Product Narrative
Application fit, product overview, key features, and selection value are presented in one product narrative.
Product Positioning
This three-dimensional wound core transformer is an energy-saving distribution transformer for distribution, wind, and photovoltaic applications that require both efficiency improvement and low-noise performance.
Product Overview
It uses conventional cold-rolled silicon steel but arranges the magnetic circuit in a three-dimensional layout so that the high-permeability direction of the strip aligns with the magnetic path. The three core legs form an equilateral triangular structure with equal magnetic-path length in all phases.
Product Features
- Average no-load loss reduced by about 30% compared with S11 products of the same capacity.
- No-load current reduced by about 70%.
- Noise reduced by about 10~25dB.
- Better material utilization and stronger short-circuit resistance.
Typical Scenarios
It fits projects that care about energy savings, noise control, and long-term operating stability, especially where advanced magnetic-circuit design is a selection factor.
Business Value
The three-dimensional wound-core structure improves energy performance and noise control at the same time, helping reduce overall operating cost and improve project efficiency metrics.
