XLPE insulated cable yog ib hom cable uas tsim nyog rau kev faib khoom network thiab lwm yam teb, uas muaj qhov zoo tshaj plaws ntawm PVC insulated cable. Nws muaj cov qauv yooj yim, lub teeb yuag, zoo tiv taus kub, muaj peev xwm thauj khoom tau zoo, tsis yaj, tiv taus tshuaj lom neeg corrosion thiab lub zog kho tshuab siab.
1. Kev tiv taus kub: XLPE nrog cov qauv peb-seem zoo li lub vas muaj kev tiv taus kub zoo heev. Nws yuav tsis lwj thiab carbonize hauv qab 300 ° C, qhov kub ua haujlwm ntev tuaj yeem ncav cuag 90 ° C, thiab lub neej thermal tuaj yeem ncav cuag 40 xyoo.
2. Kev ua tau zoo ntawm kev rwb thaiv tsev: XLPE tswj tau cov khoom rwb thaiv tsev zoo li qub ntawm PE, thiab qhov kev tiv thaiv rwb thaiv tsev ntxiv zuj zus. Nws qhov dielectric poob tangent me heev thiab tsis 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 tawv, kev hnav tsis kam thiab kev cuam tshuam ntawm XLPE tau zoo dua, yog li ua rau cov qhov tsis zoo ntawm PE uas yooj yim rau kev ntxhov siab thiab tawg.
4. Kev tiv thaiv tshuaj lom neeg: XLPE muaj zog tiv thaiv acid 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.
