Nyob rau hauv lub ntiaj teb no ntawm hluav taws xob thaiv, nws yog ib qho tseem ceeb uas yuav tsum tau siv txoj cai ntawm cov hlau los xyuas kom meej kev ruaj ntseg, efficiency, thiab durability. Ib qho ntawm feem ntau siv hom hlau hauv ob qho tib si hauv tsev thiab kev lag luam yog THHN hlau (Thermoplastic High Heat-resistant Nylon-coated). Hom xov hlau no muaj ntau yam thiab haum rau ntau yam kev siv hluav taws xob. Hauv tsab xov xwm no, peb yuav tshawb xyuas seb THHN cable yog dab tsi, nws cov yam ntxwv tseem ceeb, kev siv, thiab cov ntsiab lus tseem ceeb thaum siv hom xov hlau no hauv ntau qhov kev teeb tsa hluav taws xob.
THHN Cable yog dab tsi?
THHN cable yog hais txog ib hom hluav taws xob tshwj xeeb uas siv rau hauv ntau hom kev lag luam, kev lag luam, thiab cov xaim hluav taws xob hauv tsev. Lub sij hawm THHN stands rau Thermoplastic High Heat-resistant Nylon-coated, uas piav qhia txog cov xaim rwb thaiv tsev thiab nws muaj peev xwm tiv taus qhov kub thiab txias. THHN hlau feem ntau yog siv rau cov ntawv thov tsis nyob hauv tsev, tshwj xeeb tshaj yog nyob rau hauv cov kav dej thiab ua ib feem ntawm cov khoom siv hluav taws xob.
THHN hlau yog tsim los ntawm ob peb yam tseem ceeb, txhua tus pab txhawb rau nws cov durability, yooj, thiab kev nyab xeeb nta. Cov khoom tseem ceeb ntawm THHN hlau feem ntau yog tooj liab (txawm hais tias txhuas kuj tuaj yeem siv rau qhov loj dua), thiab nws yog coated nrog ib txheej tshwj xeeb thermoplastic rwb thaiv tsev uas tiv taus cua sov, noo noo, thiab puas.
Cov yam ntxwv tseem ceeb ntawm THHN Cable:
Cov khoom siv rwb thaiv tsev: Cov hlau yog insulated nrog cov khoom siv thermoplastic (feem ntau yog PVC), uas muab hluav taws xob rwb thaiv tsev. Qhov rwb thaiv tsev no yog tsim los tiv thaiv cov hlau thiab tiv thaiv hluav taws xob luv.
Txheej: Cov txheej txheej txheej ntawm THHN hlau feem ntau yog ua los ntawm nylon, uas ua rau nws muaj zog ua kom zoo dua thiab ua kom muaj zog. Cov nylon txheej no pab cov hlau tuav nws cov kav ntev hauv ib puag ncig uas lub cev hnav thiab tsim kua muag yuav ua rau muaj kev puas tsuaj.
Kev ntsuas hluav taws xob: THHN hlau muaj qhov ntsuas hluav taws xob ntawm 600 volts, uas txhais tau tias nws tuaj yeem siv rau hauv cov tshuab hluav taws xob feem ntau rau kev xa hluav taws xob.
Kev ntsuas kub: THHN hlau yog ntsuas rau qhov kub ntawm 90 degree (194 degree F) nyob rau hauv ib puag ncig qhuav thiab 75 degree (167 degree F) nyob rau hauv qhov chaw ntub dej. Qhov kev tiv thaiv kub kub no tso cai rau nws siv rau ntau qhov chaw xav tau, suav nrog cov kub kub.
Cov khoom siv coj ua: Tus neeg xyuas pib ntawm THHN hlau feem ntau yog ua los ntawm tooj liab, uas yog cov khoom siv zoo heev. Tooj liab yog dav nyiam vim nws cov hluav taws xob zoo heev, uas tso cai rau THHN hlau ua haujlwm tau zoo.
Lub cev muaj zog: THHN hlau yog paub txog nws qhov yooj, ua kom yooj yim rau nruab rau hauv qhov chaw nruj, cov kav dej, thiab lwm qhov chaw txwv. Nws kuj yog resistant rau abrasion, ya raws, thiab ib co tshuaj, ua rau nws haum rau industrial daim ntaub ntawv.
