s11-630kva Oil-immersed TransformerS11/S13 series oil immersed distribution transformers use insulating oil as cooling and insulating medium. The core is made of high quality cold rolled sillcon steel, the oil tank adopts corrugated oil tank without oil conservaor. Vacuum oil injection process is adopted to effectively prevent oxygen and water from penetrating into transformer oilresulting in the decline of insulating oil performance. It is a new generation of energy-saving and environmental protection products.Type Ratedvoltage (kV) Winding connection mode Loss(W) Short-circuit impendance (%)...
