Construction Features  

The primary and secondary coils are wound using special winding and  shielding techniques for improved voltage stress distribution. Each coil   is carefully insulated with mylar film to provide a high dielectric medium  between layers. The completed winding structure and double-loop cores  are assembled to a support frame.  For insulation and protection, the assembly is cast in hydrophobic  cycloaliphatic epoxy (HCEP) using automatic pressure gelation. The  HCEP material offers superior arc track, ozone, and ultraviolet-resistive  properties while maintaining physical strength. The hydrophobic surface  properties of HCEP ensure highly reliable performance in wet, humid,   or polluted environments.
