Product Overview
This series of oil-immersed transformers breaks through the traditional planar structure and adopts a three-phase symmetrical three-dimensional structure.
The magnetic circuits of the three-phase iron cores are completely symmetrical, which greatly reduces magnetic resistance and significantly lowers exciting current and no-load loss.
It is an energy-efficient transformer that uses traditional materials while achieving lower operating noise and a more compact overall structure.
The design delivers strong performance in energy conservation, consumption reduction, material saving, and environmental protection.
