Power cable with corrugated metal mantle, plastics coating and sheath - has polyester-impregnated tape with pulling means lengthwise embedded in plastics layer

摘要

Electric cable is composed of a core, a corrugated metal mantle, an anti-corrosion plastics coating, and an outer-most sheathing. An axially parallel tensile tape with longitudinally extending pulling means is embedded in the plastics anti-corrosion coating. The tape is spaced away from the corrugated mantel. The pulling means are non-metallic glass or plastics threads filaments or yarns. The tape is water-impermeable and thermally stable. It may be impregnated with a plastics with similar characteristics, specifically a polyester.
