THHN hlau, tseem hu ua Thermoplastic High Heat-resistant Nylon-coated hlau, yog lub hauv paus ntawm cov tshuab hluav taws xob niaj hnub, muaj nuj nqis rau nws txoj kev tsim kho thiab ntau yam. Ntawm nws ntau qhov zoo, cov tshuaj tiv thaiv ntawm THHN hlau yog qhov tseem ceeb hauv nws txoj kev siv thoob plaws hauv kev lag luam. Kab lus no tshuaj xyuas cov khoom siv tshuaj tiv thaiv ntawm THHN hlau, nws qhov tsim nyog rau ib puag ncig nyuaj, thiab nws piv nrog lwm hom hlau li cas.
THHN Hlau yog dab tsi?
THHN hlau yog tsim los rau ntau yam kev siv hluav taws xob, ua tsaug rau nws cov khoom siv ruaj khov thiab ntau txheej txheej. Cov khoom tseem ceeb muaj xws li:
Copper los yog Aluminium Conductor: Lub hauv paus ntawm cov hlau uas ua hluav taws xob.
Thermoplastic rwb thaiv tsev: Muab hluav taws xob rwb thaiv tsev thiab kub tsis kam.
Nylon Txheej: Ib txheej txheej tiv thaiv uas txhim kho cov hlau tsis muaj zog thiab tshuaj lom neeg.
Qhov kev sib xyaw ua ke ntawm cov ntaub ntawv no ua rau THHN hlau, lossis xaim THHN, qhov kev xaiv nrov rau kev teeb tsa hauv thaj chaw, kev lag luam, thiab chaw tsim khoom.
Chemical Resistance ntawm THHN Hlau
Nylon Txheej raws li kev tiv thaiv Shield
Lub tsho nylon sab nrauv yog qhov tseem ceeb hauv THHN hlau cov tshuaj tiv thaiv. Nylon tiv taus ntau yam tshuaj, suav nrog:
Roj thiab roj av: Cov txheej nylon tiv thaiv kev degradation thaum raug hydrocarbons, ua THHN hlau zoo tagnrho rau cov nroj tsuag muaj thiab cov ntawv siv roj.
Acids thiab Alkalis: Nws muaj kev tiv thaiv rau cov kua qaub me me thiab cov hauv paus, kom ntseeg tau lub sijhawm ntev nyob rau hauv ib puag ncig nyuaj.
Resistance rau Environmental Chemicals
THHN xaim qhia tau tshwj xeeb hauv ib puag ncig uas nws yuav ntsib cov tshuaj xws li tshuaj ntxuav, cov kuab tshuaj, lossis cov roj nplua nyeem. Cov cuab yeej no yog qhov tseem ceeb rau kev xaim hluav taws xob hauv cov chaw tsim khoom, chaw soj nstuam, thiab lwm qhov chaw ua haujlwm.
Thermoplastic Insulation Properties
Thaum lub tsho nylon muab cov tshuaj tiv thaiv sab nraud, cov thermoplastic rwb thaiv tsev pab txhawb kev tiv thaiv ntxiv rau qee yam corrosive. Qhov kev tiv thaiv dual-txheej no ua kom cov hlau ntev ntev nyob rau hauv ib puag ncig chemically aggressive.
Kev xeem thiab kev ua raws cai
THHN hlau ua raws li cov qauv kev lag luam xws li UL 83, uas suav nrog cov kev sim rau cov roj thiab tshuaj. Kev ua raws li cov qauv no tau lees paub tias nws muaj peev xwm tiv taus cov tshuaj lom neeg feem ntau ntsib.
Cov ntawv thov hauv Chemically Demanding Environments
Cov khoom siv tshuaj tiv thaiv ntawm THHN hlau ua rau nws haum rau ntau yam kev siv:
Cov Khoom Siv Muaj: Qhov twg raug cov roj, roj, thiab tshuaj lom neeg.
Cov nroj tsuag tshuaj: Ib puag ncig nrog kev sib cuag nrog cov kua qaub, alkalis, thiab lwm yam tshuaj reactive.
Kev siv Marine: Cov hlau tiv taus degradation los ntawm cov dej ntsev thiab cov tshuaj muaj feem xyuam, ua kom muaj kev ntseeg siab hauv cov dej hiav txwv hnyav.
Kev teeb tsa hauv av: THHN hlau tsis kam rau cov tshuaj lom neeg hauv av txhim kho nws qhov tsim nyog rau kev faus conduit.
Kev sib piv nrog lwm hom hlau
THHN vs XHHW
THHN hlau: Paub txog nws qhov sib npaug ntawm cov tshuaj lom neeg thiab kub ua haujlwm vim lub tsho nylon.
XHHW kab: Muaj cov tshuaj tiv thaiv zoo tshaj plaws, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej, vim muaj kev sib txuas ntawm polyethylene rwb thaiv tsev.
THHN vs. MTW (Machine Tool Wire)
THHN hlau: Muab ntau yam kev siv nrog cov tshuaj tiv thaiv zoo dua, tshwj xeeb tshaj yog tiv thaiv cov roj.
MTW Hlau: Ntau yoog raws tab sis tsis tshua muaj zog rau qee yam tshuaj piv rau THHN.
THHN vs. TFFN (Thermoplastic Flexible Fixture Nylon)
THHN hlau: Zoo dua haum rau kev lag luam ib puag ncig vim nws cov tshuaj tiv thaiv ntau dua.
TFFN hlau: Feem ntau siv nyob rau hauv cov teeb pom kev zoo fixtures thiab muaj cov tshuaj tiv thaiv qis dua.
Cov yam ntxwv cuam tshuam rau cov tshuaj tiv thaiv
Thaum THHN hlau yog tshuaj tiv thaiv, qee yam tuaj yeem cuam tshuam nws qhov kev ua tau zoo:
Hom Tshuaj Tiv Thaiv: Ntev ntev raug rau cov tshuaj muaj zog heev lossis cov tshuaj lom neeg tuaj yeem cuam tshuam rau nws cov kav ntev.
Kub: Kev kub siab tuaj yeem ua kom muaj kev sib cuam tshuam ntawm cov tshuaj lom neeg thiab txo txoj sia ntawm cov hlau.
Mechanical Stress: Abrasion lossis txiav hauv cov nylon txheej tuaj yeem cuam tshuam cov tshuaj tiv thaiv.
Kev tu thiab kev coj ua zoo tshaj plaws
Txhawm rau kom ua tiav cov tshuaj tiv thaiv ntawm THHN hlau:
Siv Conduit Protection: Kev kaw cov xaim hauv lub raj xaim muab kev tiv thaiv ntxiv tiv thaiv cov tshuaj lom neeg.
Tsis txhob cuam tshuam ncaj qha mus ntev: Yog tias ua tau, txo qis kev sib cuag ncaj qha nrog tshuaj lom neeg.
Tshawb xyuas tsis tu ncua: Kev tshuaj xyuas niaj hnub tuaj yeem txheeb xyuas qhov kev puas tsuaj rau lub tsho nylon lossis rwb thaiv tsev, tiv thaiv kev ua tsis tiav.
