Qauv
Cov kab txuas txuas txuas yog tsim los ntawm cov txheej txheem txheej txheej, hlau armor, puab sheath, muab tub lim, tooj liab shielding txheej, txheej semiconducting txheej, insulating txheej, sab hauv semiconducting txheej, neeg xyuas pib, nyiaj core ntawm cable.Yog li ntawd, cov qauv cable zoo li cas yuav tsum muaj cov khoom siv thiab thev naus laus zis zoo li cas ntawm cov khoom siv cable thiab nws qhov kev sib txuas lus ib leeg thiab sib txuam.
Lub hauv paus ntsiab lus tsim ntawm cable sib koom ua ke yuav tsum ua kom tau raws li qhov yuav tsum tau ua: ua kom lub cable khiav nyab xeeb hauv ib puag ncig ntuj.Yuav kom ua tiav qhov no, nws yuav tsum tau them sai sai rau plaub yam tseem ceeb, xws li: (1) sealing, (2) rwb thaiv tsev, (3) hluav taws xob, (4) txheej txheem thiab lwm yam.Qhov no kuj yog los daws plaub qhov teeb meem tseem ceeb ntawm lub taub hau cable.
Muab kaw
1) Vim tias feem ntau ntawm cov kab txuas txuas txuas tau nruab rau hauv cov kab hluav taws xob sab nraum zoov, hauv av thiab lwm qhov chaw.Yog li ntawd, waterproofing thiab ya raws-pov thawj tau dhau los ua ib qho ntawm cov yuam sij kom ntseeg tau tias kev ua haujlwm ruaj ntseg ntawm cov hlua txuas.Thiab nws cov sealing kev ua tau zoo thiab cov txheej txheem yuav tsum tau txiav txim siab.
Tam sim no, feem ntau muaj ob txoj kev sib khi:
1. ib qho yog txoj kev potting nrog asphalt lossis epoxy resin.Txoj kev no yog qhov nyuaj hauv cov txheej txheem, nyuaj rau kev tswj hwm, thiab tsis tsim nyog rau kev saib xyuas.
2. Lwm txoj kev tshiab, uas tam sim no yog txoj kev nyiam ntawm cov tuam txhab tsim khoom hauv tsev thiab txawv teb chaws, yog siv cov sealants zoo heev.Cov txheej txheem yog yooj yim, kev ua tau zoo yog txhim khu kev qha, thiab cov txij nkawm thiab installation yog yooj yim.Cov txiaj ntsig tshwj xeeb no kuj ua rau nws lub ntsiab ntawm kev siv.
Txhawm rau siv txoj kev tshiab no, thawj qhov yuav tsum tau xav txog yog kev ua haujlwm ntawm cov sealant.Vim tias qhov zoo thiab kev ua tau zoo ntawm cov sealant ncaj qha cuam tshuam rau kev sib khi ua haujlwm ntawm kev sib txuas ntawm cable.Xaiv cov kua nplaum uas tuaj yeem sib txuas nrog rau saum npoo ntawm lub cev cable thiab qhov chaw ntawm cov khoom siv ntxiv kom ruaj khov.Nyob rau tib lub sijhawm, nws yog ib qho tseem ceeb heev uas yuav tsum tau ua kom tau raws li cov kua nplaum uas tuaj yeem siv rau hauv qhov sib txawv ntawm qhov kub thiab txias.
2) Vim hais tias tag nrho txias-shrinkable fais fab cable accessories yog tiag tiag elastic cable accessories.Uas yog hais, lub elasticity ntawm cov kua silicone roj hmab yog siv los nthuav cov yas thiab txhawb nqa strips nyob rau hauv lub Hoobkas ua ntej.Teem nws mus rau qhov chaw xaiv ntawm qhov chaw, thiab rub tawm qhov kev txhawb nqa bar kom txo qis nws ib txwm muaj.Hom tshuab no yog tshuab txias shrinkage, thiab cov khoom siv no yog txias shrinkable cable accessory.Yog li ntawd, qhov txias shrinkable accessory muaj zoo "elasticity".Nws tuaj yeem zam qhov thermal expansion thiab contraction ntawm cable vim qhov chaw nruab nrab ntawm huab cua thiab qib load thaum lub sijhawm ua haujlwm cable.Nws yog kev sib tsoo tawg los ntawm qhov sib txawv ntawm cov rwb thaiv tsev uas tsim los ntawm "cable breathing".Qhov loj tshaj qhov tsis zoo ntawm cov khoom siv cua sov-shrinkable yog tias lawv tsis hloov pauv.Yog li ntawd, tag nrho cov khoom siv txias-shrinkable yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv thaj chaw uas muaj qhov sib txawv ntawm qhov kub thiab txias thiab muaj kev cuam tshuam loj los ntawm huab cua ib puag ncig.
