Design & Manufacturing Capabilities

  • DWV: proven designs up to 48kV between windings
  • Corona: proven designs up to 10kV AC between windings
  • Manufacturing practices developed and proceduralized to achieve corona-free product:
  • Rounded solder joints and tactical lead placement in order to minimize risk of arcing
  • Adequate margins between windings and insulation
  • Insulation protection between windings and over connections
  • Unique materials experience to achieve high operating temperatures, dissipation and dielectric
  • Encapsulation material and hardeners
  • Liquid and layer insulation types
  • Specific filler materials selected for reducing CTEs, improving temperature attributes and electrical strength
  • Vacuum Impregnation & Pressure Curing
  • Developed in-house equipment in order to varnish encapsulate under vacuum to ensure corona-free product
  • Custom procedures developed for vacuum or pressure curing to ensure void-free product
  • Vacuum drawn as low as 0.1 Torr; selectively chosen pressures for certain varnishes used
  • Custom molding materials and capabilities to protect design from environment and provide ability to assimilate design to a custom defined space (shape of final product)
