Crosslinked polyethylene insulated fais fab cable yog dav siv nyob rau hauv lub zog system vim nws cov thermal thiab mechanical zog, zoo heev hluav taws xob zog thiab tshuaj corrosion kuj. Nws kuj muaj qhov zoo ntawm cov qauv yooj yim, lub teeb yuag, nteg tsis txwv los ntawm kev poob, thiab yog siv dav hauv nroog fais fab, mines, tshuaj nroj tsuag thiab lwm yam scenes. Kev rwb thaiv tsev ntawm cable sivcross-linked polyethylene, uas yog chemically hloov los ntawm linear molecular polyethylene mus rau hauv ib tug peb-dimensional network qauv, yog li zoo heev txhim kho lub mechanical zog ntawm polyethylene thaum tuav nws zoo heev hluav taws xob zog. Cov nram qab no qhia txog qhov sib txawv thiab qhov zoo ntawm crosslinked polyethylene insulated cables thiab zoo tib yam insulated cables los ntawm ntau yam.
1. Cov khoom sib txawv
(1) Kub tiv taus
Qhov ntsuas kub ntawm cov kab hluav taws xob zoo tib yam feem ntau yog 70 ° C, thaum qhov ntsuas kub ntawm cov kab txuas txuas txuas polyethylene insulated cables tuaj yeem ncav cuag 90 ° C lossis siab dua, txhim kho cov cua sov ntawm cov cable, ua rau nws haum rau qhov chaw ua haujlwm hnyav dua.
(2) Lub peev xwm nqa tau
Nyob rau hauv tib cheeb tsam tus neeg xyuas pib hla ntu, lub peev xwm nqa ntawm XLPE insulated cable tam sim no yog siab dua li ntawm cov kab hluav taws xob zoo tib yam, uas tuaj yeem ua tau raws li cov khoom siv hluav taws xob nrog cov kev cai loj tam sim no.
(3) Scope ntawm daim ntawv thov
Cov kab hluav taws xob zoo sib xws yuav tso cov pa luam yeeb HCl thaum kub hnyiab, thiab tsis tuaj yeem siv rau hauv cov xwm txheej uas xav tau kev tiv thaiv hluav taws kub thiab tsis muaj tshuaj lom. Tus ntoo khaub lig-txuas polyethylene insulated cable tsis muaj halogen, ntau tus phooj ywg ib puag ncig, tsim nyog rau kev sib koom tes, kev teeb tsa kev lag luam thiab lwm yam xwm txheej uas yuav tsum tau muaj hluav taws xob loj, tshwj xeeb tshaj yog AC 50Hz, ntsuas voltage 6kV ~ 35kV tsau nteg xaim xaim thiab xaim kab.
(4) Tshuaj stability
Crosslinked polyethylene muaj cov tshuaj tiv thaiv zoo thiab tuaj yeem ua haujlwm zoo hauv ib puag ncig ntawm cov kua qaub, alkalis thiab lwm yam tshuaj, uas ua rau nws tsim nyog rau kev siv tshwj xeeb xws li cov nroj tsuag tshuaj thiab Marine ib puag ncig.
2. Qhov zoo ntawm cross-linked polyethylene insulated cable
(1) Thaum tshav kub kub tsis kam
Crosslinked polyethylene yog hloov los ntawm tshuaj lom neeg los yog lub cev txhais tau tias los hloov cov qauv linear molecular mus rau hauv peb-dimensional network qauv, uas zoo heev txhim kho cov tshav kub tsis kam ntawm cov khoom. Piv rau cov khoom siv hluav taws xob zoo tib yam thiab polyvinyl chloride rwb thaiv tsev, crosslinked polyethylene cables muaj kev ruaj khov dua nyob rau hauv qhov kub thiab txias.
(2) Kev ua haujlwm siab dua
Tus neeg xyuas pib qhov ntsuas kub ntawm kev ua haujlwm tuaj yeem ncav cuag 90 ° C, uas yog siab dua li cov tsoos PVC los yog polyethylene insulated cables, yog li txhim kho cov cable tam sim no muaj peev xwm thiab kev ua haujlwm ntev.
(3) Superior mechanical zog
Lub crosslinked polyethylene insulated cable tseem muaj cov khoom siv thermo-mechanical zoo ntawm qhov kub thiab txias, kev ua haujlwm zoo thaum tshav kub kub, thiab tuaj yeem tswj tau cov neeg kho tshuab ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig ntev.
(4) Lub teeb yuag, yooj yim installation
Qhov hnyav ntawm tus ntoo khaub lig-txuas polyethylene insulated cable yog sib dua li ntawm cov kab hluav taws xob zoo tib yam, thiab kev tso tsis yog txwv los ntawm kev poob. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov chaw tsim kho complex thiab loj-scale cable installation scenarios.
(5) Kev ua haujlwm zoo ib puag ncig:
Cov kab txuas txuas nrog polyethylene insulated cable tsis muaj halogen, tsis tso cov pa roj carbon monoxide thaum lub sij hawm combustion, tsis tshua muaj kev cuam tshuam rau ib puag ncig, thiab tshwj xeeb tshaj yog haum rau cov chaw uas yuav tsum nruj rau kev tiv thaiv ib puag ncig.
3. Qhov zoo ntawm kev teeb tsa thiab kev saib xyuas
(1) Ntau dua durability
Crosslinked polyethylene insulated cable muaj ntau dua los tiv thaiv kev laus, haum rau lub sij hawm ntev faus nteg los yog raug rau sab nraum zoov ib puag ncig, txo qhov zaus ntawm kev hloov cable.
(2) Muaj zog rwb thaiv tsev kev ntseeg tau
Qhov zoo tshaj plaws rwb thaiv tsev ntawm crosslinked polyethylene, nrog high voltage kuj thiab tawg lub zog, txo txoj kev pheej hmoo ntawm rwb thaiv tsev tsis ua hauj lwm nyob rau hauv high voltage daim ntaub ntawv.
(3) Cov nqi kho mob qis dua
Vim muaj kev tiv thaiv corrosion thiab kev laus tiv thaiv ntawm crosslinked polyethylene insulated cables, lawv cov kev pab cuam lub neej ntev dua, txo cov txij nkawm txhua hnub thiab hloov cov nqi.
4. Qhov zoo ntawm kev txhawb nqa tshiab
Nyob rau hauv xyoo tas los no, nrog kev txhim kho ntawm crosslinked polyethylene khoom siv tshuab, nws cov rwb thaiv tsev kev ua tau zoo thiab lub cev muaj zog tau raug txhim kho ntxiv, xws li:
Txhim kho cov nplaim hluav taws, tuaj yeem ua tau raws li cov chaw tshwj xeeb (xws li subway, chaw nres tsheb fais fab) hluav taws kub;
Txhim kho qhov txias tsis kam, tseem ruaj khov nyob rau hauv qhov chaw txias heev;
Los ntawm cov txheej txheem crosslinking tshiab, cov txheej txheem tsim khoom siv hluav taws xob muaj txiaj ntsig zoo dua thiab zoo ib puag ncig.
Nrog nws cov kev ua tau zoo heev, cross-linked polyethylene insulated cables nyob hauv txoj haujlwm tseem ceeb hauv kev xa hluav taws xob thiab kev xa tawm, muab kev nyab xeeb dua, txhim khu kev qha thiab ib puag ncig kev xaiv rau cov phiaj xwm niaj hnub hauv nroog thiab kev tsim kho kev lag luam.
