  • a consideration for high voltage cable design is that there are often hot spots along part of the high voltage cable route. Therefore, the entire high voltage cable is designed according to the worst conditions that occur along the high voltage cable route. This would normally mean that the diameter of the entire cable had to be dimensioned based on the worst conditions, resulting in over- dimensioning of the cable, and high costs associated therewith.

Copper for example has a higher conductivity than aluminium, and a copper section may thus be utilised along a portion of the high voltage cable which would otherwise require a larger diameter aluminium section.
