Our experience showed inherent electrical failures occurred inside the slot of VPI machines, leaving a life expectancy of roughly 5 – 6 years, however, resin rich systems acted in reverse. The life expectancy was longer, but the failures occurred in the outhang (coil extension) rather than inside the slot.

HiBRID comprises a hot-pressed resin rich cell, scarfed into a VPI accepting outhang (coil extension), providing:

• Guaranteed slot fill
• World leading tan delta figures
• Excellent flexibility
• All coils are fully testable prior to varnishing
