Peb paub tias cov cables sib txawv muaj kev ua tau zoo sib txawv thiab yog li ntawd cov qauv sib txawv. Feem ntau, ib lub cable yog tsim los ntawm tus neeg coj hluav taws xob, txheej tiv thaiv, txheej rwb thaiv tsev, txheej plhaub, thiab txheej tiv thaiv. Nyob ntawm cov yam ntxwv, cov qauv sib txawv. Txawm li cas los xij, ntau tus neeg tsis meej txog qhov sib txawv ntawm kev rwb thaiv tsev, kev tiv thaiv, thiab txheej plhaub hauv cov cables. Cia peb rhuav tshem lawv kom nkag siab zoo dua.
(1) Txheej rwb thaiv tsev
Cov txheej rwb thaiv tsev hauv ib lub cable feem ntau muab kev rwb thaiv tsev ntawm tus neeg coj thiab ib puag ncig lossis cov neeg coj uas nyob ib sab. Nws ua kom ntseeg tau tias cov hluav taws xob tam sim no, cov nthwv dej electromagnetic, lossis cov teeb liab pom kev uas tus neeg coj nqa tsuas yog xa mus raws tus neeg coj yam tsis muaj kev xau sab nraud, thaum tseem tiv thaiv cov khoom sab nraud thiab cov neeg ua haujlwm. Kev ua tau zoo ntawm cov rwb thaiv tsev txiav txim siab ncaj qha qhov voltage uas lub cable tuaj yeem tiv taus thiab nws lub neej kev pabcuam, ua rau nws yog ib qho ntawm cov khoom tseem ceeb ntawm lub cable.
Cov ntaub ntawv rwb thaiv tsev cable feem ntau tuaj yeem muab faib ua cov ntaub ntawv rwb thaiv tsev yas thiab cov ntaub ntawv rwb thaiv tsev roj hmab. Cov xov hluav taws xob yas rwb thaiv tsev, raws li lub npe qhia, muaj cov txheej rwb thaiv tsev ua los ntawm cov yas extruded. Cov yas feem ntau suav nrog Polyvinyl Chloride (PVC), Polyethylene (PE),Polyethylene sib txuas (XLPE), thiab Low Smoke Zero Halogen (LSZH). Ntawm lawv, XLPE siv dav hauv cov xov hluav taws xob nruab nrab thiab siab vim nws cov khoom siv hluav taws xob thiab kho tshuab zoo heev, nrog rau kev tiv taus kev laus thermal thiab kev ua haujlwm dielectric zoo dua.
Cov xov hluav taws xob uas muaj roj hmab rwb thaiv tsev, ntawm qhov tod tes, yog ua los ntawm roj hmab sib xyaw nrog ntau yam khoom ntxiv thiab ua tiav rau hauv kev rwb thaiv tsev. Cov ntaub ntawv rwb thaiv tsev roj hmab feem ntau suav nrog cov roj hmab sib xyaw ua ke, EPDM (Ethylene Propylene Diene Monomer roj hmab), thiab roj hmab butyl. Cov ntaub ntawv no muaj kev ywj pheej thiab ywj pheej, tsim nyog rau kev txav mus los ntau zaus thiab lub vojvoog me me. Hauv cov ntawv thov xws li kev khawb av, nkoj, thiab chaw nres nkoj, qhov twg kev tiv thaiv kev sib txhuam, kev tiv thaiv roj, thiab kev ywj pheej yog qhov tseem ceeb, cov xov roj hmab rwb thaiv tsev ua lub luag haujlwm tseem ceeb.
(2) Txheej ntawm lub hnab looj tes
Cov txheej txheej sheath ua rau cov cables hloov kho tau rau ntau qhov chaw siv. Siv rau saum cov txheej rwb thaiv tsev, nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov txheej sab hauv ntawm cov cable los ntawm kev puas tsuaj thiab kev xeb ntawm cov tshuaj lom neeg, thaum tseem txhim kho lub zog ntawm cov cable, muab kev tiv thaiv tensile thiab compressive. Cov txheej txheej sheath ua kom cov cable raug tiv thaiv los ntawm kev ntxhov siab ntawm cov tshuab thiab cov yam ntxwv ib puag ncig xws li dej, tshav ntuj, kev xeb ntawm cov kab mob, thiab hluav taws, yog li tswj tau lub sijhawm ntev ntawm kev ua haujlwm hluav taws xob ruaj khov. Qhov zoo ntawm cov txheej txheej sheath ncaj qha cuam tshuam rau lub neej ua haujlwm ntawm cov cable.
