Khoom Piav Qhia
Cov xaim hluav taws xob tsis haum cov xov hlau tau siv rau cov khoom lag luam, tsheb
Qhov chaw, winding resistors, etc. Siv cov kev ua rwb thaiv tsev zoo tshaj plaws rau cov ntawv thov no, siv tag nrho cov yam ntxwv sib txawv ntawm cov txheej txheem txha hniav laus.
Tsis tas li ntawd, peb yuav nqa cov txheej txha hniav laus txheej ntawm cov khoom lag luam hlau zoo xws li nyiaj thiab platinum xaim raws li kev txiav txim. Thov siv cov txheej txheem no ua tiav.
Hom liab qab alloy hlau
Lub alloy peb tuaj yeem enamelled yog tooj liab-nickel alloy hlau, hluav taws xob hlau, manganin hlau. Kama Hlau, NICR Alloy Hlau, Fecral Alloy Hlau Thiab Hlau Hlau
