Sealed cable and method of manufacturing

Abstract From the Canadian patent

An improved sheathed cable and method for producing same is described. The cable includes an inner insulated conductor/ conductor group, an outer corrugated metal sheath and a barrier, layer of a pliable, inert sealing material disposed therebetween to prevent the passage of gas or vapors via the cable. The method includes the steps of applying the pliable material around the inner insulated conductor/conductor group wrapping the, pliable material with a flexible tape forming an outer metallic, sheath around the material and making annular corrugations in, the outer sheath so as to compress the sealing compound.
