Background

The coil angle ring is mainly applied to the insulation of the coil end of the transformer, and the final use form of the coil angle ring is a full-circle closed state. The current way to manufacture the angle ring is: low-density paperboard forming and wet paper blank hot press forming. The two modes are influenced by the die, the product is made in a multi-section split mode, and a plurality of lap joints exist in the actual use of the product. Due to the overlapping factor, when the product is used, certain gaps exist in the axial direction and the plane direction of the coil end part, so that the size of an oil passage is not uniform, and the electrical stability of the transformer is influenced.
