Re conductoring overhead lines to increase their capacity can often be intrusive, requiring new structures, and as such may be less viable than installing the equivalent (but more expensive) cable circuit. This project is consolidating techniques for maintaining existing line routes and structures but providing greater ratings.
The project aims to address the following objectives:

  • Novel conductors for 33kV lines as well as 132kV lines

  • Re tensioning and minor modifications to structures

  • Review of operating regimes (such as post fault regimes).
