ABSTRACT:
An insulated electrical member is made comprising at least one conductor wrapped with mica insulation and covered with a semiconducting binding tape, the whole being impregnated with a curable epoxy-styrene resin; where the binding tape comprises a porous, open weave substrate of electrically semiconducting fibrous strands, each fibrous strand being substantially permeated with a filled, thermosettable, protective varnish composition, the varnish composition containing between about 15 to 45 weight percent of electrically contacting carbon particles having a total internal and external surface area of up to about 600 square meters/gram, uniformly distributed therethrough, the interior of the carbon being substantially free of the varnish and resin, to provide fibrous strands that will conduct electricity.
