Izinga lokushisa eliphansi lokusebenza: -25 °C
Irediyasi encane yokugoba
Amakhebuli afakiwe: 12D (PVC kuphela) 15D (HDPE)
Ngesikhathi sokufakwa: 18D (PVC kuphela) 25D (HDPE)
Ukumelana Nokuchayeka Amakhemikhali: Ngengozi
Umthelela wemishini: Ukukhanya (PVC kuphela) Kunzima (HDPE)
Ukuchayeka emanzini: XLPE – Futha i-EPR – Ukucwiliswa/Ukufakwa kwesikhashana
Imisebe yelanga kanye nokuchayeka kwesimo sezulu: Ifanele ukuchayeka okuqondile.
Ukwakha:
Kwenziwe Nohlobo Oluhloliwe AS/NZS 1429.1, IEC: 60502-2 namanye amazinga asebenzayo
Ukwakheka - 1 core, 3 core, 3×1 core Triplex
I-Conductor - i-Cu noma i-AL, i-Stranded Circular, i-Stranded Compact Circular, i-Milliken ihlukaniswe
I-Insulation - i-XLPE noma i-TR-XLPE noma i-EPR
Isikrini se-Metallic noma i-sheath - Isikrini se-Copper Wire (CWS), isikrini se-Copper Tape (CTS), i-lead alloy sheath (LAS), i-Corrugated Aluminium sheath (CAS), i-Corrugated Copper sheath (CCU), i-Corrugated Stainless Stainless (CSS), i-Aluminium poly laminated (APL), Copper Poly Laminated (CPL), Aldrey wire screen (AWS)
Izikhali - Aluminium Wire Armored (AWA), Steel Wire Armored (SWA), Stainless Steel Wire Armored (SSWA)
I-polyethylene (i-HDPE) yangaphandle - okunye
Intuthu ephansi zero halogen (LSOH) - okunye
I-HV Cable Insulation XLPE inezinzuzo ezilandelayo:
1.Ukusebenza Kokumelana Nokushisa:
I-XLPE enesakhiwo esinezinhlangothi ezintathu esimisiwe inokusebenza okuhle kakhulu kokumelana nokushisa.Ngeke ibole futhi i-carbonize engaphansi kuka-300 ℃, izinga lokushisa lokusebenza lesikhathi eside lingafinyelela ku-90 ℃, futhi impilo eshisayo ingafinyelela eminyakeni engama-40.
2. Ukusebenza kwe-Insulation:
I-XLPE igcina izici ezinhle zokwahlukanisa ze-PE, futhi ukumelana nokufakwa kwe-insulation kuyanda.
I-dielectric loss angle tangent value incane kakhulu, futhi ayithinteki kakhulu izinga lokushisa.
3.Izakhiwo zikaMechanical:
Ngenxa yokusungulwa kwezibopho zamakhemikhali ezintsha phakathi kwama-macromolecules, ubulukhuni, ukuqina, ukumelana nokuhuzuka, kanye nokumelana nomthelela we-XLPE kuye kwathuthukiswa, ngaleyo ndlela kwenzelwa ukushiyeka kwe-PE okungenwa kalula ukucindezeleka kwemvelo nokuqhekeka.
4.Izici Zokuphikisa Amakhemikhali:
I-XLPE ine-asidi eqinile ne-alkali ukumelana nokumelana nowoyela, futhi imikhiqizo yayo evuthayo ikakhulukazi amanzi ne-carbon dioxide, engeyona ingozi emvelweni futhi ehlangabezana nezidingo zokuphepha komlilo zanamuhla.
