Tooj npib tsib xee alloy, uas muaj hluav taws xob tsis tshua muaj hluav taws xob, zoo tshav kub-resistant thiab corrosion-resistant, yooj yim rau kev ua tiav thiab txhuas welded. Nws yog siv los ua cov khoom tseem ceeb hauv thermal overload relay, tsis tshua muaj thermal Circuit Court breaker, thiab cov khoom siv hluav taws xob. Nws kuj yog ib yam khoom tseem ceeb rau hluav taws xob cua sov cable.
