Ikhebula le-XLPE elivalekile

Ikhebula le-XLPE elivalekile liwuhlobo lwekhebula elifanele inethiwekhi yokusabalalisa nezinye izinkambu, ezinezinzuzo ezingenakuqhathaniswa zekhebula le-PVC elifakwe ngaphakathi.Inesakhiwo esilula, isisindo esilula, ukumelana nokushisa okuhle, umthamo oqinile womthwalo, ukungancibiliki, ukumelana nokugqwala kwamakhemikhali namandla aphezulu emishini.

1. Ukumelana nokushisa: I-XLPE enesakhiwo esinezinhlangothi ezintathu esifana nenethi inokumelana nokushisa okuhle kakhulu.Ngeke ibole futhi i-carbonize ngaphansi kuka-300 ° C, izinga lokushisa lesikhathi eside lingafinyelela ku-90 ° C, futhi impilo eshisayo ingafinyelela eminyakeni engu-40.

2. Ukusebenza kwe-insulation: I-XLPE igcina izakhiwo ezinhle zokuvikela ze-PE, futhi ukumelana nokushisa kuyanda.I-tangent yokulahlekelwa kwe-dielectric incane kakhulu futhi ayithinteki kakhulu izinga lokushisa.

3. Izakhiwo zemishini: Ngenxa yokusungulwa kwezibopho zamakhemikhali ezintsha phakathi kwama-macromolecules, ubulukhuni, ukuqina, ukumelana nokugqoka kanye nokumelana nomthelela we-XLPE konke kuthuthukisiwe, ngaleyo ndlela kwenzelwa ukushiyeka kwe-PE okungase kube lula ukucindezeleka kwemvelo nokuqhekeka.

4. Ukumelana namakhemikhali: I-XLPE inokumelana ne-asidi eqinile ne-alkali kanye nokumelana nowoyela, futhi imikhiqizo yayo evuthayo ngokuyinhloko ingamanzi ne-carbon dioxide, engeyona ingozi encane emvelweni futhi ihlangabezana nezidingo zokuphepha komlilo zanamuhla.

110kV XLPE ikhebula lamandla agqunyiwe linobuhle obuningi besakhiwo sokukhanya, ukuqina okuphezulu, ukulahlekelwa okumaphakathi okuphansi, okuhlala isikhathi eside ebudaleni, kulula ukufakwa, ukubeka ngaphandle komkhawulo wokuwa njll. Ikhebula lamandla kagesi elingu-110kV XLPE lingasetshenziswa ekudluliselweni kwamandla kagesi kanye nezintambo zokusabalalisa. ikakhulukazi.Ukusetshenziswa kwalolu hlobo lwekhebula emigwaqweni engaphansi komhlaba kamasipala eguqulayo kanye neyokudlulisa izintambo kuyakhula.

I-aluminium conductor	L	I-sheath ehlanganisiwe yensimbi nepulasitiki	A	Isakhiwo se-Longitudinal waterretardant	Z

Qaphela: Izigaba zeshethi ye-aluminium egoqiwe zifaka ishethi ye-aluminium egoqwe kanye neshethi ye-aluminium eshiselwe.Izimpawu zazo ziyafana ne-LW.Igobolondo le-aluminium elishiselwe ngokuqinisekile licaciswe egameni lomkhiqizo.Igama lesigaba elingenawo "okushiselwe" uhlobo lweshede ye-aluminium esongwe.
