Abstract
A tubular article has an outer component of insulating material having a convoluted outer surface, and an inner component of stress grading material. In another embodiment, a tubular article has an outer component of insulating material having an outer surface that is convoluted along part of its length and shedded along another part of its length. The articles may be of heat-shrinkable polymeric material. The articles are particularly useful for terminating high voltage electric cables, and in the manufacture of electrical insulators.
