Copper vs. Aluminum Windings – A Critical Choice

Tafiti na abu da ke samun kuma yana iya zama babbarin wani abu da ke fuskantar ƙarfin transformer. Transformer mai amfani da copper wanda ke cikin oil yana da kyau a farko saboda copper yana da kyau a tsarin kariya (100% IACS vs. 61% don aluminum), yana da kyau a tsarin jiki, kuma yana da kyau a rarraba tsin gida.

Idan ana so copper windings:
