The HydroCoil is custom engineered and employs advanced resin-rich tapes and processing methods for enhanced thermal cycling and improved dielectrics. The processing methods are optimized to increase ground wall density and ensure complete resin migration. The design and engineering combine to create a void-free coil, preventing delamination and any microvoids that can result in partial discharge activity and subsequent insulation deterioration. These fully cured and homogenized coils also prevent shrinkage, which means no re-wedging is required. The HydroCoil’s improved dielectrics and thermal dissipation means hydro generator rewinds can typically offer an increase in generator rating, permitting higher output power generation levels.

IEEE 1310 Thermal Cycling life test

IEEE 1043 Voltage Endurance life test

Industry-Leading Qualification TestingDuring testing for thermal cycling and thermal aging, the HydroCoil exhibited superior mechanical properties and thermal dissipation characteristics. The coils also exceeded all industry standards for voltage endurance testing. An independent 3rd party was used for verification testing, and the HydroCoil successfully completed the following tests:

• IEEE 1310 Thermal Cycling

» 500 Cycles X 90 minutes, 40˚C - 155˚C

• IEEE 1043 Voltage Endurance

» 400 Hours @ 30 kV

» 250 Hours @ 35 kV

• IEEE 1776-2008 Water Immersion at 15 kV

• IEEE 95 Hi Pot Test to 70 kV

• IEEE 286 Power Factor Tip Up

• IEEE 1434 Partial Discharge

• IEEE 522 Surge Test to 40 kV
