1. Abubuwan kayan aiki da sigogi
Mai amfani: Aiki a Macau
● Ajiyayyen wutar lantarki: UPS + 6000kVA janareta
Jimlar ƙarfin gaggawa: 4500kVA, 3600kW
Tsarin wutar lantarki: Babban ƙarfin lantarki 11kV, 50Hz da ƙananan ƙarfin lantarki 415 Vac50Hz
Ikon: 4 KTA50-GS8 samfura / 1200kW janareta saiti
Saitin janareta: babban 3 da madadin 1, tare da 1 an tanada don kulawa.Ana iya haɗa kowane saitin janareta zuwa grid ɗin wuta don amfani
Saitin janareta: 415Vac/lokaci uku/50 hawan keke
● Ƙarƙashin allon wutar lantarki na saitin janareta:
5000A busbar / 80kA1 seconds / uku-lokaci hudu waya / 50 hawan keke
An raba bas ɗin 5000A zuwa sassan A da B
Sashin A na mashigar motar yana haɗe zuwa saitin janareta guda biyu, ɗaya da biyu
