PCT No. PCT/SE93/00944 Sec. 371 Date May 8, 1995 Sec. 102(e) Date May 8, 1995 PCT Filed Nov. 9, 1993 PCT Pub. No. WO94/11887 PCT Pub. Date May 26, 1995A multi-core cable (15) for communicating electric power and electrical signals to and from a hand held power nutrunner (10). Three longitudinal sections (16-18) are arranged in parallel with each other, and each has a geometric center (20-22) such that in any cross section of the cable (15) the geometric centers (20-22) are disposed on a straight line (24). A flex zone (A) is arranged adjacent the nutrunner (10) and has a preformed longitudinally twisted shape for obtaining a universal flexibility of the cable (15) and, thereby, a comfortable handling of the nutrunner (10). |
