Quid est American Wire Gauge (AWG)?

American Wire Gauge (AWG) est norma via ad significandum magnitudinem filum in America Septentrionali.In AWG maior numerus, minor filum diametri et crassitudinis.Maxima magnitudo mensurae 0000 AWG est, et 40 AWG mensura minima est.Dici potest etiam Brown & Sharpe filum METIOR vel simpliciter METIOR filum.

AWG filum electrically rotundum solum, solidum, rotundum est.Primum anno 1857 inductum est ut vexillum ad varias mensuras a diversis fabricantibus adhibitas reponeret.Usus numerorum majorum pro minoribus filis est similis Latin Wire Cange, quod in Britannia adhibetur.Plurimae aliae nationes utuntur norma metrica internationali filum crucis-sectionis in millimetris quadratis (mm2) definitis in Commissione Electrotechnica Internationali 60228.

AWG amplitudo amplitudinem filum protegens insulationis non includit.

0000 AWG definitur diametro 0,46 pollices, & 36 AWG definitur 0.005 digitorum diametro.Omnes aliae magnitudines sumuntur ut gradus logarithmi inter has duas magnitudinum definitarum.Gradus inter has magnitudinum sunt 39 coniecturae, et proportio diametri ad 92.Uterque igitur gradus AWG est radix 39 92, vel circiter 1,12293 temporum mutatio diametri.

Minor METIOR (maior amplitudo) filum plus electricitatis tuto ducere potest quam maiorem METIOR (minor amplitudo) filum.Diminuens AWG magnitudinem fili tribus in ambitum sectionis transversim duplicabit filum et dupla currentis quantitatem ferre potest.Mutans AWG magnitudinem per 10 mutabit crucem sectionem per decuplum.

Cum aluminium conductoris non tam bonum quam aeris, ad calculandum quantum filum aluminium currenti comparari potest cum uno aeneo, considera ut 2-METB AWG maius.
