What is American Wire Gauge (AWG)?

I-American Wire Gauge (AWG) yindlela esemgangathweni yokuchaza ubungakanani bocingo eMntla Melika.Kwi-AWG, inani elikhulu, lincinci i-diameter yocingo kunye nobukhulu.Owona bungakanani bukhulu bomgangatho yi-0000 AWG, kwaye i-40 AWG yeyona sayizi incinci.Isenokubizwa ngokuba yiBrown & Sharpe yegeyiji yocingo okanye ngokulula igeyiji yocingo.

I-AWG yeye-single-strand, eqinileyo, engqukuva, intambo yombane.Yaziswa okokuqala ngo-1857 njengomgangatho wokutshintsha imilinganiselo eyahlukeneyo esetyenziswa ngabavelisi abohlukeneyo.Ukusetyenziswa kwamanani amakhulu abonisa iingcingo ezincinci kuyafana neStandard Wire Gauge, esetyenziswa eBritani.Uninzi lwamanye amazwe asebenzisa umgangatho we-metric wamazwe ngamazwe we-wire cross-section kwi-square millimeters (mm2) echazwe kwi-International Electrotechnical Commission 60228.

Ubungakanani be-AWG abubandakanyi ubungakanani be-insulation ekhusela ucingo.

I-0000 AWG ichazwa njenge-intshi ye-0.46 ububanzi, kwaye i-36 AWG ichazwa njenge-intshi ye-0.005 ububanzi.Zonke ezinye iisayizi zithathwa njengamanyathelo e-logarithmic phakathi kwezi sayizi zimbini zichaziweyo.Kukho amanyathelo angama-39 okulinganisa phakathi kwezi sayizi, kwaye umlinganiselo yi-1-to-92 ububanzi.Ngoko ke, inyathelo ngalinye le-AWG yingcambu ye-39 ye-92, okanye malunga ne-1.12293 amaxesha okutshintsha ububanzi.

Ucingo oluncinane lwegeyiji (ubukhulu) lunokuqhuba ngokukhuselekileyo umbane omninzi kunocingo olukhulu (ubukhulu obuncinane).Ukunciphisa ubukhulu be-AWG yocingo ngamathathu kuya kuphinda kabini indawo enqamlezileyo yocingo kwaye iphindwe kabini inani langoku elinokuthwala.Ukutshintsha ubukhulu be-AWG nge-10 kuya kutshintsha i-cross-section ngokuphindwe kashumi.

Ekubeni i-aluminiyam ayilunganga kumqhubi njengobhedu, ekubaleni ukuba lungakanani lwangoku ucingo lwe-aluminiyam olunokuthwala xa luthelekiswa nolwebhedu, yithathe njenge-2-gauge AWG enkulu.
