1. A cable, comprising:
a plurality of strands twisted together at a cable pitch in the range of 5 mm to 7 mm,
each strand comprising a plurality of filaments twisted together at a strand pitch SP in the range of 2.9 mm≤ SP ≤5.9 mm, the plurality of filaments of each strand comprising
a single, central filament having a central filament diameter, and
a plurality of outer filaments wrapped around the central filament, each outer filament having an outer filament diameter, wherein the central filament diameter is greater than the outer filament diameter of each outer filament, and wherein adjacent outer filaments are in contact with each other along the length of the cable;
wherein a pitch ratio of the cable pitch CP to the strand pitch SP is in the range of 1.2≤ pitch ratio ≤1.7,
wherein the cable has a structural elongation of between 2.1 percent and 3 percent.
