5000 kVAuku fase kushin saka transformerAn isar da shi zuwa Amurka a cikin 2025. Ƙarfin ƙarfin wutar lantarki shine 5000 kVA tare da sanyaya ONAN. Babban ƙarfin lantarki shine 33GrdY/19.053kV tare da kewayon tapping ± 2*2.5% (NLTC), ƙarfin lantarki na biyu shine 0.48Y/0.277kV, sun kafa ƙungiyar vector na YNyn0.

Na'urar canza wutar lantarki da ake amfani da ita sosai a tsarin rarraba birane da karkara. Babban aikinsa shi ne musanya babban{3}}lantarki mai ƙarfi zuwa ƙaramar wutar lantarki, ba da damar samar da lafiya ga masu amfani da kasuwanci, masana'antu, da mazauna. The pad Dutsen transformers kunshi rufaffiyar tanki bakin karfe tsara don jure yanayi daban-daban. Akwatin ya ƙunshi na'ura mai canzawa, na'urori masu sauyawa, kayan kariya, da sauran abubuwan da ake buƙata na lantarki. Ƙirƙirar kushin lokaci guda uku- - da aka ɗora tasfoma ya ƙunshi matakan tsaro da yawa, gami da kariyar wuce gona da iri, gajeriyar kariyar kewayawa, da tsarin ƙasa don tabbatar da amintaccen aiki da kulawa.
