In a sodium cable the conductor is contained within a foil sheath having a bonded, overlapped seam and bonded to a layer of polymeric composition. Apparatus for making this cable includes a pipe for the sodium and a tube former forming a tube of foil-adhesive laminate around the pipe which extends into an extruder for applying the layer of polymeric composition. A method of making the sodium conductor cable comprises continuously forming a foil-laminate tube and filling it with sodium during the extrusion operation.
