A、接线盒、开关盒及灯头盒内导线的预留长度应为 15cm。 The pre-left length of conductive wire in terminal box, switch box, and lamp-holder box should be 15cm. B、配电箱内导线的预留长度应为配电箱体周长的 1/2。 The pre-left length of conducting wire in distribution box should be 1/2 circumference of distribution box. C、出户导线的预留长度应为 1.5m。 The pre-left length of output conducting wire should be 1.5m. D、共用导线在分支处，可不剪断导线而直接穿过。 At the branch of common conducting wires, the conducting wire may not be cut off to pass through directly. （ 6）管内穿线 Threading in Pipe： 1）钢管 (电线管 )在穿线前，应首先检查各个管口的护口是否齐整，如有遗漏或破损，均应补齐更换。 Before threading the steel pipe (wire pipe), firstly check whether shields at every pipe orifice are in good order. If there is some leakage or damage, all of them should be supplemented and replaced. 2）当管路较长或转弯较多时，要在穿线的同时往管内吹入适量的滑石粉。 If the pipeline is longer or there are more swerves, inbreathe some suitable talc in the pipe while threading. 3）两人穿线时，应配合协调，一拉一送。 When threading, both personnel should coordinate harmoniously, one pulls and the other releases. （ 7）导线连接 Wire Connection： 1）单芯线并接头：导线并齐合拢。在距约 12mm 处用其中一根线芯在连接端缠绕 5-7 圈后剪断，把余头并齐折回压在缠绕线上进行涮锡处理。 Single core with parallel joint: conducting wires are combined and gathered up. At 12mm to it, use a wire core winding 57 circles at the joint and then cut off. Combine the rest and fold them at the wind wire to carry out the treatment of rinsing tin. 2）不同直径导线接头：如果是独根 (导线截面小于 2.5mm2)或多芯软线时，则应先进行涮锡处理。再将细线在粗线上距离绝缘层 15mm 处交叉，并将线端部向粗导线 (独根 )端缠绕 5-7 圈，将粗导线端折回压在细线上，最后再做涮锡处理。 Wire joints with different diameter: if a single cord (the cross section of wire is less than 2.5mm2) or a multiple cord, firstly carry out the treatment of rinsing tin. Then, cross the filament at the heavy gauge wire at 15mm away from the insulating layer, and wind the end of wire towards the end of heavy gauge wire (single) for 57 circles , fold the end of heavy 8-48 gauge wire back to press on the filament, and finally do the treatment of rinsing tin. （ 8）导线包扎 Binding up Conducting Wire： 首先用橡胶 (或粘塑料 )绝缘带从导线接头处始端的完好绝缘层开始，在包扎过程中应尽可能的收紧绝缘带。采用橡胶绝缘带包扎时，应将其拉长 2 倍后再进行缠绕。然后再用黑胶布包扎，导线接头处两端应用黑胶布封严密。 Firstly, use a rubber (or viscous plastic) insulated tape to begin from the intact insulating layer at the beginning of wire joint. In the binding process, frap the insulated tape as soon as possible. When adopting a rubber insulated tape to bind, carry out binding after drawing it more than 2 times, and then bind with a black rubberized fabric. The two ends of wire joint should be sealed closely with the black rubberized fabric. （ 9）线路检查及绝缘摇测 Line Check and Insulating Shake-measure： 1）线路检查：检查导线接、焊、包是否符合施工验收规范及质量验评标准的规定。不符合规定时应立即纠正，检查无误后再进行绝缘摇测。 Line check: Check whether the connection, weld, or wrap on conducting wire meet with the specification of construction acceptance and the regulation of quality check standard. If not meet with regulations, rectify them immediately.

When a shake-measure, separate the main line with the branch line. One is to make a shake-measure, and the other should read and record readings in time. The shake speed should be kept about 120r/min, and the reading is suitable to adopt that of 1 minute later. B、电气器具全部安装 完在送电前进行摇测，应先将线路上的开关刀闸、仪表、设备等用电开关全部置于断开位置，摇测方法同上所述，确认绝缘摇测无误后再进行送电试运行。 Carry out shake-measure before transmitting power supply after all electric appliances have been installed completely, firstly put all electric switches such as knife switches, instruments, and equipments in circuit at the position of switch off.
