电线是大家在生活中***常使用和关注的，更是电力检修中不可或缺的一部分，但是关于每个电线颜色都代表什么意思，你知道吗?今天一起来了解一下吧！电线是什么？万州电线电缆YJV现货，重庆电线电缆厂电线是指传输电能的导线。分裸线、电磁线和绝缘线。裸线没有绝缘层，包括铜、铝平线、架空绞线以及各种型材(如型线、母线、铜排、铝排等)。它主要用于户外架空及室内汇流排和开关箱。电磁线是通电后产生磁场或在磁场中感应产生电流的绝缘导线。它主要用于电动机和变压器绕圈以及其他有关电磁设备。其导体主要是铜线，应有薄的绝缘层和良好的电气机械性能，以及耐热、防潮、耐溶剂等性能。选用不同的绝缘材料可获得不同的特性。1.黑色装置和设备的内部布线。2.棕色直流电路的正极。3.红色三相电路和C相;半导体三极管的集电极;半导体二极管、整流二极管或可控硅管的阴极。4.***三相电路的A相;半导体三极管的基极;可控硅管和双向可控硅管的控制极。5.绿色三相电路的B相。6.蓝色直流电路的负极;半导体三极管的发射极;半导体二极管、整流二极管或可控硅管的阳极。7.淡蓝色三相电路的零线或中性线;直流电路的接地中线。8.白色双向可控硅管的主电极;无指定用色的半导体电路。9.黄和绿双色(每种色宽约15～100毫米交替贴接)安全用的接地线。10.红、黑色并行万州电线电缆YJV现货，重庆电线电缆厂用双芯导线或双根绞线连接的交流电路。1.三相交流电路A相：***B相：绿色C相：红色零线或中性线：蓝色保护接地线：黄绿双色。2.单相电路中火线：红色零线：蓝色3.用双芯导线或双根绞线连接的交流电路：红黑色并行4.直流电路：正极：棕色负极：蓝色接地线：蓝色。5.整个装置及设备的内部布线一般推荐：黑色。软线和硬线的优缺点比较从电线表象来看万州电线电缆YJV现货，重庆电线电缆厂软线又称护套线，一般是由多股直径在1mm以下的多股铜丝缠绕在一起的导线。硬线则是一根比较粗的单股金属导线，一般直接在1mm以上。从电线的本质来看软线的线丝比较细而柔软，方便转弯穿管。但是时间久了容易老化，影响整个电路的使用寿命。硬线本质上截面比较比较小，耐短路电流的冲击，且硬线不容易氧化，寿命相对比软线长一些。但是硬线本身计较坚硬，不好做转弯穿管处理。家装时软线好用还是硬线寿命更长?软线的每根铜丝都比较细，在安装过程中容易损伤断裂，从而影响电线的导电能力。相反硬线则不会受施工过程的影响，在可靠性和耐用性上都要好的多。万州电线电缆YJV现货，重庆电线电缆厂Wireisthemostcommonlyusedandconcernedinourlives,anditisanindispensablepartofthepoweroverhaul,butaboutwhateachcolorofthewiremeans,youknow?Let'sgettoknowtoday.Whatistheelectricwire?WanzhouwireandcableYJVspot,ChongqingwireandcablefactoryWiresrefertoconductorsthattran***itelectricenergy.Itisdividedintobarewires,electromagneticwiresandinsulatedwires.Barewirewithoutinsulation,includingcopper,aluminumflatwire,overheadstrandedwireandavarietyofprofiles(suchasprofiles,busbar,copperrow,aluminumrow,etc.).Itismainlyusedforoutdooroverheadandindoorbusbarsandswitchgearboxes.Theelectromagneticwireisaninsulatedconductorwhichgeneratesmagneticfieldafterelectrifiedorinducescurrentinamagneticfield.Itismainlyusedformotorandtransformercirclingandotherrelatedelectromagneticequipment.Itsconductorismainlycopperwire,shouldh***eathininsulatinglayerandgoodelectricalandmechanicalproperties,aswellasheatresistance,moistureresistance,solventresistanceandotherproperties.Differentinsulationmaterialscanbeusedtoobtaindifferentcharacteristics.1.blackInternalwiringofdevicesandequipment.2.BrownThepositivepoleoftheDCcircuit.3.redThreephasecircuitandCphase;Collectorofsemiconductortriode;Thecathodeofsemiconductordiode,rectifierdiodeorthyristor.4.yellowAphaseofthree-phasecircuit;Thebaseofsemiconductortriode;Thecontrolpoleofthyristorandbidirectionalthyristor.5.greenTheBphaseofthreephasecircuit.6.blueThenegativepoleofDCcircuit;Emitterofsemiconductortriode;Theanodeofsemiconductordiode,rectifierdiodeorthyristor.7.lightblueThezerolineorneutrallineofathree-phasecircuit;ThegroundinglineofDCcircuit.8.whiteThemainelectrodeofbidirectionalthyristor.Nosemiconductorcircuitwithspecifiedcolor.9.yellowandgreenbicolor(eachwithawidthofabout15~100mmalternatelyattached).Securegroundingwire.10.redandblackparallelWanzhouwireandcableYJVspot,ChongqingwireandcablefactoryAnalternatingcurrentcircuitconnectedbytwocoreconductorsortwotwistedwires.1.three-phasealternatingcurrentcircuitAphase:yellowBphase:GreenCphase:RedZerolineorneutralline:blue.Protectionofgroundingwire:yellowgreendoublecolor.2.singlephasecircuitFireline:RedZeroline:Blue3.ACcircuitsconnectedwithtwocorewiresortwostrands:redandblackparallel4.DCcircuit:Cathode:BrownNegativepole:BlueGroundingwire:blue.5.theinternalwiringofthewholedeviceandequipmentisgenerallyrecommended:black.ComparisonofadvantagesanddisadvantagesbetweensoftwireandhardwireWanzhouwireandcableYJVspot,Chongqingwireandcablefactory.Softwires,alsoknownassheathwires,areusuallywireswoundtogetherbymultiplestrandsofcopperwirelessthan1mmindiameter.Hardwireisarelativelythicksinglestrandmetalconductor,usuallymorethan1mmdirectly.FromthenatureofwiresThewireofsoftwireisthinandsoft,easytoturnandwear.Butlongtimeiseasytoaging,whichaffectstheservicelifeofthewholecircuit.Hardwiresareessentially***allerincross-section,resistanttoshort-circuitcurrentimpact,andhardwiresarenoteasytooxidation,lifeisrelativelylongerthansoftwires.Butthehardlineitselfishard,anditisdifficulttohandletheturningpipe.Doyouwanttouseflexiblecordorhardwireforlongerlife?Eachcopperwireofthesoftwireisrelativelyfine,anditiseasytodamageandbreakduringinstallation,thusaffectingtheconductivityofthewire.Onthecontrary,thehardlinewillnotbeaffectedbythec***tructionprocess,anditwillbemuchbetterinreliabilityanddurability.WanzhouwireandcableYJVspot,Chongqingwireandcablefactory)
