What is American Wire Gauge (AWG)?

Ko te Waea Waea Amerika (AWG) te huarahi paerewa hei tohu i te rahi waea i Amerika Te Tai Tokerau.I roto i te AWG, ka nui ake te nama, ka iti ake te diameter waea me te matotoru.Ko te rahi paerewa nui rawa atu ko te 0000 AWG, ko te 40 AWG te iti rawa o te rahi o te paerewa.Ka kiia pea ko Brown & Sharpe te ine waea, ko te ine noa ranei o te waea.

Ko te AWG mo te whenu kotahi, totoka, porowhita, waea kawe hiko.I whakauruhia tuatahitia i te tau 1857 hei paerewa hei whakakapi i nga momo inenga e whakamahia ana e nga kaihanga rereke.Ko te whakamahi i nga tau nui e tohu ana i nga waea iti he rite ki te Waea Waea Paerewa, e whakamahia ana i Peretana.Ko te nuinga o etahi atu whenua e whakamahi ana i te paerewa inenga o te ao mo te wahanga waea i roto i te tapawha mitamano (mm2) kua tautuhia i roto i te International Electrotechnical Commission 60228.

Ko te rahi o te AWG kaore e uru ki te rahi o te whakamarumaru e tiaki ana i te waea.

Ko te 0000 AWG he 0.46 inihi te whanui, a ko te 36 AWG he 0.005 inihi te whanui.Ko etahi atu rahinga katoa ka ahu mai hei hikoi taurau i waenga i enei rahinga e rua kua tautuhia.E 39 nga kaupae ine i waenganui i enei rahi, a ko te 1-ki-92 te whanui te owehenga.No reira, ko ia taahiraa AWG ko te 39th pakiaka o te 92, he 1.12293 pea te huringa o te diameter.

Ma te waea ine iti (rahi ake) ka taea te kawe i te hiko nui atu i te waea ine nui (te rahi iti).Ko te whakaiti i te rahi o te AWG o te waea ma te toru ka whakawharuatia te horahanga whiti o te waea, ka ruarua te nui o te iao ka taea e ia te kawe.Ko te whakarereke i te rahi o te AWG ma te 10 ka huri i te waahanga whakawhiti ma te tekau nga wa.

I te mea kaore te konumohe i rite ki te pai o te kaikawe i te parahi, mo te tatau i te nui o te waa ka taea e te waea konumohe te kawe ki te waea parahi, whakaarohia he AWG 2-mehua nui ake.
