Nta

1. Thaum tshav kub kub kuj: XLPE nrog net-zoo li peb-dimensional qauv muaj zoo heev kub kuj.Nws yuav tsis decompose thiab carbonize hauv qab 300 ° C, lub sijhawm ua haujlwm kub tuaj yeem ncav cuag 90 ° C, thiab lub neej thermal tuaj yeem ncav cuag 40 xyoo.

2. Rwb thaiv tsev kev ua tau zoo: XLPE tswj cov khoom qub zoo ntawm PE, thiab cov rwb thaiv tsev kuj nce ntxiv.Nws cov dielectric poob tangent yog me me thiab tsis cuam tshuam los ntawm qhov kub thiab txias.

3. Cov khoom siv kho tshuab: Vim yog tsim cov tshuaj sib txuas tshiab ntawm macromolecules, hardness, txhav, hnav tsis kam thiab kev cuam tshuam ntawm XLPE yog tag nrho cov kev txhim kho, yog li ua rau qhov tsis zoo ntawm PE uas muaj kev cuam tshuam rau ib puag ncig kev ntxhov siab thiab tawg.

4. Tshuaj tiv thaiv: XLPE muaj zog acid thiab alkali tsis kam thiab roj tsis kam, thiab nws cov khoom combustion feem ntau yog dej thiab carbon dioxide, uas tsis tshua muaj teeb meem rau ib puag ncig thiab ua tau raws li cov kev cai ntawm kev nyab xeeb hluav taws niaj hnub no.

110kV XLPE insulated fais fab cable nta muaj txiaj ntsig zoo ntawm lub teeb qauv, siab siv nruab nrab, tsis tshua muaj qhov nruab nrab, ruaj hauv kev laus, yooj yim rau kev teeb tsa, nteg tsis txwv lub caij nplooj zeeg thiab lwm yam. tshwj xeeb.Daim ntawv thov ntawm qhov no ntawm cable nyob rau hauv underground municipal transforming thiab kis kab yog nce.
