      Product Application

      S(Z)11 and S(Z)11-M series oilimmersed transformers produced by the company are a new generation of energy-saving products, widely used in the power system of 10kV and below lines, for transmission, transformation, distribution, power stations, power, lighting, and high-voltage/low-voltage prefabricated substations.

      Model and Its Meaning

      Product features

      1.Adopting corrugated or plate type radiator oiltank, with a beautiful appearance.
      2.The use of a new hanging plate structure has solved the problem of the body being suspended.
      3.Transformer oil does not come into contact with the atmosphere, so it is not necesary to conduct regular oil sample tests (sealed).
      4.Equipped with self-locking anti loosening nuts, adopting a non hanging core structure, the body is closely matched with the oil tank, and can withstand transportation vibrations and bumps.
      5.Ripple plates not only have coling function, but also have "breathing'function, and their elasticity can compensate for the oil volume changes caused by temperature changes.
      6.During the normal lifespan, there is no need to change oil, which improves the safety and reliability of power grid operation.
