Resin-rich Class H coil passes the test

PREFORMED WINDINGS HAS invested over 12,000 hours of research and development into collaboration with leading OEM’s and insulation manufacturers over the past three years. The result is the launch of the QualCoil H range of resin rich coils that are said to offer low Partial Discharge (PD) levels.

QualCoil H has been independently tested and has successfully achieved over 2,000 hours on Voltage Endurance (VE) testing at 28kV at a temperature of 120°C without failure. Voltage endurance testing is designed to simulate the typical life of a motor or generator and the pass criteria for the test carried out on QualCoil H was 400 hours, which demonstrates the potential benefits to end users. Motors and generators will be able to operate for longer, will be more efficient and will require less maintenance.
