Cov Khoom Siv Lub Cev Constantan

Tooj liab Nickel Alloy Constantan hlau, uas muaj qhov hluav taws xob hluav taws xob tsawg, ua kom sov kom muaj zog thiab corrosion-resistant thiab corrosion-resistant thiab ua kom tiav thiab coj welded. Nws yog siv los ua cov khoom tseem ceeb hauv lub thermal sib tshooj relay, tsis tshua muaj cua sov circuit breaker breaker, thiab cov khoom siv hluav taws xob. Nws tseem yog ib qho khoom tseem ceeb rau hluav taws xob cua sov cable. Nws zoo sib xws li 's hom cuponickel.
