D25 series high-efficiency, low-loss single-phase transformer is suitable for agricultural production, lighting & power consumption in rural power grid and remote mountainous areas. It can also be used for urban power grid transformation, providing excellent energy-saving effects. The transformer can be installed directly on the platform or on a wire pole. The combination of low voltage of the transformer is 2 * 0.23kv. Its low voltage current is only half compared to ordinary single-phase transformers. The biggest advantage is that line loss is only 1/4 (P=I²R) comparing the use of the former with the latter one, which is the main reason for international users' preference for this model.
