From a winding shop to a global OEM
VOLTEDGE began as a coil-winding workshop in 1997. Three decades later we run automated core-cutting lines, vacuum vapor-phase drying and a 220kV screened test laboratory — yet the discipline remains the same: every transformer is treated as a 30-year promise to the grid it serves.
