35-KV amorphous oil-immersed transformer high-voltage coils

The utility model relates to transformer high-voltage coils, in particular to 35-KV amorphous oil-immersed transformer high-voltage coils. The 35-KV amorphous oil-immersed transformer high-voltage coils are characterized in that the high-voltage coils have a sectional structure, with upper and lower portions being wound at the external of an outer corrugated cardboard; an inner corrugated cardboard is disposed at the inner side of the outer corrugated cardboard; the outer corrugated cardboard and the inner corrugated board form a main insulating channel between high/low voltage coils; and the upper and lower portions of the coils are serially connected and are wound in opposite directions. The 35-KV amorphous oil-immersed transformer high-voltage coils are small in volume and excellent in economy. Meanwhile, the 35-KV amorphous oil-immersed transformer high-voltage coils also allow a great decrease in interlayer insulating voltage, thereby achieving higher longitudinal insulating level and higher insulating s
