Saizi yewaya inoreva kuyerwa kwedhayamita yewaya. Ichi chinhu chakakosha chekufunga nezvacho pakusarudza waya yakakodzera kushandiswa kwayo. Saizi yewaya inowanzomiririrwa nenhamba. Nhamba diki, dhayamita yewaya yakakura. Nhamba yakakura, dhayamita yewaya idiki. Kuti unzwisise zviyero zvewaya zvakarongwa, zvakakosha kuti uve nekunzwisisa kwekutanga kwehurongwa hwewaya.
Sisitimu ye wire gauge inzira yakajairika yekuyera dhayamita yewaya uye inowanzoshandiswa muUnited States. Wire gauge size standard inonyanya kushandiswa ndiyo American Wire Gauge (AWG) system. MuAWG systems, wire gauge sizes dzinotangira pa0000 (4/0) kusvika pa40, apo 0000 ndiyo dhayamita yepamusoro yewaya uye 40 ndiyo dhayamita shoma yewaya.
Tafura 1: chati yegeji yewaya
Munyaya yemetrology, kureva, chidzidzo chesainzi chekuyera, mageji ewaya anoshandiswa kuyera dhayamita kana nzvimbo yakachinjika yewaya dzakatenderera, dzakasimba, dzisina feri, dzinofambisa magetsi. Nekushandisa dhayamita kana nzvimbo yakachinjika yewaya, mageji ewaya anobatsira vashandisi kuziva kugona kwewaya dzinofambisa magetsi.
Saizi dzewaya dzinoratidza kuti ingani magetsi anogona kupfuudzwa kana kupfuudzwa newaya zvakachengeteka, asiwo resistance yewaya pamwe nehuremu hwayo pahurefu hwese. Gauge yewaya inoratidzawo ukobvu hweconductor iyo maerekitironi anoyerera nepakati payo. Kuti ipfuure zvakanaka, conductor yewaya inofanira kuwedzerwa kuitira kuderedza resistance.
Kunzwisisa saizi dzewaya dzemagetsi dzakatevedzana kwakakosha pakushandisa kwakasiyana-siyana kwakadai sewaya dzemagetsi, waya dzemotokari, nezvimwewo. Kusarudza saizi chaiyo yewaya dzemagetsi kwakakosha pakuona kuti waya inogona kutakura simba remagetsi rinodiwa zvakachengeteka pasina kupisa zvakanyanya kana kukonzera kudzikira kwemagetsi.
