Umugozi wa emamel ukoreshwa cyane mubikoresho bya moteri na transformateur muri iki gihe. Hariho ibintu byinshi byo gusuzuma ubwiza bwinsinga. Urufunguzo ni ukureba ubudahwema bwa firime yerekana irangi, ni ukuvuga kumenya umubare wa pinholes ya firime yerekana irangi ryerekanwa munsi yuburebure. Umubare wa pinholes kuri firime irangi urashobora kwerekana cyane cyane ubwiza bwinsinga. Umubare muto wa pinholes wamenyekanye, niko ubunyangamugayo bwa firime irangi yinsinga zometseho kandi ningaruka zo gukoresha. Ibinyuranye, ubwiza bwinsinga zometseho buzagabanuka cyane. Nigute dushobora kugenzura umubare wa pinholes ya wire enameled mubikorwa?
Mubisanzwe, tuzakoresha firime ikomeye yo gusiga irangi kugirango tumenye umubare wa pinholes ya wire. Iki kizamini gikoresha cyane cyane ihame ryo gusohora umuvuduko mwinshi kugirango uhuze insinga ya electromagnetic hamwe nuruziga rwumuvuduko mwinshi unyuze mu ibahasha. Iyo uburebure bwa firime irangi bidahagije cyangwa hari inenge zikomeye zumuringa zambaye ubusa, igikoresho kizasubiza kandi cyandike umubare wihariye w inenge. Muri ubu buryo, turashobora kubona umubare wa pinholes muri iki gice cyinsinga zometseho.
Kubwibyo, mugihe tuguze insinga zometseho, dukwiye kandi kwitondera kugenzura umubare wa pinholes zinsinga zometseho, kugirango bidufashe kumenya ubwiza bwinsinga zometseho, nazo zikaba ingirakamaro cyane mugukoresha.
