Mombamomba ny vokatra
Ireo tariby fanoherana enameled ireo dia nampiasaina betsaka ho an'ny resistors mahazatra, fiara
ny ampahany, miolikolika resistors, sns mampiasa ny insulation fanodinana mety indrindra ho an'ireo fampiharana ireo, manararaotra tanteraka ny mampiavaka ny enamel coating.
Ho fanampin'izay, hanao insulation coating enamel amin'ny tariby metaly sarobidy toy ny tariby volafotsy sy platinum izahay rehefa misy baiko. Azafady, ampiasao ity famokarana ity amin'ny baiko.
