S-Series New Energy Chinese Type TransformerTransformer
The S-Series is a high-capacity (4000-10000 kVA) step-up transformer engineered for utility-scale photovoltaic and wind power plants. It efficiently converts generator-level low voltage to transmission-level high voltage (up to 40kV), facilitating efficient grid injection.
-
Engineered for renewable generation's variable loads, these transformers deliver high reliability and stability. Used as primary step-up units in wind/solar farms, they transmit power to grid substations via cable or overhead line.
