Ib, Dab tsi yog qhov vuam cable?
Vuam cables, feem ntau hu ua welding torch cables, raug xa mus rau siab -lub zog roj hmab- sheathed vuam tshuab cables. Lawv yog hom YC dav dav- lub hom phiaj roj hmab- sheathed cable, feem ntau yog siv rau theem nrab- sab txuas ntawm vuam tshuab thiab rau kev sib txuas vuam clamps.
Vuam tshuab cablesfeature ib qho -cov tub ntxhais kev tsim kho, feem ntau suav nrog ntau cov xov tooj ntawm tooj liab. Ob peb li strands tsim tus neeg xyuas pib ntawm lub vuam tshuab cable; yog li ntawd, YH cables kuj yog tuab, muaj ntau pua ntawm tooj liab xov hlau. Cov strands no nyob ib puag ncig los ntawm txheej cua sov- tiv thaiv polyester zaj duab xis rwb thaiv tsev. Cov txheej txheej rwb thaiv tsev feem ntau yog ua los ntawm cov roj hmab ntuj, thaum cov xov tooj hlau yog cov pa oxygen - tooj liab dawb; qhov no ua kom ob qho tib si zoo heev hluav taws xob conductivity ntawm cov tub ntxhais thiab kev nyab xeeb ntawm lub cable.
Piv nrog rau cov kab hluav taws xob hauv tsev,vuam cablesyog cov yoog raws, muaj zog dua thiab muaj peev xwm tiv taus cov dej ntws siab, ua rau lawv tsim nyog rau kev rub thiab khoov koom nrog hauv vuam.
2, Vim li cas vuam cables tseem ceeb rau vuam?
Vuam cablesyog qhov tseem ceeb thaum lub sij hawm vuam txheej txheem, vim lawv tsis yog tsuas yog ua hauj lwm raws li conduits rau high tam sim no tab sis kuj yog 'cov cuab yeej tshwj xeeb' tshwj xeeb tsim los tiv thaiv qhov nyuaj thiab hnyav ntawm qhov chaw vuam. Yog tsis muaj lawv, kev ua haujlwm vuam tsis tuaj yeem ua tau zoo thiab ntseeg tau.
Tshwj xeeb, nws irreplaceability yog tshwm sim nyob rau hauv cov nram qab no yam
Vuam cables yog 'cov hlab ntsha' uas nqa hluav taws xob tam sim no:
'Special rog' ua rau hnyav ib puag ncig:
Tus neeg xyuas pib:Tsim los ntawm ntau cov hlua ntawm ultra- zoo nkauj liab qab tooj liab hlau twisted ua ke, qhov no ua kom lub cable khaws cia zoo heev yooj yooj yim txawm nyob rau hauv nquag txav thiab twisting, yooj yim rau kev siv rau welders. Tsis tas li ntawd, kev siv cov khoom siv xws li cov pa oxygen- tooj liab dawb tiv thaiv cov neeg xyuas pib tawg los ntawm cov hlau qaug zog thaum rov khoov dua, ua kom muaj hluav taws xob ruaj khov.
Insulation thiab Sheathing:Cov roj hmab sab nrauv (xws li cov khoom tshwj xeeb- lub hom phiaj roj hmab lossis cov khoom siv nitrile sib xyaw) ua raws li nws 'tus neeg saib xyuas'. Nws yuav tsum muaj kua muag - thiab abrasion - cov khoom tiv thaiv kom tiv taus khawb los ntawm cov khoom siv hlau ntse; nws kuj yuav tsum yog roj-resistant, dej-resistant, UV-resistant thiab resistant rau acids thiab alkalis los tiv thaiv cov chaw tsim kho. Qhov kev tiv thaiv ruaj khov no tsis sib haum los ntawm cov hluav taws xob zoo tib yam.
