From the supplier

This product adopts a segmented cylindrical structure for the cast coil, with short glass fiber as filler material. Axial air ducts are arranged inside the coil to improve heat dissipation conditions. The scientific casting and molding process ensures that resin fully penetrates between turns, layers, and sections, guaranteeing the product's electrical insulation strength and low partial discharge value (≤5 pC). How to prevent cracking of the resin casting body, control the generation of residual bubbles within the casting body, and minimize partial discharge to the extreme limit has always been a major challenge for dry-type transformer manufacturers worldwide, and represents the key manufacturing technology for resin-cast dry-type transformers. Through repeated production practices and extensive physicochemical experiments, our company has successfully solved this cutting-edge technical problem. As a result, our vacuum-cast products with short glass fiber filler and thin insulation achieve:
  • Tensile strength: increased to 170 N/mm²
  • Bending strength: increased to 220 N/mm²
This comprehensively enhances the mechanical properties of the cured resin solid.
