Studies of bondable magnet wire

The thermosetting adhesive appears to reduce the thermal life by about 10 to 15°C, However, the thermal life on the basis of 40,000 hours, which the Navy uses for thermal rating varnished samples shows the rating to be greater than 160°C for the heavy build base coat magnet wires. The voltage stress on the single build wires (samples 5 and 6) was the same as that used for the heavy build wires (1 through 4). Therefore the thermal rating of samples 5 and 6 would be less.
