Single Core Copper XLPE Cable

The single core XLPE cable shown below in fig.1 was used as the standard circuit cable for 33kV up until March 2011. It is still available for repairs or deviations to existing Cu. cables, but has now been replaced by an aluminium version.
The cables in figs. 2,3 & 4 are used on windfarm and connection from the grid applications.
All single core 33 & 11kV cables should be laid in touching trefoil (triangular) formation and tied together.
