Abstract
Abstract A flexible power cable includes three current carrying conductors and three further stranding elements arranged in the corner spaces twisted about a profiled core which contains a steel cable as the support member of the cable. The profiled core includes a round strand containing a steel cable and of three profiled strands radially adjacent thereto, each of which can contain a support member and/or an electric conductor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
In a flexible power cable with conductors twisted about a profiled core, in which the profiled core contains a steel cable as a support member for the cable, the improvement comprising: a profiled core which includes a round strand containing a steel cable and three profiled strands disposed radially thereto adjacent, the cross section of said adjacent profiled strands shaped as a regular rectangle with circularly inwardly curved lateral edges; three current carrying conductors received in said inwardly curved lateral edges of said adjacent strands, said conductors forming, with said strands, at the outer ends of said adjacent strands, a total of three corner spaces one between each two current carrying conductors; and three further stranding elements arranged in the three corner spaces.
Claim 2
Dependent Claim
