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 19/33kV Manufacturer’s Name Description of Cable.
For example, for a 1-core, 240 mm2, XLPE insulated cable, the legend would read as follows:
ZESCO Ltd, Electric Cable 19/33kV Manufacturer’s Name 1x240mm2 XLPE/AWA/PE
NOTE: The bedding material is not included in the XLPE/AWA/PE naming convention.
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
