THHN thiab XHHW yog ob hom kab hluav taws xob uas feem ntau siv hauv kev teeb tsa hluav taws xob. Txawm hais tias lawv yuav zoo sib xws, muaj qee qhov sib txawv ntawm ob.
THHN hlau stands rau Thermoplastic High Heat-resistant Nylon coated hlau. Nws yog ib hom hlau uas tsim los ntawm tooj liab conductors, uas yog coated nrog PVC rwb thaiv tsev. THHN xov hlau raug ntsuas txog li 90 degrees Celsius (194 degrees Fahrenheit) thiab feem ntau siv rau hauv qhov chaw qhuav.
XHHW hlau stands rau Cross-Linked High Heat-resistant Water-resistant hlau. Cov hlau no yog tsim los ntawm cov khoom siv thermal rwb thaiv tsev uas muaj peev xwm tiv taus qhov kub thiab txias (txog 90 degrees Celsius) thiab dej-resistant. XHHW xov hlau feem ntau yog siv nyob rau hauv ob qho tib si qhuav thiab ntub qhov chaw, nrog rau kev teeb tsa hauv av.
Hais txog kev hloov pauv, THHN hlau yog hloov tau ntau dua li XHHW hlau vim nws cov rwb thaiv tsev PVC. Txawm li cas los xij, XHHW hlau yog qhov ruaj khov dua thiab muaj lub neej ntev dua vim nws cov thermoset rwb thaiv tsev.
Thaum kawg, kev xaiv ntawm THHN thiab XHHW hlau yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov xwm txheej uas yuav siv tau. Ob lub xov hlau yog tsim nyog rau feem ntau cov khoom siv hluav taws xob thiab feem ntau siv hauv thaj chaw, kev lag luam, thiab chaw tsim khoom.
