ABSTRACT:
An armoured electric cable having integral tensile members to provide additional tensile strength. The tensile members are embedded in an inner PVC jacket which securely grips the central insulated conductors over which it is extruded. The jacket is, in turn, securely gripped by an armour cover formed of a steel strip which is wound helically around the jacket and bites into longitudinal ridges on the jacket. The armour coating has an undulating shape and is covered by an outer PVC jacket which is extruded over it. Thus, in the vertical position much of the weight of the insulated conductors, inner and outer PVC jackets and armour coating can be supported by the tensile members without producing dangerous longitudinal slippage or creepage between them.
