Problems and Experiences with Polyethylene Jackets on Metal-Sheathed Cables

Objectives, test methods, results, and conclusions are detailed for four projects involving polyethylene protective jackets for underground high-voltage metal-sheathed cables. These projects involve: (1) evaluation of jacket materials, (2) the effect of fault currents on cable jackets, (3) the effect of switching surges on cable jackets, and (4) protection of joint housings in jacketed PILC (paper-insulated lead-covered) cable.
