A system for the underground distribution of electrical power is provided and includes an electrical cable construction particularly adapted for use underground; and, the cable construction has a central conductor, a tubular insulator system for the conductor, a dual-purpose sacrificial anode supported by the insulator system and extending along substantially the full length of such insulator system, and a concentric neutral conductor supported by the insulator system and engaging the anode at a plurality of points therealong, with the dual-purpose sacrificial anode protecting the concentric neutral conductor against galvanic and soil corrosion as well as reducing AC corrosion of the concentric neutral conductor by providing additional surface area for the dissipation of currents leaving the neutral conductor.
An underground AC electrical power cable construction having an uncovered neutral conductor and an integral sacrificial anode protecting the neutral conductor, said cable construction also comprising a central conductor and tubular insulator means for said central conductor, said sacrificial anode being supported by said insulator means and extending along substantially the full length thereof, said neutral conductor being supported by said insulator means concentrically therearound and engaging said sacrificial anode at a plurality of points therealong, said sacrificial anode protecting said neutral conductor underground against soil and galvanic corrosion as well as reducing AC corrosion of said neutral conductor by providing additional surface area for the dissipation of currents leaving the neutral conductor.
A system for the underground distribution of AC electrical power comprising, a power source, a consumer tie-in station, and an underground AC power cable construction having one end portion operatively connected to said power source and having on an opposite end portion operatively connected to said tie-in station, said cable construction having an uncovered neutral conductor and an integral sacrificial anode protecting the neutral conductor, said cable construction also comprising a central conductor and tubular insulator means for said central conductor, said sacrificial anode being supported by said insulator means and extending along substantially the full length thereof, said neutral conductor being supported by said insulator means concentrically therearound and engaging said sacrificial anode at a plurality of points therealong, said sacrificial anode protecting said neutral conductor underground against soil and galvanic corrosion as well as reducing AC corrosion of said neutral conductor by providing additional surface area for the dissipation of currents leaving the neutral conductor.
