Thumela i-imeyiliIzintambo zikagesi ze-XLPE ezifakwe i-XLPE ezingama-6.35-11kV zifanelekela amanethiwekhi okusabalalisa noma okwesibili okudlulisa, ngokuvamile zisebenza njengomthombo wamandla oyinhloko wamanethiwekhi ezindawo zokuhlala zezentengiselwano, zezimboni, kanye nezasemadolobheni. Zisebenza ezinhlelweni ezinezinkamba zamaphutha aphezulu ezilinganiselwa ku-10kA/1 umzuzwana. Izakhiwo zezinkamba zamaphutha aphezulu ziyatholakala uma ziceliwe. Zifanele ukusetshenziswa okungaguquki emhlabathini, ngaphakathi/ngaphandle, emigudwini yekhebula, ngaphansi kwamanzi, nalapho izintambo zingabhekene nokucindezeleka okukhulu komshini noma ukucindezeleka kokudonsa. Ngenxa yesici sayo sokulahlekelwa yi-dielectric esiphansi kakhulu, esihlala singaguquki kuyo yonke impilo yayo yokusebenza, kanye nezakhiwo zokuvikela eziphakeme zezinto ze-XLPE, le ntambo ibonisa ukuthembeka okuphezulu kokusebenza. Isivikelo somqhubi kanye nokufakwa kwezinto ze-semiconductor kuhlanganiswe ngokuphephile ubude obude (i-extrusion ye-single-pass). Zifanelekela iziteshi ezincane, iziteshi zikagesi, kanye nezitshalo zezimboni.
I-HV Cable Insulation XLPE inezinzuzo ezilandelayo:
1. Ukusebenza Kokumelana Nokushisa:
I-XLPE enesakhiwo esinezinhlangothi ezintathu esihlanganisiwe inokusebenza okuhle kakhulu kokumelana nokushisa. Ngeke ibole futhi ifake i-carbon ngaphansi kwama-300℃, izinga lokushisa lokusebenza lesikhathi eside lingafinyelela kuma-90℃, futhi impilo yokushisa ingafinyelela eminyakeni engama-40.
2. Ukusebenza Kokuvimbela:
I-XLPE igcina izici zokuqala zokuvikela ezinhle ze-PE, futhi ukumelana nokuvikela kuyanda kakhulu.
Inani layo le-dielectric loss angle tangent lincane kakhulu, futhi alithinteki kakhulu yizinga lokushisa.
3. Izakhiwo Zomshini:
Ngenxa yokusungulwa kwezibopho zamakhemikhali ezintsha phakathi kwama-macromolecule, ubulukhuni, ukuqina, ukumelana nokuklwebheka, kanye nokumelana nomthelela kwe-XLPE kuye kwathuthukiswa, ngaleyo ndlela kwalungisa ukushiyeka kwe-PE okusengozini yokucindezeleka kwemvelo kanye nokuqhekeka.
4. Izici Zokumelana 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.
Ukwakhiwa:
Ukwakhiwa:I-triplex enomgogodla owodwa, oyinhloko emithathu, enomgogodla ongu-3×1.
Umqhubi:Ithusi noma i-aluminium, iyindilinga evalekile, iyindilinga encane evalekile.
Ukuvikela:I-XLPE noma i-TR-XLPE noma i-EPR.
Ukuvikela insimbi:Isivikelo sentambo yethusi, isivikelo setheyiphu yethusi.
Isigqoko:Isivikelo se-alloy ye-lead, isivikelo se-aluminium esigoqekile, isivikelo sethusi esigoqekile.
Ukuvikela:Ukuvikela izintambo ze-aluminium (AWA), ukuvikela izintambo zensimbi (SWA), ukuvikela izintambo zensimbi engagqwali (SSWA).
Ibanga Lokushisa:
Izinga lokushisa eliphansi lokufakwa: 0°C
Izinga lokushisa eliphezulu lokusebenza: +90°C
Izinga lokushisa eliphansi lokusebenza: -25°C
