Rated capacity 30kVA~1 600 kVA Three-Phase Three-Dimensional Roll-Core Distribution Transformer
Three-dimensional roll-core distribution transformer is a kind of energy-saving power transformer. It creatively upgrades the laminated magnetic structure and three-phase layout of traditional power transformers, which optimizes the performance of transformers. The three-phase magnetic circuit is completely symmetric, with significant power-saving effect, greatly decreased noise, high heat dissipation performance, strong overload capacity, more compact structure and smaller volume.
