Abstract
Abstract A sleeve joint for aluminum sheathed cable, particularly when jointing signal telephone and power cables, comprises an aluminum tube whose interior diameter is somewhat larger than the exterior diameter of the aluminum sheathed cable. Both ends of the tube are provided with slots forming a number of tongues which are deformable so that their extremities can be bent down to bear against the sheathed cable. The tongues and the continuous part of the tube are coated on their inside as well as their outside surfaces with a wiping solder consisting of lead, tin, zinc and antimony in special proportions.
