Abstract
Stator bars for dynamoelectric machines are covered with an electrically conductive tape formed of a fabric support sheet carrying an electrically conductive polymeric binder system comprised of carbon particles dispersed in a polymeric matrix. The carbon particles are preferably selected from carbon black and/or graphite, and are present in the polymeric binder system in an amount of at least 5 percent by weight, based on the weight of the binder system. Low tip-up values of less than 0.025% and increased high voltage breakdown strengths of at least 700 VPM are obtained.
