IPS offers IntegraSeal™ B-stage hard coils for on-site rewinds of medium and high-voltage AC motors and generators, including steam turbine generators and hydroelectric generators. IntegraSeal™ represents the state of the art for high-voltage coils, combining industry-leading magnet wire and insulating materials with advanced technologies — precision automated manufacturing, automatic turn taping and digitally CNC controlled coil spreading — for significant improvements in dielectric and thermal performance.
IntegraSeal™ packs more power and reliability into your on-site electric motor and generator rewinds, increasing power density, reliability and efficiency in highly engineered applications and upgrading older motor or generator designs. Every IntegraSeal™ coil meets or exceeds independent third-party standards, including the IEEE 1043 voltage endurance test, IEEE Standards 522 and 286, ANSI Standards C-50-10 to C-50-26, and is certified to ISO Standard 9001:2008 with Design.
As part of our commitment to QA and lowering the cost of your maintenance engineering, we use EL CID (electromagnetic core imperfection detection) testing on all IPS on-site rewinds (EL CID is also part of our ongoing maintenance programs for extremely large motors and generators). We combine stator core diagnostics with a corona maintenance inspection, view recent and past partial discharge testing, and apply the appropriate resins to slow down partial discharge activity. This buys your maintenance department valuable time before the next planned outage — time we use to document our findings for future inspections and help you move toward increased uptime and lower maintenance costs.
