Ikhebula elifakwe i-XLPE elifakwe i-insulation liwuhlobo lwekhebula elifanele inethiwekhi yokusabalalisa kanye neminye imikhakha, elinezinzuzo ezingenakuqhathaniswa zekhebula elifakwe i-insulation le-PVC. Linesakhiwo esilula, isisindo esincane, ukumelana nokushisa okuhle, umthamo oqinile womthwalo, ukungancibiliki, ukumelana nokugqwala kwamakhemikhali kanye namandla aphezulu omshini.
1. Ukumelana nokushisa: I-XLPE enesakhiwo esifana ne-net esinezinhlangothi ezintathu inokumelana nokushisa okuhle kakhulu. Ngeke ibole futhi ifake i-carbon ngaphansi kwama-300°C, izinga lokushisa lokusebenza lesikhathi eside lingafinyelela kuma-90°C, futhi impilo yokushisa ingafinyelela eminyakeni engama-40.
2. Ukusebenza kokuvikela: I-XLPE igcina izakhiwo zokuqala zokuvikela ezinhle ze-PE, futhi ukumelana kokuvikela kuyanda kakhulu. I-tangent yayo yokulahlekelwa yi-dielectric incane kakhulu futhi ayithinteki kakhulu yizinga lokushisa.
3. Izakhiwo zemishini: Ngenxa yokusungulwa kwezibopho zamakhemikhali ezintsha phakathi kwama-macromolecule, ubulukhuni, ukuqina, ukumelana nokuguguleka kanye nokumelana nomthelela kwe-XLPE konke kuyathuthuka, ngaleyo ndlela kulungisa ukushiyeka kwe-PE okuthinteka kakhulu yingcindezi yemvelo kanye nemifantu.
4. Ukumelana namakhemikhali: I-XLPE inokumelana okunamandla kwe-asidi kanye ne-alkali kanye nokumelana namafutha, futhi imikhiqizo yayo yokusha ikakhulukazi amanzi kanye ne-carbon dioxide, okungalimazi kakhulu imvelo futhi kuhlangabezana nezidingo zokuphepha emlilweni zanamuhla.
