The D11 series high-efficiency, low-loss single-phase transformer is ideal for agricultural production, lighting, and power consumption in rural grids and remote areas. It can be installed directly on platforms or wire poles. The low voltage current is only half compared to ordinary single-phase transformers, resulting in line losses of only 1/4 (P=I²R).
Key Feature: Oil-immersed transformers use oil as the main insulation and cooling medium. This design ensures low noise due to the buffer effect of the oil on silicon steel sheets.
