** Thaum nws los txog rau cable tswj systems, ob qho kev xaiv nrov tshaj plaws yog cable tais thiab troughs. Txawm hais tias lawv yuav tshwm sim zoo sib xws, lawv yeej muaj lawv tus kheej qhov sib txawv thiab cov txiaj ntsig. Hauv tsab xov xwm no, peb yuav tshawb xyuas dab tsi teeb tsa cable tais thiab troughs sib nrug.**
Ua ntej, cia peb txhais tias lub tais cable yog dab tsi. Nws yog qhov qhib-sab thiab qhov cua uas yog tsim los txhawb, tiv thaiv thiab teeb tsa hluav taws xob cables thiab xov hlau. Cable tais tuaj yeem siv rau ntau qhov chaw, suav nrog kev lag luam, kev lag luam, thiab chaw nyob.
Ib lub trough, ntawm qhov tod tes, yog ib hom hluav taws xob txuas hluav taws xob uas siv rau hauv tsev thiab tiv thaiv cov xov hlau thiab cables. Nws feem ntau yog ua los ntawm cov ntaub ntawv nruj xws li steel lossis PVC thiab tuaj yeem ntsia tau rau saum toj thiab hauv qab av.
Ib qho ntawm qhov sib txawv loj tshaj plaws ntawm cov tais cable thiab troughs yog lawv cov qauv tsim thiab kev tsim kho.
Cable tais feem ntau yog ua los ntawm cov hlau, txhuas, los yog fiberglass, thiab yog tsim los ua lub teeb yuag thiab yooj yim rau nruab. Lawv muaj xws li ib tug series ntawm interconnected hlau los yog yas kev txhawb nqa uas yog teem nyob rau hauv ib daim phiaj-zoo li tus qauv. Cov kev txhawb nqa no tsim cov channel lossis rungs uas tso cai rau cov kab hluav taws xob tso rau hauv ib qho kev teeb tsa.
Troughs, ntawm qhov tod tes, feem ntau yog ua los ntawm cov ntaub ntawv nruj xws li steel lossis PVC, thiab tsim los muab kev tiv thaiv ntau dua rau cables. Lawv feem ntau ntsia hauv av, thiab lawv feem ntau siv nyob rau hauv qhov chaw sab nraum zoov uas lawv yuav raug rau cov ntsiab lus.
Lwm qhov sib txawv ntawm cable tais thiab troughs yog lawv daim ntawv thov.
Cable tais feem ntau siv nyob rau hauv kev lag luam chaw, qhov chaw uas lawv muaj peev xwm txhawb nqa ib tug loj tus naj npawb ntawm cables thiab nyob ntawm tej. Lawv kuj zoo tagnrho rau cov ntawv thov uas cov cables yuav tsum tau yooj yim nkag mus rau kev kho lossis kho. Cable tais tuaj yeem ntsia tau rau ntawm phab ntsa, qab nthab, lossis hauv pem teb, ua rau lawv muaj ntau yam kev xaiv rau kev tswj cable.
Troughs feem ntau yog siv nyob rau hauv qhov chaw sab nraum zoov lossis hauv cov ntawv thov uas yuav tsum muaj kev teeb tsa hauv av. Lawv feem ntau siv rau hauv kev tsim kho vaj tse thiab kev tsim dej, nrog rau hauv kev lag luam kev sib txuas lus rau fiber ntau cables. Troughs kuj yog ib qho kev xaiv rau vaj tse nyob rau hauv cov cheeb tsam uas lawv yuav raug kub los yog lwm yam ib puag ncig.
Qhov thib peb qhov sib txawv ntawm cable tais thiab troughs yog lawv lub peev xwm thiab kev muaj peev xwm thauj khoom.
Cable tais feem ntau yog ntsuas rau lawv lub peev xwm thauj khoom, lossis qhov hnyav uas lawv tuaj yeem txhawb nqa. Nyob ntawm cov khoom siv thiab tsim, cov tais cable tuaj yeem txhawb nqa ntau yam ntawm qhov hnyav, los ntawm ob peb phaus mus rau ob peb tons.
Troughs, ntawm qhov tod tes, feem ntau yog tsim los kom haum rau tus lej tshwj xeeb thiab qhov loj ntawm cov cables. Lawv tsis yog feem ntau ntsuas rau lub peev xwm thauj khoom, vim lawv tsis tau npaj los txhawb nqa hnyav.
Lwm qhov sib txawv ntawm cable tais thiab troughs yog lawv cov nqi.
Cable tais feem ntau tsis tshua kim tshaj li troughs, vim lawv yog ua los ntawm cov ntaub ntawv sib zog thiab yooj yim rau nruab. Lawv kuj muaj ntau yam ntxiv, raws li lawv tuaj yeem siv rau ntau yam kev siv.
Troughs, ntawm qhov tod tes, feem ntau kim dua vim lawv cov haujlwm hnyav thiab xav tau kev teeb tsa hauv av. Lawv feem ntau siv rau hauv cov ntawv thov uas qhov kev ua haujlwm ntev thiab kev ua haujlwm ntev yog qhov tseem ceeb.
Qhov kawg qhov sib txawv ntawm cable tais thiab troughs yog lawv tu thiab tu.
Cable tais yuav tsum tau saib xyuas tsawg thiab yooj yim los ntxuav thiab tshuaj xyuas. Lawv kuj yooj yim rau kev nkag mus, uas ua rau nws yooj yim rau ntxiv lossis tshem cov cables raws li xav tau.
Troughs, ntawm qhov tod tes, xav tau kev saib xyuas ntau dua vim lawv cov kev teeb tsa hauv av. Lawv yuav tsum tau tshuaj xyuas tsis tu ncua kom ntseeg tau tias lawv tsis raug puas tsuaj los ntawm dej, khib nyiab, lossis lwm yam ib puag ncig. Thaum yuav tsum tau kho, nws tuaj yeem nyuaj dua thiab siv sij hawm nkag mus rau cov cables hauv lub trough.
Hauv kev xaus, thaum cable tais thiab troughs yuav tshwm sim zoo sib xws, lawv muaj qhov sib txawv loj hauv lawv cov qauv tsim, daim ntawv thov, thiab tus nqi. Kev xaiv txoj cai tswj hwm cable yog nyob ntawm cov kev xav tau tshwj xeeb thiab cov kev xav tau ntawm koj qhov project. Los ntawm kev nkag siab txog qhov zoo thiab qhov tsis zoo ntawm txhua qhov system, koj tuaj yeem ua qhov kev txiav txim siab uas ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm koj cov khoom siv hluav taws xob thiab cov xov hlau.
