Txhawm rau tiv thaiv kev ruaj khov ntawm cov qauv thiab kev ua haujlwm hluav taws xob ntawm cov cables thiab kom ntev lawv lub neej kev pabcuam, ib txheej armor tuaj yeem ntxiv rau lub sheath sab nraud ntawm lub cable. Feem ntau muaj ob hom cable armor:daim kab xev hlauriam phom thiabhlau hlauriam phom.
Yuav kom cov cables tiv taus lub zog radial, siv ob daim kab xev hlau nrog cov txheej txheem qhwv qhov sib txawv - qhov no hu ua steel tape armored cable. Tom qab cabling, steel tapes raug qhwv ib ncig ntawm lub cable core, ua raws li extrusion ntawm lub hnab yas. Cov qauv cable siv cov qauv no suav nrog cov cables tswj xws li KVV22, cov cables fais fab xws li VV22, thiab cov cables sib txuas lus xws li SYV22, thiab lwm yam. Ob tus lej Arabic hauv hom cable qhia cov hauv qab no: thawj "2" sawv cev rau ob daim kab xev hlau armor; qhov thib ob "2" sawv cev rau PVC (Polyvinyl Chloride) sheath. Yog tias siv PE (Polyethylene) sheath, tus lej thib ob hloov mus rau "3". Cov cables ntawm hom no feem ntau siv rau hauv qhov chaw siab, xws li kev hla kev, plazas, kev co-prone ntug kev lossis txoj kev tsheb ciav hlau, thiab tsim nyog rau kev faus ncaj qha, tunnels, lossis conduit installations.
Yuav kom pab cov cables tiv taus qhov siab dua axial tension, ntau cov hlau carbon tsawg-carbon hlau yog helically qhwv ib ncig ntawm lub cable core - qhov no hu ua hlau hlau armored cable. Tom qab cabling, cov hlau hlau yog qhwv nrog ib lub suab tshwj xeeb thiab ib lub sheath yog extruded hla lawv. Cov hom cable siv cov qauv no suav nrog cov tswj cables xws li KVV32, cov fais fab cables xws li VV32, thiab coaxial cables xws li HOL33. Ob tug lej Arabic hauv tus qauv sawv cev rau: thawj "3" qhia txog hlau hlau armor; qhov thib ob "2" qhia txog PVC sheath, thiab "3" qhia txog PE sheath. Hom cable no feem ntau yog siv rau kev teeb tsa ntev lossis qhov twg muaj qhov poob ntsug tseem ceeb.
Kev Ua Haujlwm ntawm Cov Cables Armored
Cov xov hlau uas muaj hlau tiv thaiv yog cov xov hlau uas muaj hlau tiv thaiv. Lub hom phiaj ntawm kev ntxiv hlau tiv thaiv tsis yog tsuas yog txhim kho lub zog tensile thiab compressive thiab txuas ntxiv lub zog kho tshuab, tab sis kuj txhim kho kev cuam tshuam electromagnetic (EMI) los ntawm kev tiv thaiv.
Cov ntaub ntawv siv los ua armoring feem ntau muaj xws li steel tape, steel wire, aluminium tape, thiab aluminium tube. Ntawm lawv, steel tape thiab steel wire muaj magnetic permeability siab, muab cov magnetic shielding zoo, tshwj xeeb tshaj yog zoo rau kev cuam tshuam tsawg zaus. Cov ntaub ntawv no tso cai rau cov cable kom raug faus ncaj qha yam tsis muaj conduits, ua rau lawv yog cov kev daws teeb meem pheej yig thiab siv dav.
Cov txheej txheem tiv thaiv no siv tau rau txhua lub qauv cable kom txhim kho lub zog thiab kev tiv thaiv xeb, ua rau nws zoo tagnrho rau thaj chaw uas yuav raug kev puas tsuaj los ntawm kev kho tshuab lossis ib puag ncig hnyav. Nws tuaj yeem tso rau hauv txhua txoj kev thiab tshwj xeeb tshaj yog tsim rau kev faus ncaj qha hauv cov av pob zeb. Hais yooj yim, cov xov hlau tiv thaiv yog cov xov hlau hluav taws xob tsim los rau kev siv faus lossis hauv av. Rau cov xov hlau xa hluav taws xob, cov hlau tiv thaiv ntxiv lub zog tensile thiab compressive, tiv thaiv cov xov hlau los ntawm cov zog sab nraud, thiab txawm tias pab tiv thaiv kev puas tsuaj ntawm nas, tiv thaiv kev tom los ntawm cov hlau tiv thaiv uas yuav cuam tshuam kev xa hluav taws xob. Cov xov hlau tiv thaiv xav tau lub vojvoog khoov loj dua, thiab cov txheej txheem tiv thaiv kuj tseem tuaj yeem raug av rau kev nyab xeeb.
IB LUB NTIJ TEB Tshwj Xeeb Hauv Cov Khoom Siv Cable Zoo
Peb muab ntau yam khoom siv tiv thaiv—xws li daim kab xev hlau, hlau hlau, thiab daim kab xev txhuas—siv dav hauv cov xov hluav taws xob fiber optic thiab cov xov hluav taws xob rau kev tiv thaiv cov qauv thiab kev ua haujlwm zoo dua. Txhawb nqa los ntawm kev paub dhau los thiab lub kaw lus tswj xyuas zoo, ONE WORLD cog lus tias yuav muab cov khoom siv txhim khu kev qha thiab sib xws uas pab txhim kho kev ruaj khov thiab kev ua haujlwm tag nrho ntawm koj cov khoom siv cable.
Xav tiv tauj peb kom paub ntxiv txog cov khoom thiab kev txhawb nqa kev siv tshuab.
