IPS WindGuard™ — The new IPS Class H rewind with a 60-year log life aging curve

Our new rewind has the dielectric and mechanical strength to prevent the problems that cause premature generator failures. IPS engineers addressed specific failure modes with this next generation insulation system:

  • Inter-turn insulation failures associated with high dv/dt transients
  • Ground wall failures associated with high cycle fatigue
  • Thermal aging associated with rapid thermal cycling and harmonics
  • Mechanical failures associated with continuous-duty cycle ramps

WindGuard combines the dielectric strength of PowerSeal® VPI mica tapes with the additional surge resistance of polyimide film, applied directly to the conductors using an advanced polymerization process for unsurpassed surge protection. This unique combination lets the rewind withstand the high-voltage transients and high-duty cycles associated with wind turbine generators.

The ability to maintain flexibility with zero thermal aging during rapid thermal cycling makes WindGuard the most robust insulation system offered to the wind power industry.

IPS WindGuard Coil

WindGuard tests like a high-voltage rewind and comes with a five-year warranty.
