●The 20kV class three-phase double-winding non-excitation voltage regulating distribution transformer adopts the type of S13-M series fully sealed oil-immersed transformer, without oil conservator, moisture absorber and other devices, ensuring that the transformer oil does not contact with air and delaying the aging of transformer oil. The coil adopts a layer structure, with uniform ampere-turn distribution and reasonable insulation structure, which has strong short-circuit impact resistance. A corrugated oil tank is used, and the corrugated fins can expand and contract with the expansion and contraction of the transformer oil, so as to maintain a certain pressure inside the transformer and enhance the reliability of operation.
●Suitable for power plants, substations (distribution stations), and industrial, commercial, construction and other fields.
●Implement national standards such as GB1094 and GB6451.