Rwb thaiv tsev
Qhov kev xav tau ntawm rwb thaiv tsev ntawm lub taub hau cable yog ua kom tau raws li ob qho kev rwb thaiv tsev loj ntawm theem-rau-theem rwb thaiv tsev thiab rov qab hauv av.
1. Lub rwb thaiv tsev ntawm theem-rau-theem yog ob yam khoom siv rwb thaiv tsev: silicone roj hmab hom thiab cov khoom siv cua sov-shrinkable.Feem ntau, kev ua haujlwm rwb thaiv tsev yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua raws li qhov ntsuas hluav taws xob rwb thaiv tsev ntawm cov khoom ua ke nrog cov thickness ntawm cov khoom.
2. Lub rwb thaiv tsev ntawm theem mus rau hauv av yog tiv thaiv kom tsis txhob muaj kev nce nqi ntawm kev nyab xeeb ntawm qhov chaw siab mus rau qhov muaj peev xwm tsawg.Cold-shrinkable silicone roj hmab cov khoom muaj elasticity zoo.Ntev npaum li tus qauv tsim tsim nyog, nws lub zog muaj zog muaj peev xwm tuav tau txaus.Lub shrinkage kub ntawm lub tshav kub shrinkable cable taub hau yog 100 ℃ -140 ℃, thiab qhov kub yuav ua tau raws li nws cov shrinkage tej yam kev mob tsuas yog thaum nws yog ntsia.Thaum qhov kub thiab txias tsis tshua muaj, vim tias qhov thermal expansion coefficient ntawm lub cable txawv ntawm cov khoom siv cua sov-shrinkable, nws muaj peev xwm tag nrho cov delamination yuav tshwm sim hauv ib puag ncig qis dua 80 ℃, yog li cov kab nrib pleb yuav tshwm sim.Nyob rau hauv txoj kev no, dej thiab noo noo yuav nkag mus rau hauv qhov kev txiav txim ntawm kev ua pa, yog li rhuav tshem cov rwb thaiv tsev ntawm lub cev.Txawm li cas los xij, thaum ib puag ncig hloov pauv, tsis muaj elasticity zoo li silicone roj hmab, yog li nws tseem yuav cuam tshuam rau kev nyab xeeb.Qhov no yog qhov tsis zoo ntawm cov khoom siv cua sov shrinkable.
Hluav taws xob Field
Cov hluav taws xob hluav taws xob ntawm cov kab mob khaub thuas-shrinkable cable yog kho los ntawm geometric txoj kev, uas hloov cov hluav taws xob xa hluav taws xob los ntawm lub cone kev ntxhov siab.Nws yog daws nrog ib tug tej yam geometric duab thiab ib tug meej R lub.Txoj kev no yooj yim dua los tswj thiab sim.Nws tuaj yeem ua kom ntseeg tau thiab ua tiav hauv lub Hoobkas.Txoj kev kho hluav taws xob hauv hluav taws xob ntawm lub tshav kub shrinkable cable lub taub hau yog hloov cov hluav taws xob xa hluav taws xob los ntawm txoj kev linear parameter.Nws yuav tsum cia siab rau ob qhov tseem ceeb: lub ntim tsis kam, 108-11Ω, thiab b dielectric tas li ntawm 25. Vim nws cov txheej txheem ntau lawm thiab cov kev hloov loj vim yog ib puag ncig, nws yog ib qho nyuaj rau tswj kev ruaj ntseg ntawm cov tsis.Yog li ntawd, nws yuav muaj kev cuam tshuam rau qhov zoo ntawm cov khoom.
Xaiv qhov zoo tshaj plaws cable txiav los yog cov pob qij txha rau qhov project yuav tsum tsis txhob twv.Koj qhov kev txiav tawm cable sai sai yuav dhau los ua ib feem tseem ceeb ntawm koj txoj haujlwm.Koj tsis tuaj yeem them taus ib feem ntawm kev lag luam uas raug kaw vim muaj kev kho ntau zaus lossis kev puas tsuaj.Txoj cai txias shrink / tshav kub shrink cable txiav cov khoom yuav ua rau koj cov khoom tsim tau thiab ua kom yooj yim dua rau cov neeg ua haujlwm.Tsuas yog xyuas kom tseeb tias koj ua qhov kev tshawb fawb kom tsim nyog los xaiv qhov kev txiav tawm cable uas ua haujlwm tag nrho koj txoj haujlwm, muab kev pabcuam txhim khu kev qha, thiab koj cov neeg ua haujlwm raug cob qhia kom raug.
