Abstract
Method for joining electrically and mechanically the multiple aluminum wires of a pair of electrical cable conductors in which the bared conductor ends are beveled and welded together and a metal sleeve, which is more rigid than the aluminum of the conductors, is applied around the weld and lengths of the conductors at each side of the weld and compressed until the sleeve has an outer size substantially equal to the size of the portions of the conductors at each side thereof. The sleeve has inner grooves for receiving displaced aluminum, and if the conductors have central channels, the channels are joined at the conductor ends by a relatively incompressible tube which fits into the channels and which may have peripheral grooves for receiving displaced aluminum. Also, a cable joint made by such method.
