American Wire Gauge (AWG) yog txoj hauv kev los txheeb xyuas cov hlau loj hauv North America.Hauv AWG, tus lej loj dua, qhov me me ntawm txoj kab uas hla thiab thickness.Tus qauv loj tshaj plaws yog 0000 AWG, thiab 40 AWG yog tus qauv me me.Nws kuj tseem hu ua Brown & Sharpe wire gauge lossis tsuas yog qhov ntsuas ntawm cov hlau.
AWG yog rau ib leeg-strand, khoom, puag ncig, hluav taws xob conductive hlau.Nws yog thawj zaug qhia nyob rau hauv 1857 raws li tus qauv los hloov ntau yam kev ntsuas siv los ntawm cov tuam txhab sib txawv.Kev siv cov lej loj dua qhia cov xov hlau me me zoo ib yam li Standard Wire Gauge, uas yog siv hauv tebchaws Askiv.Lwm lub teb chaws feem ntau siv cov qauv ntsuas thoob ntiaj teb ntawm cov xaim hla ntu hauv square millimeters (mm2) txhais hauv International Electrotechnical Commission 60228.
AWG qhov loj me tsis suav nrog qhov loj ntawm cov rwb thaiv tsev tiv thaiv ib lub xaim.
0000 AWG txhais tau tias yog 0.46 nti inch, thiab 36 AWG txhais tau tias yog 0.005 nti inch.Tag nrho lwm qhov ntau thiab tsawg yog muab los ua cov kauj ruam logarithmic ntawm ob qhov ntau thiab tsawg.Muaj 39 ntsuas cov kauj ruam ntawm qhov ntau thiab tsawg, thiab qhov piv yog 1-rau-92 inch.Yog li ntawd, txhua kauj ruam AWG yog 39th hauv paus ntawm 92, los yog kwv yees li 1.12293 npaug ntawm qhov kev hloov ntawm txoj kab uas hla.
Ib lub ntsuas me me (qhov loj dua) xaim tuaj yeem ua kom muaj hluav taws xob ntau dua li qhov ntsuas loj dua (me me) hlau.Kev txo qis AWG qhov loj ntawm ib lub xaim los ntawm peb yuav muab ob npaug rau thaj tsam ntawm cov xaim thiab ob npaug ntawm qhov tam sim no nws tuaj yeem nqa tau.Hloov cov AWG loj los ntawm 10 yuav hloov qhov hla ntu los ntawm kaum npaug.
Txij li thaum txhuas tsis zoo li tus neeg xyuas pib zoo li tooj liab, rau kev suav cov xov hlau tam sim no muaj peev xwm nqa tau ntau npaum li cas piv rau tooj liab, xav tias nws yog 2-gauge AWG loj dua.
