Cov kab ntawv tshaj tawm yuav zoo li ua tiav thaum xub thawj siab ib muag. Tab sis thaum koj nkag siab lawv cov tseem ceeb, lawv cov qauv tsim ua kom muaj txiaj ntsig zoo rau cov fiber ntau optic nruab.
Cov ntawv tshaj tawm muaj ntau txheej: lub zog nruab nrab ntawm cov tswv cuab, kho qhov muag cov khoom siv, cov khoom siv ua dej, ntxiv rau sab nraud tiv thaiv sheatos. Txhua txheej ua haujlwm rau kev ua haujlwm tseem ceeb los xyuas kom ntseeg tau tias muaj kev ua tau zoo hauv kev ua si sab nraud.
Rau cov neeg ua haujlwm network thiab cov faib khoom siv, paub txog cov khoom siv tsis yog tsuas yog ua tsis muaj peev xwm. Nws pab hauv kev xaiv txoj cai tshaj tawm cable rau cov phiaj xwm tshwj xeeb thiab voltage ib puag ncig. Cia kuv piav txhua qhov tseem ceeb hauv kev nthuav dav.
Dab tsi yog tus tseem ceeb lub zog tswvcuab hauv kev tshaj tawm cables?
Qhov chaw ntawm txhua cov kev tshaj tawm cable yuav tsum tiv taus ntau yam nruj. Qhov ntawd yog qhov chaw nruab nrab lub zog (CSM) los rau hauv.
Lub CSM, feem ntau cov fiberglass txhawb cov yas (FRP) Qws, muab kev txhawb nqa kev ua haujlwm ua haujlwm rau tag nrho cable qauv. Nws tuav lub tensile loads yam tsis muaj ncab lossis tawg thaum lub sijhawm teeb tsa thiab kev pabcuam lub neej.
CSM lub luag haujlwm yog qhov tseem ceeb vim tias:
Thauj Khoom
Nws tusyees faib cov rog no hla kev sib txuas ntev
Tsis-conductive cov yam ntxwv
FRP cov khoom siv kom muaj hluav taws xob cais los ntawm cov kab hluav taws xob
Thermal ruaj khov
Saib xyuas cov qauv txheej txheem hauv qab kub hloov pauv
Cov kev qhia yuam kev rau CSM suav nrog:
Yuav ua li cas yog kho qhov muag fibers tiv thaiv nyob rau hauv cov tshaj xab cab?
Kev siv kho qhov muag yog qhov muag heev, tsis tau tshaj tawm cov cable dai tau rau cov khoom. Qhov no yuav tsum muaj kev tiv thaiv fiber fiberional fiber ntau.
Cov fibers yog nyob rau hauv cov xim tsis zoo, nrog txhua lub raj muaj 2-24 fibers. Cov leeg no yog ntim nrog dej-thaiv gel lossis siv cov tshuab dej qhuav qhuav los muab txoj kev tiv thaiv thiab kev tiv thaiv noo noo.
Niaj hnub Adss cov qauv tsim ua ntej kev nyab xeeb fiber ntau
- Loe raj tsim: Tso cai rau cov fibers txav me ntsis, tiv thaiv cov microbently poob
- Xim Coling: Txhua lub raj muaj cov xim txawv rau cov cim yooj yim
- Tshaj fiber ntau: Feem ntau {0. {5-1% ntev dua li cable hloov
Koom haum tsis zoo cov raj teeb:
Yuav ua li cas cov adss cables tau ua tiav dej tsis kam?
Dej yog nyob ntawm cov ntsiab lus tshaj plaws rau cov cab ntau. Adss tsim kev sib tw ua dej noo ingress ntawm ntau qib.
Peb-chav dej tiv thaiv dej yog qauv: dej-thaiv cov leeg, tapes nruab nrab ntawm txheej, thiab dej-resistant sab nraud sheathing. Qhov kev tiv thaiv ntau-tiv thaiv tiv thaiv cov dej tsiv teb tsaws txawm tias cov hmoov txhuas sab nraud puas tsuaj.
Kev tiv thaiv noo noo suav nrog:
- Cov Dej Thaiv
Hydrophobic gels hauv tub leeg
Superabsorbent polymers (sap) hauv cov qauv qhuav
- InterstTitial breat
Offing tapes nruab nrab ntawm lub zog txheej
Dej-thaiv cov xov paj qhwv cov tsiaj qhwv
- Sab nraud tiv thaiv
Nruab nrab / siab ntom polyethylene sheaths
Cov tshuaj ntxiv tshwj xeeb rau hydrophobicity
Cov qauv dej tseem ceeb rau cov ADSS cables:
Iec {60794-1-2- f1 (ntev kev nkag mus ntev)
Telcordia gr {0}}} (noo noo tsis kam)
ICAA s -104-696 (dej thaiv kev yuav tsum tau)
Kev siv cov tshuab puas muaj zog ensured hauv cov adss cables?
Tshaj li ntawm Central Tswvcuab, ADSS CABLES CABLES CASS txuas ntxiv ntxiv dag zog rau cov ntsiab lus los lis cov khoom siv hluav taws xob tsis muaj zog.
High-tensile aramid xov (Kevlar) lossis khob xov paj vajtse muab cov txheej txheem theem nrab. Cov ntaub ntawv no yog lub teeb, tsis yog xim hlau, thiab muab cov kev tshwj xeeb muaj zog-rau-luj txoj kev sib piv rau cov khoom tseem ceeb.
Cov tshuab kho tshuab qhov cuab lub zog ua haujlwm pabcuam peb lub hom phiaj tseem ceeb:
Kev Cuam Tshuam: Cov Tub Ceev Xwm tiv thaiv cov noog ntaus, cua tshuab tshuab hluav taws xob
Dhuav Damping: Minimizes kev puas tsuaj los ntawm cua-induced oscillation
Kev Tiv Thaiv Kev Tiv Thaiv Kev Nyab Xeeb: Tiv thaiv sheath kev puas tsuaj thaum rub
Raug zog specifications:
Lub luag haujlwm ntawm cov hnab riam sab nraud hauv cov tshaj tawm?
Lub sheath yog lub cable thawj kab ntawm kev tiv thaiv kev muaj kev cov nyom ib puag ncig.
Lub ntsej muag sab nraud muab kev tiv thaiv zoo: UV tiv thaiv kev txwv, thiab cov khoom siv tshwj xeeb tiv thaiv ntev ntev thaum nruab ze cov kab hluav taws xob.
SHOORAM Cov ntaub ntawv xaiv kev xaiv:
Hluav Taws Xob Ib puag ncig: Cov qauv sib txawv rau ntau cov chav kawm hluav taws xob:

High voltage (>66KV): Cov qauv tshwj xeeb tiv thaiv Corona
Environmentalency:
UV Stabilizers rau hnub ci
Hydrophobic additives rau ntub huab cua
Nplaim taws-retardant tebchaw rau cov chaw tua hluav taws
Sheath tuab ib txwm ua raws li:
Tag
Cov Cabs Cables ua ke ntau yam tshwj xeeb los tsim cov kev daws teeb meem aerable. Kev nkag siab cov qauv no pab xaiv cov qoob loo uas ua tau raws li cov phiaj xwm tshwj xeeb.
