Cov Khoom Siv Lub Cev ntawm Constantan

Tooj liab nickel alloy constantan hlau, uas muaj hluav taws xob tsawg resistance, zoo kub-resistant thiab corrosion-resistant, yooj yim rau kev ua thiab ua txhuas welded. Nws yog siv los ua cov khoom tseem ceeb hauv thermal overload relay, qis tsis kam thermal circuit breaker, thiab cov khoom siv hluav taws xob. Nws kuj yog ib qho khoom siv tseem ceeb rau hluav taws xob cua sov cable. Nws zoo ib yam li 's hom cupronickel.
