Cov yam ntxwv ntawm cov khoom siv hlau thiab cable feem ntau tuaj yeem muab faib ua plaub qhov tseem ceeb:tus thawj coj, rwb thaiv tsev txheej, shielding thiab tiv thaiv cov khaubncaws sab nraud povtseg, nrog rau cov khoom ntim thiab tensile ntsiab. Raws li cov kev xav tau ntawm kev siv thiab kev siv cov xwm txheej, qee cov khoom tsim tau yooj yim heev, tsuas yog muaj cov khoom siv hluav taws xob, xws li cov khoom siv hluav taws xob sab nraud, cov xov hlau sib txuas, tooj liab-aluminium busbars (busbars), thiab lwm yam. cov khoom cia siab rau cov insulators thaum lub sij hawm installation thiab spatial nrug (piv txwv li, cua rwb thaiv tsev) kom muaj kev ruaj ntseg.
1. Tus coj
Cov khoom siv hluav taws xob yog qhov tseem ceeb tshaj plaws thiab tseem ceeb tshaj plaws ntawm cov khoom lag luam uas cuam tshuam rau kev xa cov ntaub ntawv hluav taws xob tam sim no lossis cov ntaub ntawv hluav taws xob hauv cov khoom siv. Cov neeg siv hluav taws xob, feem ntau hu ua conductive hlau cores, yog tsim los ntawm high-conductivity non-ferrous hlau zoo li tooj liab, txhuas, thiab lwm yam. Fiber optic cables siv nyob rau hauv evolving optical kev sib txuas lus network sai sai nyob rau hauv peb caug xyoo dhau los siv optical fibers ua conductors.
2. Cov txheej txheem rwb thaiv tsev
Cov khoom no envelop lub conductors, muab hluav taws xob rwb thaiv tsev. Lawv xyuas kom meej tias tam sim no lossis electromagnetic / optical waves kis tau tsuas yog taug kev raws tus neeg xyuas pib thiab tsis yog sab nraud. Cov txheej rwb thaiv tsev tuav lub peev xwm (piv txwv li, qhov hluav taws xob) ntawm tus neeg xyuas pib los ntawm kev cuam tshuam cov khoom nyob ib puag ncig thiab ua kom ob qho tib si kis tau tus mob ntawm tus neeg xyuas pib thiab kev nyab xeeb sab nraud rau cov khoom thiab tib neeg.
Cov khoom siv hluav taws xob thiab cov txheej thaiv rwb thaiv tsev yog ob qho tseem ceeb ntawm cov khoom tsim nyog rau cov khoom siv cable (tshwj tsis yog cov xov hlau liab qab).
3. Cov txheej txheem tiv thaiv
Nyob rau hauv ntau yam ib puag ncig thaum lub sij hawm installation thiab kev ua hauj lwm, cov khoom siv hlau thiab cable yuav tsum muaj cov khoom uas muaj kev tiv thaiv, tshwj xeeb tshaj yog rau txheej rwb thaiv tsev. Cov khoom no hu ua cov txheej tiv thaiv.
Vim hais tias cov ntaub ntawv rwb thaiv tsev yuav tsum muaj cov khoom siv hluav taws xob zoo heev, lawv xav tau cov purity siab nrog cov ntsiab lus tsawg tsawg. Txawm li cas los xij, cov ntaub ntawv no feem ntau tsis tuaj yeem muab kev tiv thaiv los ntawm cov khoom siv sab nraud (piv txwv li, cov khoom siv hluav taws xob thaum lub sijhawm teeb tsa thiab siv, tiv thaiv huab cua, tshuaj lom neeg, roj, kev hem thawj lom neeg, thiab hluav taws kub). Cov kev cai no yog tswj hwm los ntawm ntau cov txheej txheem tiv thaiv.
Rau cov kab hluav taws xob tsim tshwj xeeb rau qhov chaw zoo sab nraud (xws li, huv, qhuav, qhov chaw sab hauv tsev tsis muaj cov khoom siv sab nraud), los yog nyob rau hauv cov ntaub ntawv uas cov txheej txheem rwb thaiv tsev nws tus kheej nthuav tawm qee yam khoom siv dag zog thiab kev tiv thaiv huab cua, tej zaum yuav tsis tas yuav muaj cov txheej txheem tiv thaiv zoo li. ib feem.
4. Tiv thaiv
Nws yog ib feem ntawm cov khoom siv cable uas cais cov electromagnetic teb nyob rau hauv lub cable los ntawm sab nraud electromagnetic teb. Txawm hais tias ntawm cov hlau sib txawv los yog pab pawg hauv cov khoom siv cable, kev sib cais yog tsim nyog. Cov txheej thaiv npog tuaj yeem piav qhia tias yog "kev tshuaj ntsuam hluav taws xob hluav taws xob sib cais."
