ABSTRACT:
A method of encapsulating electrical apparatus in a particulate filler material which is cohesively bonded together by a binder material which forms beads around the points of contact between contiguous particles. The filler material includes uncoated and dry, resin-coated particles, with the dry resin being redistributed after the particles of filler are in position about the electrical apparatus by the step of liquifying the resin coating with a liquid solvent, to form beads around the points of contact between contiguous particles.
