    It has been more than thirty years since high molecular weight polyethylene (HMWPE) was first introduced as a commercial insulating material for medium voltage (15-35 kV) underground residential distribution (URD) cables. That began a dramatic expansion of utility electrical service that has led to the installation of several million miles of URD cables by over 3,000 utility companies across Ameri...

    During the past seven years, over 2.5 million feet of cable in North America and Europe have been treated using silicone dielectric enhancement technology. Most of the treated cable has been rated at 10-25kV and most has been small residential distribution cable. The anecdotal results from the field implementation are impressive. Virtually all failures have halted in the treated URD cables. Early ... View full abstract»

    The use of furnace process carbon blacks in semiconductive shields for cable is well known. For medium- to high-voltage power cables, furnace carbon black-filled semiconducting materials are used most notably to prevent a partial discharge at the surface between the conductor and the insulation or the insulation and the insulation shield layers. The author shows that two critical carbon black prop... View full abstract»
