4 Core Armored Cable yog dab tsi?
Thaum nws los txog rau kev teeb tsa hluav taws xob, xaiv txoj cai cable yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab ua haujlwm zoo. Nyob rau hauv tsab xov xwm no, kuv yuav delve rau hauv qhov tshwj xeeb ntawmPlaub cores Aluminium Armored Fais Fab Cable, tshawb nrhiav qhov sib txawv ntawm 3 core thiab 4 core variants thiab tso lub teeb rau ntawm daim ntawv thov ntawm Aluminium Armored Cable.
Nkag siab txog Armored Cables
Armored cables, tseem hu ua armored cables, yog cov hluav taws xob cables tsim nrog ib txheej ntxiv ntawm kev tiv thaiv los txhim kho lawv cov kav ntev thiab tiv thaiv kev puas tsuaj. Ntawm no yog kev tawg ntawm cov khoom, kev tsim kho, thiab kev siv ntawm armored cables:
Kev tsim kho: Armored cables feem ntau muaj ob peb txheej:
Conductors: Cov no yog cov xov hlau uas nqa hluav taws xob tam sim no. Lawv tuaj yeem ua los ntawm tooj liab lossis txhuas, nyob ntawm daim ntawv thov thiab kev xav tau.
Rwb thaiv tsev: Cov conductors yog insulated nrog cov ntaub ntawv xws li PVC (polyvinyl chloride), XLPE (cross-linked polyethylene), los yog EPR (ethylene propylene roj hmab) los tiv thaiv hluav taws xob to thiab muab kev tiv thaiv.
Armor: Lub armor txheej yog qhov kev tiv thaiv ntxiv npog ib ncig ntawm cov insulated conductors. Nws feem ntau yog ua los ntawm cov hlau los yog txhuas hlau los yog cov ntaub qhwv lub qhov txhab nyob ib ncig ntawm lub cable nyob rau hauv ib tug helical los yog interlocking yam. Cov armor muab cov cuab yeej tiv thaiv kev puas tsuaj rau lub cev, suav nrog kev sib tsoo, kev cuam tshuam, thiab kev nkag mus.
Outer Sheath: Qee cov armored cables muaj lub tsho sab nrauv los yog lub tsho ua los ntawm PVC, LSZH (tsis muaj pa taws tsis muaj halogen), lossis lwm yam khoom siv. Lub tsho sab nrauv muab kev tiv thaiv ib puag ncig xws li ya raws, tshuaj lom neeg, thiab UV hluav taws xob.
Hom Armor:
Steel Armored Cable (SWA): Hlau hlau armored cables yog hom armored tshaj plaws. Lawv feature steel xov hlau raug mob nyob ib ncig ntawm cov tub ntxhais cable rau kev tiv thaiv txhua yam.
Aluminium Armored Cable (AWA): Aluminium hlau armored cables siv txhuas hlau rau kev tiv thaiv txhua yam. Lawv sib zog nyob rau hauv qhov hnyav piv rau steel armored cables tab sis muaj kev tiv thaiv zoo sib xws.
Steel daim kab xev Armored Cable: Hloov cov xov hlau, steel daim kab xev armored cables muaj ib tug nruam steel daim kab xev helically mob nyob ib ncig ntawm lub cable core. Lawv muab kev tiv thaiv zoo txhua yam thiab tsim nyog rau qhov chaw hnyav.
Lead Sheathed Cable: Hauv qee qhov kev siv, cov cables yuav muaj cov hlau lead ua ib txheej ntxiv ntawm kev tiv thaiv kev ya raws thiab corrosion. Txawm li cas los xij, hom kab no tsis tshua muaj vim muaj kev txhawj xeeb ntawm ib puag ncig cuam tshuam nrog txhuas.
Qhov txawv ntawm 3 Core thiab 4 Core Armored Cable yog dab tsi?
Ua ntej delving rau hauv cov ntsiab lus ntawmPlaub cores Aluminium Armored Fais Fab Cable, Nws yog ib qho tseem ceeb kom nkag siab qhov sib txawv ntawm 3 core thiab 4 core lwm txoj hauv kev. Hauv cov ntsiab lus yooj yim, tus naj npawb ntawm cov cores yog hais txog cov conductors nyob rau hauv lub cable. Lub 3 core cable muaj peb tus neeg xyuas pib, thaum lub 4 core cable suav nrog plaub.
Thawj qhov sib txawv yog nyob rau hauv daim ntawv thov. 3 core cables feem ntau yog siv rau ib-theem hluav taws xob systems, whereas 4 core cables yog haum rau peb-theem systems. Cov tub ntxhais ntxiv nyob rau tom kawg muab tus neeg xyuas pib ntxiv rau hauv av, txhim kho kev nyab xeeb hauv kev teeb tsa hluav taws xob.
Thaum xaiv ntawm ob, nws yog ib qho tseem ceeb los xav txog cov kev cai tshwj xeeb ntawm cov hluav taws xob hauv cov lus nug. Cov yam ntxwv xws li voltage, load, thiab ib puag ncig tej yam kev mob ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov kev xaiv tsim nyog tshaj plaws.
Dab tsi yog Aluminium Armored Cable Siv Rau?
Tam sim no, cia peb hloov peb txoj kev tsom mus rau Aluminium Armored Cable, ib qho kev xaiv muaj zog thiab ntau yam nyob rau hauv lub cheeb tsam ntawm lub hwj chim cables. Aluminium armoring yog ib qho tseem ceeb feature, muab kev tiv thaiv zoo tiv thaiv kev puas tsuaj thiab ib puag ncig.
Aluminium Armored Cables pom dav siv nyob rau hauv ntau yam kev siv, vim lawv cov kav ntev thiab kev ntseeg tau. Ib qho ntawm cov ntawv thov tseem ceeb yog nyob rau hauv kev teeb tsa hauv av, qhov twg cov cable raug cuam tshuam rau lub cev muaj zog. Lub armor xyuas kom meej tias lub cable tswj nws cov qauv kev ncaj ncees, tiv thaiv cov conductors nyob rau hauv.
Tsis tas li ntawd, cov cables no zoo haum rau kev teeb tsa sab nraum zoov, muab kev tiv thaiv tiv thaiv ya raws, hnub ci, thiab lwm yam khoom ib puag ncig. Qhov no ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm hauv thaj chaw nyuaj lossis huab cua tsis zoo.
Qhov zoo ntawm 4 Core Aluminium Armored Fais Fab Cable
Plaub cores Aluminium Armored Fais Fab Cablemuab ntau yam zoo hauv ntau daim ntawv thov:
