The error of wire core should not be more than 1 of the equivalent diameter. The thickness of insulating layer in normal BV insulated wires should not be less than the regulations in the following table. Serial No。12345678910芯线标称截面积（mm2）Nominal cross-section area of core （mm2）1。52.546101625355070绝缘层厚度规定值(mm）Specified value of thickness on insulating layer 0。70。80。80.81.01.01。21.21。41.4（3）穿带线:穿带线也是检查管路是否畅通，管路的走向及盒、箱的位置是否符合设计及施工图的要求。 Strip： the strip is also one of requirements to check whether the pipeline is dredged as while as the direction of pipeline and the position of box accord with designs and construction drawings。 (4）清扫管路 Pipeline Cleaning:1）清扫管路的目的是清除管路中的灰尘、泥水等杂物。The aim of pipeline cleaning is to eliminate messes such as dust and sediment.2）清扫管路的方法：将布条的两端牢固地绑扎在带线上，两人来回拉动带线,将管内杂物清净。The method of pipeline cleaning is as following： bind the two ends of cloth on a strip line， two personnel pull the strip line back and forth and clean the mess in pipe. （5）放线与断线 Paying-off and Wire Breakage：1)放线：放线时导线应置于放线架或放线车上。Payingoff： When paying off, the conductive wire should be placed on paying-off supports or vehicles。 2）断线：剪断导线时，导线的预留长度应按以下四种情况考虑：Wire breakage: When cut off, the pre-left length of conductive wire should be considered according to four situations as following. A、接线盒、开关盒及灯头盒内导线的预留长度应为15cm。The preleft 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 preleft 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 preleft 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 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 Shakemeasure：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. Carry out the insulating shake-measure again after checking without any error。 2）绝缘摇测：线路的绝缘摇测一般选用500V、量程为0500M的兆欧表.Insulating shakemeasure： The insulating shakemeasure of line may select a 500V megohmmeter that the measurement range is 0500M。 3)一般线路绝缘摇测有以下两种情况：There are two situations as followings for normal line insulating shakemeasure. A、电气器具未安装前进行线路绝缘摇测时,首先将灯头盒内导线分开，开关盒内导线连通.摇测应将干线和支线分开，一人摇测,一人应及时读数并记录。摇动速度应保持在120rmin左右，读数应采用lmin后的读数为宜。When carrying out a line insulating shake-measure before not installing electric appliance， separate conducting wires in lamp holder box firstly, the conducting wires in switch box are connected. When a shakemeasure， separate the main line with the branch line。 One is to make a shakemeasure, 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 shakemeasure 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。 The method of shakemeasure is same as the above。 Carry out the test run of transmitting power supply again after confirming there is no error with insulating shake-measure。 3、桥架线槽安装 Installing Bridge and Raceway:本工程配电干线采用电缆桥架线槽明敷于吊顶、机房、配电竖井内,具体的施工流程和控制节点如下：The main line for distribution in the project adopts the cable crane span structure slot laying openly on suspended ceilings， generator rooms, or distribution shafts.
