George Bahder: Electrical cable joint structure and method of manufacture. Cable Technology Laboratories, Darby & Darby, December 11, 1984: US04487994 (23 worldwide citation)

A multilayer, heat shrinkable composite tube covering is provided for a cable joint structure in which intimately joined layers define a semiconductive inner or conductor shield, an insulation layer, and an outer or insulation shield for the joint. Furthermore, a highly resistive semiconducting laye ...
