Thumela i-imeyiliIzintambo zikagesi ezivikelwe nge-12.7-22kV-XLPE ezivalekile zivame ukusetshenziswa kumanethiwekhi okusabalalisa amandla kanye nezintambo zikagesi ezisizayo ezindaweni ezahlukahlukene. Ukuzivikela okuhlanganisiwe kuvumela ukungcwaba okuqondile ukuvimbela ukushaqeka kukagesi ngengozi kanye nomonakalo. Uhlobo lwe-AS/NZS 12.7-22kV-XLPE luhlanganisa izintambo zikagesi ezisebenza nge-voltage ephakathi ezakhiwe ngokwe-Australian/New Zealand Standard AS/NZS 1429.1. Zifanele ukufakwa okuqinile ngaphakathi kwamanethiwekhi okunikezwa kwamandla kokubili ezindaweni zangaphakathi nangaphandle, futhi zingafakwa emigudwini yekhebula, kumathreyi ekhebula, noma zingcwatshwe ngqo ngaphansi komhlaba. Zifanele izinhlelo zamandla kagesi aphezulu afinyelela ku-10kA/1 isekhondi. Izakhiwo ezinamakhono wamandla wamandla aphezulu atholakala uma ziceliwe.
Ukwakhiwa:
Umqhubi:Ithusi noma i-aluminium, iyindilinga evalekile, iyindilinga encane evalekile.
Ukuvikela:I-XLPE noma i-TR-XLPE noma i-EPR.
Ukuvikela insimbi:Ukuvikela ucingo lwethusi (CWS), ukuvikela itheyiphu yethusi (CTS).
Isigqoko:Isikhumba se-aluminium esine-corrugated (CAS), Isikhumba sethusi esine-corrugated (CCU), Insimbi engagqwali ene-corrugated (CSS).
Ukuvikela:Ukuvikela izintambo ze-aluminium (AWA), Ukuvikela izintambo zensimbi (SWA), Ukuvikela izintambo zensimbi engagqwali (SSWA).
Ukuvikelwa komuhlwa:Isikhwama se-nylon se-polyamide, i-Double brass tape (DBT), i-Cypermethrin.
Amakhebula okufaka:12D (i-PVC kuphela) 15D (i-HDPE).
Ngesikhathi sokufakwa:18D (i-PVC kuphela) 25D (i-HDPE).
Ububanzi bokushisa:
Izinga lokushisa eliphansi lokufakwa: 0°C
Izinga lokushisa eliphezulu lokusebenza: +90°C
Izinga lokushisa eliphansi lokusebenza: -25°C
Izintambo ze-Medium Voltage eziklanywe ngokwezifiso:
Ukuze isebenze kahle futhi ihlale isikhathi eside, yonke ikhebula le-MV kufanele ilungiselelwe ukufakwa kodwa kunezikhathi lapho kudingeka khona ikhebula elenziwe ngendlela efanele. Ochwepheshe bethu bekhebula le-MV bangasebenza nawe ukuklama ikhambi elifanela izidingo zakho. Ngokuvamile, ukwenza ngokwezifiso kuthinta usayizi wendawo yesikrini sensimbi, esingalungiswa ukuze kushintshwe umthamo we-short circuit kanye nemibandela yokufakwa komhlaba.
Kuzo zonke izimo, idatha yobuchwepheshe inikezwa ukuze kuboniswe ukufaneleka kanye nemininingwane ethuthukisiwe yokwenziwa. Zonke izixazululo ezenziwe ngokwezifiso zingaphansi kokuhlolwa okuthuthukisiwe eSikhungweni sethu Sokuhlola Ikhebula le-MV.
