Product Advantage
  1. Using high permeability silicon steel sheets and a cylindrical structure with copper foil wrapped around the shaft, the no-load loss is reduced by 30% compared to traditional models, and the load loss is reduced by 20%.

  2. Adopting high-purity oxygen free copper wire coils, with a local discharge capacity of less than 10PC, the coils have moisture-proof and dust-proof characteristics, and the mechanical strength reaches the industry-leading level.

  3. Choose high-quality insulating oil and use vacuum oil filtration and oil injection processes for better insulation and stronger short-circuit resistance.
