A by-pass device, adapted to be connected between lengths of cable through which fluid is being passed and electric current is being conducted, and a piece of electrical equipment through which the electric current is to be connected, which permits the fluid being conveyed to by-pass the piece of electrical equipment includes: a first member and a second member, each of the members being fittings composed of an electricity-and-fluid passage section adapted to be connected to a cable; an electricity passage section adapted to be connected to a piece of electrical equipment; and a fluid conveying section adapted to convey fluid in a divergent path away from the current of electricity; and a conduit connecting each of the fluid conveying sections so as to permit the fluid flow between the fluid conveying sections of each member to by-pass the electrical device without interrupting the circuit of electric current. A method for flushing cables connected to electrical equipment with fluid in a manner which permits the fluid passing through the cables to by-pass the electrical apparatus while permitting the electricity conducted by the cable to pass into and through the electrical equipment in an uninterrupted fashion throughout a cable system.

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.
