Product Description

Specifications
1, 35kV, S11, 3 phase oil immersion power transformer
2, high efficiency, low loss
3, Low losses and Low Noise
Describtation of the product:
The three-phase oil-immersed distributing transformer applies new type insulating structure and makes short-circuit resistances strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent them from losening.
