[0003] For example, a new type of simple and adjustable high-voltage coil winding mold for a dry-type transformer with a publication number of CN102945751A comprises two major parts: an aluminum end plate and an insulating cylinder made of a composite polyester film material. The end plate is symmetrically provided with stepped grooves of different depths along the circumference, and two bosses are symmetrically processed at both ends of the insulating cylinder. When the coil is wound, the bosses are fitted and embedded in the stepped grooves of the end plate. Different grooves on the end plate can be selected according to the capacity of the transformer and the size of the insulating cylinder to achieve the effect of changing the inner diameter of the coil.