Tus 'tus neeg saib xyuas' ntawm kev nyab xeeb thiab siv tau
Kev nyab xeeb hluav taws xob: Lub rwb thaiv tsev ntawm cov vuam cables zoo tiv thaiv qhov ntsuas hluav taws xob txog li 1,000 V, ua kom tus neeg teb xov tooj muaj kev nyab xeeb thiab tiv thaiv hluav taws xob poob siab.
Thermal stability: Thaum cov hluav taws xob siab dhau mus, lub cable nws tus kheej ua kom sov. Certified welding cables tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev ntawm qhov kub siab ntawm 65℃lossis txawm 90℃yam tsis muaj melting lossis deteriorating vim overheating, yog li tsis txhob siv hluav taws xob thiab kev nyab xeeb.
Lightweight thiab Flexible: Txhawm rau txo lub cev hnyav ntawm cov welders, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum muaj kev txav mus los xws li kev tsim cov nkoj thiab kev tsim kho choj, cov hlua vuam niaj hnub niaj hnub tau tsim los ua kom sib dua. Piv txwv li, cables siv high-lub zog aluminium conductors es tsis txhob tooj liab tuaj yeem txo qhov hnyav li ntawm 50%, ua rau vuam ua haujlwm yooj yim dua thiab ua haujlwm zoo dua.
Hauv luv luv, avuam kabtsis yog ib qho yooj yim xaim; Nws muab cov khoom siv hluav taws xob zoo, tshwj xeeb tshaj plaws thiab kev tiv thaiv kev tiv thaiv, ua qhov tseem ceeb ntawm kev sib txuas ntawm cov khoom siv hluav taws xob thiab qhov chaw vuam, yog li ua kom muaj kev sib tw ntawm cov txheej txheem vuam thiab kev nyab xeeb ntawm tus neeg teb xov tooj.
3, Kev faib tawm ntawm vuam tshuab cables
- Los ntawm daim ntawv thov (yooj yim yooj yim to taub): welding torch cable (txuas lub welder rau lub teeb; yuav tsum tau hloov tau yooj yim thiab yooj yim los tuav), lub ntiaj teb cable (txuas lub welder rau lub ntiaj teb; xyuas kom muaj kev nyab xeeb)
- Los ntawm cov khoom siv (tseem ceeb rau ntau hom): tooj liab core (feem ntau siv; zoo conductivity; ruaj), aluminium core (tsawg dua; tsis tshua muaj nqi; haum rau lub teeb- daim ntawv thov lub luag haujlwm)
- Los ntawm hom rwb thaiv tsev (qhov sib txawv yooj yim): roj hmab sheath ( yoog raws, tshav kub-tiv taus, feem ntau siv hauv kev siv niaj hnub), lwm yam ntaub ntawv

5, Xaus
Raws li sub-sector ntawm fais fab cables,vuam cablesyog cov khoom siv tseem ceeb rau kev ua haujlwm vuam; lawv cov kev ua tau zoo cuam tshuam ncaj qha rau vuam zoo, kev nyab xeeb kev ua haujlwm thiab kev ua haujlwm zoo, thiab lawv tau siv dav hauv ntau qhov chaw tseem ceeb.
Tau txais kev nkag siab zoo ntawm kev lag luam welding cable-los ntawm cov ntsiab lus tseem ceeb, kev faib khoom thiab cov ntsiab lus tseem ceeb rau kev lag luam cov ntsiab lus thiab kev loj hlob zoo- tsis yog tsuas yog pab cov kws tshaj lij xaiv cov khoom tsim nyog thiab siv lawv kom raug, tab sis kuj ua rau lawv paub meej txog txoj hauv kev ntawm kev lag luam txoj kev loj hlob, ua hauj lwm rau yav tom ntej. Yav tom ntej, raws li thev naus laus zis hloov zuj zus thiab kev lag luam xav tau nce ntxiv, kev lag luam vuam cable yuav pom dav dav rau kev loj hlob, thaum tseem muab cov kev xav tau siab dua ntawm kev paub txog cov neeg ua haujlwm hauv kev lag luam.
