WINLEY manufactures cast coil transformers with capacity ratings of up to 10 MVA and voltage levels of 35 kV. Our factory is equipped with cutting-edge vacuum casting and production equipment. The epoxy resin dry transformers we design and produce meet or even exceed industry standards, including IEC 60076, ANSI/IEEE C57, and NEMA.

The cast coil transformer is a compact structure, low-noise, low-loss, moisture resistance, flame retardant, cast resin dry-type transformer. The high-voltage (HV) winding with copper conductors and the low-voltage (LV) winding with either copper conductors or copper sheet are wound and reinforced by glass-fiber and then cast with resin under vacuum.It is suitable for densely populated places and places with high environmental protection requirements, such as commercial centers, hospitals, schools, etc.
