Bondable insulation systems

The bondable system concept provides a strong, uniform bond between all components of a motor, transformer or coil. Only two major components were changed when converting from a conventional insulation system to a bondable system. These components were: bondable magnet wire and "B" stage resin treated sheet and tape insulation. Bonding of the system may be accomplished by resistance or oven heating. When resistance heating, only the conductor is heated, activating the bond overcoat and "B" stage resins. Energy consumption is reduced to that required for bonding purposes. Compared to conventional methods, bondable systems require no varnish, dip tanks, pre-heat or curing ovens. Compliance with current environmental requirements is more easily met with these items no longer needed. Helical coil bond strength and moisture resistance are equal to or greater than most conventional dip and bake systems.
