有负荷电流时，会发热升温、过热高温会端子发红，会使电缆着火燃烧。5.4.3 剥离总长170 mm -175 mm的热缩管：留出铜屏蔽20 mm、半导电层20 mm、保证芯绝缘85 mm-90没m，露出线芯45mm。5.4.4 半导电切断处要保证圆滑过度，不能有尖角或翘起。芯绝缘应光滑、无凹痕、清洁。2-6北京潞电电气设备有限公司电缆及电缆头制作安装工艺守则2903-1共10页第6页5.4.5 在芯绝缘端部倒145O斜角，用PVC带包绕线芯。5.5 在铜屏蔽带上方约2mm处，用半导电带包绕台阶，台阶宽20mm -25mm，厚度5mm，即直径比电缆芯绝缘远大10mm。特别注意：所有硅橡胶件套入时必须在对应接触部位分别抹上硅脂。见（图：7）5.6 用清洁纸从上往下，清洁电缆芯绝缘；等稍干一会，在标A和虚线的部位，即芯绝缘表面和应力体的小内孔中均匀抹上硅脂。注意：尽量不要涂在半导电层上。见（图：8）5.7 见（图：9）。5.7.1 往电缆芯绝缘上边转动边推入应力体，直到半导电带台阶抵紧应力体内部的凸缘为止。5.7.2 紧靠应力体下沿用PVC带包绕多层，作为检查应力体定位的标记，后边安装时要检查应力体是否移动。5.7.3 去掉线芯端部的PVC带，套上合适的端子，准备压接。5.7.4 电缆端子（线耳）压接时，一定要注意端子平面的方向。它要和母线套管的铜平面平行贴合，才能保证导电接触良好。接触不良在有负荷电流时，会发热升温、过热高温会使端子发红，会使电缆着火燃烧。5.8 与设备连接5.8.1 往双通套管上紧固M16/1275（M12/1260）的双头螺杆，M16向前。5.8.2 往CJB-外套下边孔的内壁和应力体上部，均匀涂抹硅脂。5.8.3 对准端子的方向，用力把装好应力体的电缆一次性推入CJB-外套内。注意：应力体没有沿电缆向下移动、PVC定位标记应当在原位，没有移动。应力体下部露出30mm50mm左右。2-7北京潞电电气设备有限公司电缆及电缆头制作安装工艺守则2903-1共10页第7页5.9

Four are standard visits, except as required to participate in training, no other activity. Five is to improve news reporting, for propaganda work strictly according to the regulations. Six is strictly your presentation published strictly according to the regulations. Seven is strictly thrift, required the use of vehicles and office space and corporate hospitality. 3, change the style. Propaganda and ideological work of the new situation and new requirements of the new tasks, had done a lot of fruitful work, has made many achievements, but further closer to the grass roots, close to reality, close to the masses and also inadequate innovation must continue to improve. Second, the four winds some outstanding issues 1, oppose formalism. One theory is that he didnt, with less close contact. Theoretical study of consciousness is not high enough, system performance is not strong enough; more passive learning, active learning few generalities and learn more, delving into less. Especially based on rational thinking on major issues, applying theory to guide the work done is not good enough, not really understand and grasp the spirit and essence of the scientific Outlook on development, did not truly achieve mastery, to apply, to a certain extent, affect the development and implementation of ideas and initiatives. Second, work arrangements, and less supervision. Propaganda and ideological work is the objective, which needs to keep the continuity efforts deployed, but stressed in the work time, less supervision. For example, color weekends in the summer theatrical activities, city square performances, urging townships, communities and rural areas shows the implementation is inadequate, insufficient cultural an educational role to play. Third base enough, master grass-less real. Propaganda and ideological work in the new situation of characteristics and regularity of enough, deep enough for grass-roots public opinion Dynamics survey, for grass-roots typically drive less. For example, rural culture team active, . Im not actively take the initiative to take up, the lack of spirit of daring to, resulting in some job had a lot of power, but no tangible results. Third, innovation, lack of motivation. Emancipation did not end, innovation does not exist. In practical work, not your head, previous work experience, lack of innovation initiatives, study on the characteristics of propaganda and ideological work under the new situation through, grip on grassroots ideological trends and changes are not deep, to promote new initiatives and explore new methods of ideological and cultural work is not much, and some lack of relevance and timeliness. 4, discipline, lowering, and hard work are lacking. While working and enterprising spirit down. No real solution to treat yourself right, correctly treat past honors, their complacency, and work to see their scores more, less checking his own shortcomings, like to listen to the praise, satisfied face, online promotion, there are typical, and lack of high standards and strict requirements, the effect is real.