Tau ntau xyoo, kev lag luam tau suav tias cov txheej txheem tiv thaiv yog ib feem ntawm cov txheej txheem tiv thaiv. Txawm li cas los xij, nws tau hais tias nws yuav tsum raug suav hais tias yog ib qho kev sib cais. Qhov no yog vim qhov kev ua haujlwm ntawm cov txheej thaiv thaiv tsis yog tsuas yog txhawm rau electromagnetically cais cov ntaub ntawv xa mus rau hauv cov khoom siv cable, tiv thaiv nws los ntawm kev xau lossis ua rau cuam tshuam rau cov cuab yeej sab nraud lossis lwm cov kab, tab sis kuj tseem tiv thaiv cov khoom siv hluav taws xob sab nraud los ntawm kev nkag mus rau hauv cov khoom siv cable los ntawm electromagnetic coupling. Cov kev cai no txawv ntawm cov txheej txheem tiv thaiv ib txwm muaj. Tsis tas li ntawd, cov txheej thaiv thaiv tsis yog tsuas yog teem rau sab nraud hauv cov khoom, tab sis kuj muab tso rau ntawm txhua tus khub hlau lossis ntau khub hauv ib lub cable. Xyoo kaum xyoo dhau los, vim muaj kev loj hlob sai ntawm cov ntaub ntawv xa xov hluav taws xob siv cov xov hlau thiab cables, nrog rau cov khoom siv hluav taws xob sib nqus yoj cuam tshuam ntau ntxiv hauv cov huab cua, ntau yam ntawm cov txheej txheem tiv thaiv tau ntau ntxiv. Kev nkag siab tias txheej thaiv thaiv yog ib qho tseem ceeb ntawm cov khoom siv cable tau dhau los lees txais.
Ntau cov khoom siv hlau thiab cable yog ntau cov tub ntxhais, xws li feem ntau cov hluav taws xob qis hluav taws xob yog plaub-core lossis tsib-core cables (tsim rau peb-theem systems), thiab cov xov tooj hauv nroog xws li 800 khub txog 3600 khub. Tom qab sib txuas cov insulated cores los yog hlau khub rau hauv ib lub cable (los yog ntau lub sij hawm sib koom ua ke), cov duab tsis zoo thiab qhov khoob loj muaj nyob nruab nrab ntawm cov insulated cores lossis hlau khub. Yog li ntawd, ib tug filling qauv yuav tsum tau muab tso rau thaum lub sij hawm sib dhos cable. Lub hom phiaj ntawm cov qauv no yog kom tswj tau ib qho kev sib thooj sab nraud hauv coiling, yooj yim qhwv thiab sheath extrusion. Ntxiv mus, nws ua kom muaj kev ruaj ntseg ntawm cable thiab cov qauv hauv kev ncaj ncees, faib cov zog sib npaug thaum siv (stretching, compression, thiab dabtsi yog khoov thaum tsim khoom thiab tso) kom tsis txhob muaj kev puas tsuaj rau cov kab hauv cov qauv.
Yog li ntawd, txawm hais tias cov qauv filling yog pab, nws yog qhov tsim nyog. Cov kev cai ntxaws muaj nyob rau ntawm kev xaiv cov khoom siv thiab kev tsim cov qauv no.
Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob feem ntau cia siab rau cov txheej txheem armored ntawm cov txheej txheem tiv thaiv kom tiv thaiv sab nraud tensile rog lossis qhov nro los ntawm lawv tus kheej qhov hnyav. Cov qauv tsim muaj xws li steel daim kab xev armoring thiab steel hlau armoring (xws li siv 8 hli tuab steel hlau, twisted rau hauv ib txheej armored, rau submarine cables). Txawm li cas los xij, nyob rau hauv fiber ntau optical cables, los tiv thaiv cov fiber ntau los ntawm me tensile rog, tsis txhob muaj me ntsis deformation uas yuav cuam tshuam rau kev sib kis tau zoo, thawj thiab theem nrab coatings thiab tshwj xeeb tensile Cheebtsam yog incorporated rau hauv lub cable qauv. Piv txwv li, nyob rau hauv lub xov tooj ntawm tes headset cables, ib tug zoo tooj liab hlau los yog nyias tooj liab daim kab xev nyob ib ncig ntawm hluavtaws fiber yog extruded nrog ib tug insulating txheej, qhov twg cov hluavtaws fiber ua raws li ib tug tensile tivthaiv. Zuag qhia tag nrho, nyob rau hauv xyoo tas los no, nyob rau hauv kev tsim tshwj xeeb me me thiab saj zawg zog cov khoom uas yuav tsum tau ntau yam khoov thiab twists, tensile ntsiab ua lub luag hauj lwm tseem ceeb.
