Intambo egqunywe nge-XLPE luhlobo lwentambo efanelekileyo kwinethiwekhi yokusasazwa nakwezinye iindawo, enezibonelelo ezingenakuthelekiswa nanto zentambo egqunywe nge-PVC. Inesakhiwo esilula, ubunzima obulula, ukumelana nobushushu okuhle, amandla omthwalo aqinileyo, ukunganyibiliki, ukumelana nokugqwala kweekhemikhali kunye namandla aphezulu oomatshini.
1. Ukumelana nobushushu: I-XLPE enesakhiwo esifana ne-net-like three-dimensional inokumelana nobushushu okugqwesileyo. Ayiyi kubola kwaye i-carbonize ngaphantsi kwe-300°C, ubushushu bokusebenza bexesha elide bunokufikelela kwi-90°C, kwaye ubomi bobushushu bunokufikelela kwiminyaka engama-40.
2. Ukusebenza kwe-insulation: I-XLPE igcina iipropati ezilungileyo ze-insulation ze-PE, kwaye ukumelana ne-insulation kuyanda ngakumbi. I-tangent yayo yokulahleka kwe-dielectric incinci kakhulu kwaye ayichaphazeleki kakhulu bubushushu.
3. Iimpawu ze-mechanical: Ngenxa yokusekwa kweebhondi ezintsha zeekhemikhali phakathi kwee-macromolecules, ubulukhuni, ukuqina, ukumelana nokuguguleka kunye nokumelana nempembelelo ye-XLPE konke kuyaphucuka, ngaloo ndlela kulungisa iintsilelo ze-PE ezichaphazeleka kuxinzelelo lokusingqongileyo kunye neentanda.
4. Ukumelana neekhemikhali: I-XLPE inokumelana okunamandla kwe-asidi kunye ne-alkali kunye nokumelana neoyile, kwaye iimveliso zayo zokutsha ikakhulu ngamanzi kunye ne-carbon dioxide, engonakalisi kangako okusingqongileyo kwaye ihlangabezana neemfuno zokhuseleko lomlilo lwanamhlanje.
