    110kV IZINGA LESITHATHU LOKUSHINTSHA I-TAP-LAD

    I-ELECTRIC POWER TRANSFORM

    Isifinyezo

    Sesamukele uchungechunge lwezinguquko ezibalulekile ezingeni le-110kV lesigaba sesithathu se-oyela egxiliswa ku-tap-changing transformer material,
    inqubo kanye nesakhiwo.I-transformer inezici zosayizi omncane, isisindo esincane, ukusebenza kahle okuphezulu, ukulahlekelwa okuphansi, umsindo ophansi, ukusebenza okuthembekile njll,
    okunganciphisa inani elikhulu lokulahlekelwa kwenethiwekhi yamandla kanye nezindleko zokusebenza ngezinzuzo ezibalulekile zezomnotho.Ilungele indawo yokutshala amandla,
    amabhizinisi ensimbi yengxenye esindayo njll.
