Rudzi Rwakaoma: Rwakatonhodzwa nemhepo, rwakakodzera nzvimbo dziri mukati/dzinotsvedza nemoto (semuenzaniso, nzvimbo dzedata).
Gas-Insulated (GIS): SF6 gas insulation, dhizaini diki ye substations dzine density yakakura.
5. Rudzi rwekudzivirira
Mafuta Akanyudzwa: Mafuta emineral kana ester (asingakuvadzi nharaunda).
Rudzi Rwakaoma: Epoxy resin casting kana Nomex paper insulation (inodzivirira moto/kuputika).
Gas-Insulated: SF6 kana magasi akasanganiswa (zviteshi zvemagetsi zvine simba rakawanda).
6. Kushanda zvakanaka
Maitiro Akajairika:
MaTransformer Ekuparadzira: ≥98% (kurasikirwa kwakaderera kwemutoro uye kurasikirwa nemutoro).
MaPower Transformers: ≥99% (mamodheru emagetsi akakwira zvakanyanya anobudirira zvakanyanya).
Mitemo: Tevedzera IEC 61620 kana IEEE C57.12 (semuenzaniso, zvinodiwa neEU Ecodesign).
7. Boka reKubatanidza
Musiyano wePhase: Unozivikanwa seDyn11, Yd11, zvichiratidza hukama hwephase pakati pemawindings ekugadzirisa harmonics uye ma short-circuit currents.
8. Impedance Voltage
Tsanangudzo: Kudzikira kwepercentage voltage panguva yekuedzwa kwe short-circuit, zvichiratidza kugona kwe short-circuit kumira.
Maitiro Akajairika: 4–10% (matransformer emagetsi), ≤4% (matransformer ekuparadzira).
9. Kukwira kweTembiricha
Miganhu: Matransformer anonyudzwa mumafuta anowanzo bvumira kukwira kwetembiricha ye ≤55 K (mafuta epamusoro pa40°C).
Kujairana Nezvakatipoteredza: Nzvimbo dzerenje dzinoda kushatirwa kwakanyanya.
10. Kuongororwa kweDziviriro
Makodhi eIP:
IP23: Inopfapfaidzwa isina guruva, isingapindi mvura.
IP66/IP68: Yakavharwa zvizere kubva muguruva/mvura (kushandiswa kwemvura/kunze kwegungwa).
