product description
Feature of Three-Dimensional Coil Core Oil-immersed Transformer
This series of oil-immersed transformers breaks through the traditional planar structure and adopts a three-phase symmetrical three-dimensional structure. The magnetic circuit of the three-phase iron core is completely symmetrical, the magnetic resistance is greatly reduced, and the excitation current and no-load loss are significantly decreased. It is an energy-efficient transformers that use traditional materials but have lower noise and more compact. Its outstanding performance in energy conservation and environmental protection is completely compliance with China's energy conservation policy. This series of products are suitable for 10KV power saving projects such as urban power grid, rural power grid, factories, schools and so on.
