Abstract: A cable includes a filler (12) including a plurality of points of weakness (13) or discontinuities spaced along its length. The points of weakness or discontinuities may be evenly spaced along the length of the cable and may be formed by partially or fully cutting through the filler. The filler may be formed from a plastics material and may be shaped, in cross section, to have a number of arms to enable it to separate other components of the cable. The filler may be electrically conducive or semi-conductive to enable it to act as screen between other components of the cable.
