Product Overview
  • Key Technical Advantages & Grid-Level Value
Its design prioritizes both efficiency and grid resilience: a high-magnetic-permeability silicon steel core minimizes hysteresis loss, while low-loss copper windings reduce current transmission waste—paired with an enhanced heat dissipation system (hybrid ONAN/ONAF cooling) that maintains optimal operating temperatures even under peak loads, resulting in industry-leading low loss and ultra-quiet performance (≤65dB at 1m). With an insulation rating of LI450AC200 and above, it delivers robust short-circuit withstand capacity, capable of withstanding transient current surges without damage—critical for preventing grid cascading failures. To adapt to dynamic grid conditions, it integrates on-load tap changers (OLTC) for real-time voltage adjustment and advanced online monitoring systems (tracking oil quality, winding temperature, and partial discharge). These features enable it to operate reliably in harsh outdoor environments (resisting extreme temperatures and humidity) and provide early warnings of potential issues, ensuring long-term safe and stable grid operation.