Cov yam ntxwv tseem ceeb ntawm THHN Cable
1. Thaum tshav kub kub tsis kam
Ib qho ntawm cov yam ntxwv ntawm THHN hlau yog nws cov cua kub tsis kam. Cov rwb thaiv tsev thermoplastic tshwj xeeb yog tsim los tiv thaiv kub txog 90 degree (194 degree F) nyob rau hauv qhuav qhuav thiab 75 degree (167 degree F) nyob rau hauv ntub dej. Qhov no ua rau nws tsim nyog rau kev siv ntau qhov chaw kub kub, xws li cov chaw tsim khoom, hluav taws xob vaj huam sib luag, thiab thaj chaw uas cov tshuab tsim hluav taws xob tseem ceeb.

Cov txheej nylon txheej ntawm THHN hlau muaj kev tiv thaiv zoo tshaj plaws tiv thaiv lub cev thiab tsim kua muag. Kev puas tsuaj ua kom ntseeg tau tias cov hlau tuaj yeem tiv thaiv qhov chaw ntxhib, lwm yam xov hlau, lossis cov khoom tsis muaj kev puas tsuaj rau lub rwb thaiv tsev. Qhov no ua rau THHN hlau zoo tagnrho rau kev teeb tsa qhov twg cov hlau yuav raug cuam tshuam rau cov neeg kho tshuab kev ntxhov siab, xws li hauv cov khoom siv hluav taws xob lossis cov kav dej.
3. Moisture Resistance
Txawm hais tias THHN hlau feem ntau yog tsim los rau qhov chaw qhuav, cov nylon txheej kuj muab qee qhov kev tiv thaiv noo noo. Qhov no ua rau cov xaim haum rau siv nyob rau hauv ib puag ncig uas tej zaum yuav muaj qee zaus raug cov av los yog dej. Txawm li cas los xij, rau kev teeb tsa hauv qhov chaw ntub dej, nws raug nquahu kom siv THWN (Thermoplastic Thaum tshav kub kub thiab Dej-resistant Nylon-coated) xaim, uas muaj cov dej tsis zoo.
4. Yooj yim
THHN hlau yog lub npe hu rau nws yooj, uas yog ib qho ntawm nws qhov tseem ceeb zoo. Cov hlau tuaj yeem khoov tau yooj yim thiab xa mus los ntawm qhov chaw nruj, ua rau nws zoo tagnrho rau kev teeb tsa uas tsis muaj chaw ua haujlwm. Qhov kev hloov pauv no tseem tso cai rau kev txhim kho yooj yim dua, txo qhov kev pheej hmoo ntawm cov xaim puas thaum tuav thiab teeb tsa.
5. Hluav taws xob conductivity
Tus neeg xyuas pib tooj liab hauv THHN xaim muab cov khoom siv hluav taws xob zoo heev, ua kom muaj kev tiv thaiv tsawg heev rau cov hluav taws xob ntws. Copper yog tus neeg xyuas pib siv ntau tshaj plaws hauv kev xaim hluav taws xob vim nws cov conductivity zoo dua piv rau lwm cov hlau xws li txhuas. Lub siab conductivity ntawm THHN xaim tso cai rau nws xa hluav taws xob hluav taws xob zoo, ua rau nws tsim nyog rau ntau yam kev siv hluav taws xob.
6. Tshuaj tiv thaiv
Ntxiv nrog rau nws qhov kev tiv thaiv corrosion, THHN hlau kuj tseem tiv taus ntau yam tshuaj, suav nrog roj, kuab tshuaj, thiab cov kua qaub. Cov yam ntxwv no ua rau nws tsim nyog rau kev siv nyob rau hauv ib puag ncig uas muaj cov tshuaj lom neeg, xws li hauv cov chaw tsim khoom, chaw kuaj mob, thiab lwm qhov chaw lag luam.
7. Voltage thiab tam sim no muaj peev xwm
THHN hlau yog tsim los tswj 600 volts, uas yog txaus rau feem ntau cov khoom siv hluav taws xob. Nws tuaj yeem siv rau ntau lub hom phiaj, suav nrog cov khoom siv hluav taws xob, khoom siv, thiab tshuab hauv kev lag luam thiab chaw nyob. Cov hlau tseem tuaj yeem nqa tau qhov tseem ceeb tam sim no, nyob ntawm nws qhov ntsuas, uas txhais tau hais tias nws tuaj yeem tswj tau cov kev xav tau ntawm ntau lub tshuab.
Kev siv ntawm THHN Cable
THHN hlau yog ntau yam thiab dav siv hlau hom hauv ntau yam khoom siv hluav taws xob. Qee qhov ntawm nws cov kev siv feem ntau suav nrog:
