Cable Marking: The external surface of the cable shall be
legibly embossed with the following
information on two lines running parallel to
the length of the cable, approximately
equally spaced around the circumference of
the cable. Zesco Ltd, Electric Cable 6.35/11kV Manufacturer’s Name Description of Cable. For example, for a 3-core,185 mm2, XLPE insulated cable, the legend would read as follows: Zesco Ltd, Electric Cable 6.35/11kV Manufacturer’s Name 3x185mm2 XLPE/SWA/PE In addition, the cable shall be sequentially marked, by indelible printing, indenting or other suitable means, at 1 m intervals, to indicate the approximate length of cable remaining on the drum. The numbers shall start with 001, 1 m from the inner end of the cable and continue every metre to the outer end. The start and finish lengths of sequential markings (if not 0 to 400m) shall be indicated on the cable drum
