High Efficiency Low Loss Transformer
3D Wound Core Transformer adopts triangular symmetrical silicon steel core,features balanced three phase flux,lower no load loss and ultra low noise.Ideal for urban residential,municipal grid,distributed PV,data center and industrial power projects.Middle East EU Southeast Asia market available.
Basic Info.
Our 3D Wound Core Transformer uses high grade grain oriented silicon steel and triangular 3D wound core structure. The three phase core forms a fully closed symmetrical magnetic path without overlapping lamination joints, which effectively reduces magnetizing loss, vibration and running noise.
Typical Applications
· Urban residential communities, hospitals, schools and commercial complexes
· Distributed photovoltaic systems and solar package substations
· Data centers and critical power supply systems
· Industrial plants, cold storage and mining facilities
· Municipal power grid renovation and rural electrification
· Rail transit and public infrastructure power distribution
