Product Details

The 3D wound-core transformer is an energy-efficient power transformer that innovatively redesigns the traditional laminated magnetic circuit structure and three-phase layout. This results in optimized performance, including perfectly balanced three-phase magnetic circuits, significant energy savings, greatly reduced noise, superior heat dissipation and overload capabilities, and a compact, space-saving design.

Product Features

Balanced Magnetic Circuits

The three-phase magnetic circuits of the 3D wound core are equal in length and minimized, ensuring balance across the three phases.

Excellent Energy Efficiency

The 3D wound core is seamless, eliminating high-energy-loss zones and fully utilizing the high magnetic permeability of the core material. The direction of magnetic flux aligns perfectly with the grain orientation of the silicon steel sheets, drastically reducing no-load losses and no-load current.

Low Noise

The silicon steel strips within each core frame are tightly wound, and the three frames are bonded into a solid, integrated structure. The magnetic permeability direction of the strips aligns perfectly with the magnetic circuit path. With minimal operational vibration and a closed-loop core structure free of air gaps, noise levels are minimized to the greatest extent possible.

High Short-Circuit Resistance

The transformer windings feature a circular cross-section, offering high compressive strength during short-circuit events. The clamping structure consists of a welded, triangular integrated frame, ensuring high stability and robust overall structural integrity.

Low Electric and Magnetic Field Intensity

The compact, symmetrical coil structure of the 3D wound core reduces stray magnetic fields surrounding the transformer.
