Txhua yam khoom siv hluav taws xob tsis yog tsuas yog siv cov khoom siv hluav taws xob los ua cov khoom siv tam sim no, tab sis kuj siv cov ntaub ntawv insulating kom cais cov seem ntawm cov conductive, txwv kev ntws ntawm qhov tam sim no nyob rau hauv qee txoj kev, thiab tiv thaiv tus kheej kev nyab xeeb kom tsis txhob raug hluav taws xob. Yog li no, cov ntaub ntawv tsim khoom siv tawm thiab cov khoom siv insulating yog ib txwm siv ua ke nrog kev sib txuam.
Cov khoom siv tau tau zoo tshaj plaws hauv cov nyiaj, tab sis lawv tsis muaj dav vim lawv cov nqi siab. Nyiaj tau feem ntau siv rau ntawm cov neeg tiv tauj ntawm cov khoom siv hluav taws xob kom txo tau cov khoom tiv tauj ntawm cov neeg sib chwv. Tooj liab yog qhov khoom siv coj los ua feem ntau. Tooj liab muaj qhov hluav taws xob muaj qhov zoo, tab sis yog tias nws muaj qhov me me ntawm lub cev tsis zoo, nws cov conductivity yuav poob qis dua. Cov xaim tooj liab ntawm cov kab hluav taws xob thiab lub cev muaj zog yog cov hluav taws xob tooj liab ua hluav taws xob nrog cov hluav taws xob ntau, thiab cov ntsiab lus tooj liab yog 99.99%. Cov hluav taws xob hluav taws xob kev ua zoo ntawm txhuas yog zoo li tooj liab tab sis sib dua dua tooj liab. Feem ntau ntawm cov kab xa khoom tam sim no siv cov tub ntxhais steel hlau lossis cov hlau txhuas hlau hlau. Hauv lub tshuab hluav taws xob, cov khoom siv hluav taws xob thiab lwm yam kev lag luam, "tooj txhuas siv tooj liab" tau ua tiav qee yam tshwm sim.
Roj Transformer yog cov feem ntau siv ib qho ntawm cov khoom siv ua kua rwb thaiv tsev. Nws muaj cov yam ntxwv zoo rwb thaiv tsev thiab feem ntau siv los ua cov kab hluav taws xob hauv cov hloov pauv, hloov roj, thiab hloov pauv. Transformer roj yuav tsum tau dawb huv heev, thiab yog tias nws muaj qhov tsis tshua muaj dej lossis tsis huv, nws yuav txo tau nws lub rwb thaiv tsev ua tau zoo. Cov roj roj Transformer yog nquag hloov thiab ua kom sib txawv, yog li tsis txhob coj Mars mus ze rau cov cuab yeej siv roj uas hloov roj.
