Kodi American Wire Gauge (AWG) ndi chiyani?

American Wire Gauge (AWG) ndiye njira yodziwika bwino yowonetsera kukula kwa waya ku North America.Mu AWG, chiwerengero chokulirapo, chocheperako ndi mainchesi a waya.Kukula kwakukulu kwambiri ndi 0000 AWG, ndipo 40 AWG ndiye kukula kochepa kwambiri.Itha kutchedwanso Brown & Sharpe wire gauge kapena kungoyezera waya.

AWG ndi waya wa chingwe chimodzi, cholimba, chozungulira, choyendera magetsi.Idayambitsidwa koyamba mu 1857 ngati muyezo wosinthira miyeso yosiyanasiyana yogwiritsidwa ntchito ndi opanga osiyanasiyana.Kugwiritsa ntchito manambala akulu osonyeza mawaya ang'onoang'ono ndikofanana ndi Standard Wire Gauge, yomwe imagwiritsidwa ntchito ku Britain.Mayiko ena ambiri amagwiritsa ntchito mulingo wapadziko lonse lapansi wa waya wodutsa magawo masikweya mamilimita (mm2) wofotokozedwa mu International Electrotechnical Commission 60228.

Kukula kwa AWG sikuphatikiza kukula kwa zotchingira zoteteza waya.

0000 AWG imatanthauzidwa ngati mainchesi 0.46 m'mimba mwake, ndipo 36 AWG imatanthauzidwa ngati mainchesi 0.005 m'mimba mwake.Makulidwe ena onse amatengedwa ngati masitepe a logarithmic pakati pa makulidwe awiriwa.Pali masitepe 39 pakati pa kukula kwake, ndipo chiŵerengero chake ndi 1 mpaka 92 m'mimba mwake.Choncho, sitepe iliyonse ya AWG ndi 39th root of 92, kapena pafupifupi 1.12293 nthawi kusintha kwake.

Waya wocheperako (yokulirapo) imatha kuyendetsa magetsi ochulukirapo kuposa waya wokulirapo (yocheperako).Kuchepetsa kukula kwa waya wa AWG ndi atatu kudzawirikiza kawiri gawo la waya ndikuwirikiza kawiri kuchuluka kwa mawaya omwe anganyamule.Kusintha kukula kwa AWG ndi 10 kudzasintha magawo khumi.

Popeza aluminiyamu siwofanana ndi kondakitala ngati mkuwa, powerengera kuchuluka kwa waya wa aluminiyamu wamakono kuyerekeza ndi mkuwa, ganizirani ngati 2-gauge AWG yokulirapo.
