THW hlau yog cov khoom siv hluav taws xob ntau yam uas muaj qhov zoo ntawm qhov kub thiab txias tsis kam, hnav tsis kam, muaj peev xwm siab, thiab yooj yim installation.THW hlau yog dav siv nyob rau hauv vaj tse, kev lag luam, nyiaj siv ua haujlwm, thiab cov kab hauv av, thiab nws txoj kev ntseeg siab thiab kev lag luam tau dhau los ua ib qho ntawm cov khoom siv hlau nyiam hauv kev tsim kho thiab kev lag luam hluav taws xob.
Dab tsi yog THW hlau
THW hlau yog ib hom kab hluav taws xob siv hluav taws xob uas feem ntau yog tsim los ntawm tus neeg xyuas pib ua los ntawm tooj liab lossis txhuas thiab cov khoom siv rwb thaiv tsev ua los ntawm polyvinyl chloride (PVC).THW stands rau Plastics High-temperature Weather-resistant Aerial Cable.Cov xaim no tuaj yeem siv tsis tau tsuas yog rau cov khoom siv hauv tsev, tab sis kuj rau cov kab hluav taws xob sab hauv thiab hauv av, nrog rau ntau yam kev siv.THW hlau yog dav siv nyob rau hauv North America thiab lwm cheeb tsam thiab yog nrov heev.
Features ntawm THW hlau
1.High kub tsis kam, THW xaim siv cov khoom siv PVC raws li cov txheej txheem rwb thaiv tsev, uas ua rau cov hlau muaj qhov kub thiab txias zoo heev thiab tuaj yeem tiv taus qhov kub thiab txias ua haujlwm tam sim no.Yog li ntawd, THW hlau yog tsim nyog rau siv nyob rau hauv high-temperature ib puag ncig.
2.Kev hnav tsis kam, txheej txheej ntawm THW hlau yog ua los ntawm cov khoom siv PVC, uas tuaj yeem tiv thaiv cov hlau los ntawm kev hnav thiab kev puas tsuaj.Cov hlau no tsis cuam tshuam los ntawm lwm lub cev lossis tshuaj lom neeg thiab tuaj yeem tswj tau nws qhov kev ua tau zoo rau lub sijhawm ntev.
3.High voltage muaj peev xwm, THW hlau muaj ib tug high voltage-bearing muaj peev xwm thiab yuav ua hauj lwm yam xyuam xim nyob rau hauv high voltage tej yam kev mob.Cov hlau no tuaj yeem tiv taus qhov siab tshaj plaws ntawm 600V, uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov kev siv hauv tsev thiab kev lag luam feem ntau.
4. Yooj yim rau nruab, THW hlau yog qhov hloov tau yooj yim, ua rau nws yooj yim heev rau nruab thiab xaim.Vim nws elasticity thiab yooj, THW hlau tuaj yeem khoov tau yooj yim thiab sib tw, ua kom yooj yim dua.
Kev siv THW hlau
1.Kev siv hauv tsev thiab kev lag luam, THW hlau yog lub ntsiab lus tseem ceeb ntawm cov khoom siv hluav taws xob sab hauv thiab kev faib khoom ntawm cov tsev, feem ntau yog siv rau kev siv hluav taws xob ntawm ntau yam khoom siv hauv tsev xws li teeb, qhov (socket), TV, thiab cua txias.
2.Overhead cable kab, vim THW hlau qhov kub-kub thiab hnav tsis kam, nws tuaj yeem tiv taus huab cua huab cua thiab lwm yam kev cuam tshuam, yog li nws tau siv dav hauv cov kab hluav taws xob overhead.
3.Underground cable kab, txheej rwb thaiv tsev ntawm THW hlau tuaj yeem tiv thaiv cov hlau los ntawm kev sib cuag nrog dej lossis lwm qhov chaw sab nraud, yog li nws feem ntau siv hauv cov kab hauv av.Cov hlau no tuaj yeem tiv taus cov av noo thiab qhov chaw ntub dej thiab tuaj yeem tiv thaiv cov hlau los ntawm corrosion thiab hnav.
THW wire VS.THWN kab
THW hlau, THHN hlau thiab THWN hlau yog tag nrho cov tseem ceeb ib tug tub ntxhais hlau khoom.THW cov xov hlau thiab THWN xov hlau zoo sib xws hauv cov tsos thiab cov ntaub ntawv, tab sis ib qho tseem ceeb sib txawv ntawm lawv yog qhov sib txawv ntawm cov ntaub ntawv rwb thaiv tsev thiab lub tsho.THW xov hlau siv polyvinyl chloride (PVC) rwb thaiv tsev, thaum THWN xov hlau siv qib siab thermoplastic polyethylene (XLPE) rwb thaiv tsev.Piv nrog PVC, XLPE yog superior hauv kev ua tau zoo, nrog dej zoo dua thiab kub tsis kam.Nquag, kev ua haujlwm kub ntawm THWN hlau tuaj yeem ncav cuag 90 ° C, thaum lub THW hlau tsuas yog 75 ° C, uas yog hais tias, THWN hlau muaj zog tiv taus cua sov.
THW wire VS.THHN kab
Txawm hais tias ob qho tib si THW cov xov hlau thiab THHN cov xov hlau yog tsim los ntawm cov xov hlau thiab cov txheej txheem rwb thaiv tsev, qhov sib txawv ntawm cov ntaub ntawv rwb thaiv tsev ua rau lawv qhov kev ua tau zoo sib txawv hauv qee yam.THW cov xov hlau siv cov khoom siv polyvinyl chloride (PVC), thaum THHN xov hlau siv high-temperature epoxy acrylic resin (THERMOPLASTIC HIGH HEAT RESISTANT NYLON), uas tseem nyob ruaj khov ntawm qhov kub thiab txias.Tsis tas li ntawd, THW cov xov hlau feem ntau yog softer dua THHN xov hlau kom haum rau ntau yam kev thov.
THW cov xov hlau thiab THHN cov xov hlau kuj sib txawv hauv daim ntawv pov thawj.Ob lub UL thiab CSA, ob lub koom haum kev lees paub tseem ceeb hauv Tebchaws Meskas thiab Canada, muab ntawv pov thawj rau THW thiab THHN xov hlau.Txawm li cas los xij, cov qauv ntawv pov thawj rau ob qhov sib txawv me ntsis.THW hlau yuav tsum tau ntawv pov thawj UL, thaum THHN hlau yuav tsum tau ua kom tau raws li cov cai ntawm UL thiab CSA ntawv pov thawj cov koom haum.
Raws li cov ntsiab lus, THW hlau yog cov khoom siv dav siv hlau, thiab nws txoj kev ntseeg siab thiab kev lag luam tau dhau los ua ib qho ntawm cov khoom siv hlau nyiam rau kev tsim kho thiab kev lag luam hluav taws xob.THW hlau muaj kev ua tau zoo heev thiab tuaj yeem ua tau raws li qhov xav tau ntawm ntau lub sijhawm, nqa kev yooj yim thiab kev nyab xeeb rau peb lub neej thiab kev lag luam.