Cov txheej sheath kuj tseem tiv taus hluav taws, tiv taus hluav taws, tiv taus roj, tiv taus kua qaub thiab alkali, thiab tiv taus UV. Nyob ntawm seb daim ntawv thov, cov txheej sheath tuaj yeem muab faib ua peb hom tseem ceeb: cov hlau sheaths (suav nrog cov sheath sab nraud), cov roj hmab/yas sheaths, thiab cov composite sheaths. Cov roj hmab/yas thiab cov composite sheaths tsis yog tsuas yog tiv thaiv kev puas tsuaj rau lub tshuab xwb tab sis kuj tseem muaj kev tiv thaiv dej, tiv taus hluav taws, tiv taus hluav taws, thiab tiv taus xeb. Hauv cov chaw ib puag ncig hnyav xws li cov av noo siab, cov qhov av hauv av, thiab cov chaw tsim tshuaj lom neeg, kev ua tau zoo ntawm cov txheej sheath yog qhov tseem ceeb heev. Cov ntaub ntawv sheath zoo tsis yog tsuas yog ua kom lub neej kev pabcuam cable ntev xwb tab sis kuj tseem txhim kho kev nyab xeeb thiab kev ntseeg siab thaum lub sijhawm ua haujlwm.
(3) Txheej Tiv Thaiv
Cov txheej tiv thaiv hauv ib txoj hlua hluav taws xob muab faib ua sab hauv thiab sab nraud. Cov txheej no ua kom muaj kev sib cuag zoo ntawm tus neeg coj thiab rwb thaiv tsev, nrog rau ntawm rwb thaiv tsev thiab sab hauv, tshem tawm qhov muaj zog ntawm lub zog hluav taws xob los ntawm cov nplaim ntxhib ntawm cov neeg coj lossis cov txheej sab hauv. Cov xov hluav taws xob nruab nrab thiab siab feem ntau muaj cov neeg coj thiab rwb thaiv tsev, thaum qee cov xov hluav taws xob qis yuav tsis muaj cov txheej tiv thaiv.
Kev tiv thaiv tuaj yeem yog kev tiv thaiv semi-conductive lossis kev tiv thaiv hlau. Cov qauv tiv thaiv hlau feem ntau suav nrog kev qhwv daim kab xev tooj liab, kev sib txuas hlau tooj liab, thiab kev qhwv daim kab xev txhuas-polyester composite longitudinal. Cov xov hlau tiv thaiv feem ntau siv cov qauv xws li kev tiv thaiv khub sib ntswg, kev tiv thaiv pawg, lossis kev tiv thaiv tag nrho. Cov qauv tsim no muab kev poob dielectric qis, muaj peev xwm kis tau zoo, thiab kev ua tau zoo tiv thaiv kev cuam tshuam zoo heev, ua rau kev xa cov teeb liab analog tsis muaj zog thiab tiv taus kev cuam tshuam electromagnetic muaj zog hauv cov chaw ua haujlwm. Lawv siv dav hauv kev tsim hluav taws xob, metallurgy, roj av, kev lag luam tshuaj lom neeg, kev thauj mus los ntawm tsheb ciav hlau, thiab cov txheej txheem tswj kev tsim khoom tsis siv neeg.
Raws li cov ntaub ntawv tiv thaiv, kev tiv thaiv sab hauv feem ntau siv cov ntawv hlau lossis cov ntaub ntawv semi-conductive, thaum lub tiv thaiv sab nraud yuav muaj cov ntaub qhwv tooj liab lossis cov xov hlau tooj liab braiding. Cov ntaub ntawv braiding feem ntau yog tooj liab liab qab lossis tooj liab tinned, thiab qee zaum cov xov hlau tooj liab-plated nyiaj rau kev txhim kho corrosion thiab conductivity. Ib qho qauv tiv thaiv zoo tsis yog tsuas yog txhim kho kev ua haujlwm hluav taws xob ntawm cov cables tab sis kuj txo cov hluav taws xob electromagnetic cuam tshuam rau cov khoom siv nyob ze. Hauv cov chaw muaj hluav taws xob thiab cov ntaub ntawv niaj hnub no, qhov tseem ceeb ntawm kev tiv thaiv yog qhov tseem ceeb dua.
Xaus lus, cov no yog qhov sib txawv thiab kev ua haujlwm ntawm cov rwb thaiv tsev cable, kev tiv thaiv, thiab cov txheej sheath. IB LUB NTIJ TEB ceeb toom txhua tus tias cov cables muaj feem cuam tshuam nrog lub neej thiab kev nyab xeeb ntawm vaj tse. Cov cables tsis zoo yuav tsum tsis txhob siv; ib txwm nrhiav los ntawm cov chaw tsim khoom cable uas muaj npe nrov.
ONE WORLD tsom mus rau kev muab cov khoom siv raw rau cov cables thiab cog lus tias yuav muab cov neeg siv khoom nrog cov kev daws teeb meem zoo. Peb cov khoom npog ntau yam khoom siv rwb thaiv tsev, hnab, thiab cov ntaub thaiv, xws li XLPE, PVC, LSZH, Aluminium Foil Mylar Daim Kab Xev, Tooj Liab Daim Kab Xev,Daim kab xev mica, thiab ntau ntxiv. Nrog kev ruaj khov zoo thiab kev pabcuam dav dav, peb muab kev txhawb nqa zoo rau kev tsim cov cable thoob ntiaj teb.
