Chingwe chotetezedwa ndi kutentha cha XLPE ndi mtundu wa chingwe choyenera kugwiritsidwa ntchito pa netiweki yogawa ndi zina, chomwe chili ndi ubwino wosayerekezeka wa chingwe chotetezedwa ndi PVC. Chili ndi kapangidwe kosavuta, kulemera kopepuka, kukana kutentha bwino, mphamvu yonyamula katundu mwamphamvu, chosasungunuka, kukana dzimbiri kwa mankhwala komanso mphamvu yayikulu yamakina.
1. Kukana kutentha: XLPE yokhala ndi kapangidwe kake kofanana ndi ukonde ka miyeso itatu imakhala ndi kukana kutentha kwambiri. Siidzawola ndi kupangitsa mpweya kukhala woipa pansi pa 300°C, kutentha kwa nthawi yayitali kumatha kufika 90°C, ndipo nthawi yogwira ntchito yotentha imatha kufika zaka 40.
2. Kugwira ntchito kwa chitetezo chamthupi: XLPE imasunga mphamvu zabwino zotetezera kutentha za PE, ndipo kukana kwa chitetezo chamthupi kumawonjezeka. Kutayika kwa dielectric tangent yake ndi kochepa kwambiri ndipo sikukhudzidwa kwambiri ndi kutentha.
3. Kapangidwe ka makina: Chifukwa cha kukhazikitsidwa kwa ma bond atsopano a mankhwala pakati pa ma macromolecules, kuuma, kuuma, kukana kuvala ndi kukana mphamvu kwa XLPE zonse zimakula, motero zimakwaniritsa zofooka za PE zomwe zimakhudzidwa ndi kupsinjika kwa chilengedwe ndi ming'alu.
4. Kukana mankhwala: XLPE ili ndi kukana kwamphamvu kwa asidi ndi alkali komanso mafuta, ndipo zinthu zomwe zimayaka makamaka ndi madzi ndi carbon dioxide, zomwe siziwononga chilengedwe ndipo zimakwaniritsa zofunikira za chitetezo chamakono pamoto.
