HiFLEX coil insulation system

With HiFLEX services at Houghton International:

  • Coils are fully tested at point of manufacture guaranteeing dielectric integrity.
  • Coils can then be step-down tested before being inserted and throughout the repair process.
  • Coils are fully cured but totally flexible in the end-winding (coil extension).
  • Requires no baking after winding.
  • Requires no VPI or impregnation.
  • Guaranteed storage life — the coils are fully cured so they cannot change state in storage.
  • Coils are supplied in a vacuum packed, moisture proof bag inside a heavy-duty wooden crate as standard.
  • Class F 155°C as standard > 6.6kV.
  • Allows total flexibility in its end-winding (coil extension), which can remain flexible for the machine’s cycle.
  • Guaranteed flexibility of the coils, which is ideal for large two-pole windings, rewinding in situ and for skewed alternator coils.
  • Only requires spray varnish to seal off outhangs.
