Xa Ib Tsab EmailCov xov hluav taws xob nruab nrab 6.35-11kV XLPE-insulated yog tsim rau kev faib khoom lossis kev sib kis thib ob, feem ntau ua haujlwm ua lub zog tseem ceeb rau cov lag luam, kev lag luam, thiab cov nroog hauv nroog. Lawv siv tau rau cov kab ke uas muaj cov hluav taws xob siab txog li 10kA/1 vib nas this. Cov qauv rau cov hluav taws xob siab dua muaj thaum thov. Haum rau kev siv static hauv av, sab hauv tsev/sab nraum zoov, cov kav dej cable, hauv qab dej, thiab qhov twg cov cables tsis raug kev ntxhov siab loj lossis kev ntxhov siab tensile. Vim nws qhov dielectric poob factor qis heev, uas tseem ruaj khov thoob plaws nws lub neej kev pabcuam, thiab cov khoom siv insulating zoo dua ntawm XLPE, cov xov hluav taws xob no qhia txog kev ua haujlwm zoo. Cov ntaub thaiv conductor thiab cov khoom siv semiconductor rwb thaiv tsev tau ruaj ntseg longitudinally spliced (ib-pass extrusion). Haum rau substations, chaw fais fab, thiab cov nroj tsuag kev lag luam.
HV Cable Insulation XLPE muaj cov txiaj ntsig zoo li nram no:
1. Kev Ua Haujlwm Tiv Thaiv Kub:
XLPE nrog cov qauv peb-seem reticulated muaj kev ua tau zoo heev tiv taus cua sov. Nws yuav tsis lwj thiab carbonize hauv qab 300 ℃, qhov kub ua haujlwm ntev tuaj yeem ncav cuag 90 ℃, thiab lub neej thermal tuaj yeem ncav cuag 40 xyoo.
2. Kev Ua Haujlwm Rwb Thaiv Tsev:
XLPE tswj tau cov yam ntxwv zoo ntawm PE, thiab qhov tsis kam ntawm rwb thaiv tsev kuj nce ntxiv.
Nws lub dielectric poob lub kaum sab xis tangent tus nqi yog me heev, thiab nws tsis raug cuam tshuam los ntawm qhov kub thiab txias.
3. Cov Khoom Siv Kho Tshuab:
Vim yog kev tsim cov tshuaj sib txuas tshiab ntawm cov macromolecules, qhov nyuaj, kev sib zog, kev tiv thaiv kev sib txhuam, thiab kev cuam tshuam ntawm XLPE tau zoo dua, yog li ua rau muaj qhov tsis zoo ntawm PE uas yooj yim rau kev ntxhov siab ntawm ib puag ncig thiab tawg.
4. Cov yam ntxwv ntawm kev tiv thaiv tshuaj lom neeg:
XLPE muaj zog tiv taus kua qaub thiab alkali thiab roj, thiab nws cov khoom siv combustion feem ntau yog dej thiab carbon dioxide, uas tsis muaj teeb meem rau ib puag ncig thiab ua tau raws li qhov yuav tsum tau ua ntawm kev nyab xeeb hluav taws niaj hnub.
Kev Tsim Kho:
Kev Tsim Kho:Ib leeg-core, peb-core, 3 × 1-core triplex.
Tus Neeg Coj:Tooj liab los yog txhuas, txoj hlua khi puag ncig, txoj hlua khi compact puag ncig.
Kev rwb thaiv tsev:XLPE los yog TR-XLPE los yog EPR.
Kev tiv thaiv hlau:Kev tiv thaiv hlau tooj liab, daim kab xev tiv thaiv tooj liab.
Lub hnab tshos:Cov hlau txhuas ua lub plhaub, cov hlau corrugated aluminium, cov hlau tooj liab corrugated.
Kev Ua Riam Phom:Cov hlau txhuas tiv thaiv (AWA), hlau tiv thaiv hlau (SWA), hlau tsis xeb tiv thaiv hlau (SSWA).
Kub thiab txias:
Qhov kub tsawg kawg nkaus rau kev teeb tsa: 0 ° C
Qhov kub siab tshaj plaws ua haujlwm: + 90 ° C
Qhov kub ua haujlwm tsawg kawg nkaus: -25 ° C
