I-110kV INQANABA LESITHATHU SESIGABA SESITHATHU UKUTSHINTSHWA KOMLAYIZO-TEP
ISITSHINTSHI SAMANDLA OMBANE
Isishwankathelo
Siye samkela uthotho lohlaziyo olubalulekileyo kumgangatho we-110kV wesigaba sesithathu se-oyile entywiliselwa kumthwalo wemathiriyeli yokutshintsha impompo,
inkqubo kunye nesakhiwo.I-transformer ineempawu zobukhulu obuncinci, ubunzima obulula, ukusebenza kakuhle okuphezulu, ilahleko ephantsi, ingxolo ephantsi, ukusebenza okuthembekileyo njl.
enokunciphisa isixa esikhulu selahleko yothungelwano lwamandla kunye neendleko zokusebenza ngeenzuzo ezibalulekileyo zezoqoqosho.Ifanelekile kwisikhululo sombane,
icandelo elinzima amashishini ore ore njl.
