The 35kV three-phase oil-immersed distribution transformer adopts an advanced insulation design to enhance its short-circuit resistance. Its iron core is constructed with high-quality cold-rolled silicon steel, while the high-voltage windings are made from oxygen-free copper and arranged in a multilayered drum-type structure. All mechanical fasteners are specially treated to ensure stability and reliability during long-term operation.
As a high-tech energy-efficient product promoted at the national level, this transformer delivers excellent performance with high efficiency and low energy loss. Its implementation significantly reduces electricity consumption and operational costs, making it an ideal solution for modern power distribution systems.
