Cov tooj liab-raws li tsis tshua muaj hluav taws xob cua sov alloy yog dav siv nyob rau hauv low-voltage circuit breaker, thermal overload relay, thiab lwm yam.
low-voltage hluav taws xob khoom. Nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob tsawg. Cov ntaub ntawv tsim
los ntawm peb lub tuam txhab muaj cov yam ntxwv ntawm kev ua haujlwm zoo sib xws thiab kev ruaj ntseg zoo dua. Peb tuaj yeem muab txhua yam
round hlau, tiaj tus thiab cov ntaub ntawv.

khoom siv hluav taws xob. Nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob tsawg. Cov ntaub ntawv tsim los ntawm peb lub tuam txhab
muaj cov yam ntxwv ntawm kev ua haujlwm zoo sib xws thiab superior stability. Peb tuaj yeem muab txhua yam ntawm cov hlau puag ncig, tiaj tus thiab
cov ntaub ntawv.
Lub alloy yog non-magnetic. Nws yog siv rau hluav taws xob regenerator qhov sib txawv ntawm cov resistor thiab cov strain resistor,
potentiometers, cua sov xov hlau, cua sov cables thiab mats. Ribbons yog siv rau cua sov ntawm bimetals. Lwm daim ntawv thov
yog kev tsim cov thermocouples vim tias nws tsim lub zog hluav taws xob siab (EMF) hauv kev koom nrog lwm cov hlau.
