  • Apparatus and method for prolonging the service life of electrical power cables
    Patent number: 4545133
    Abstract: A method and apparatus for retarding electrochemical type decomposition of electrical insulation by flushing moisture from the insulation of installed power cables with a fluid having a low moisture content. The insulation of the power cables is dried and maintained dry by a continuous flow of dry fluid through the conductor and insulation while the cable is energized. An apparatus is disclosed which provides for the fluid to enter and exit from the cable. The disclosed method provides an effective retardation of the growth of electrochemical trees in the insulation structure and thereby significantly extends the useful life of the cable system.
