| Summary: | The increased demand for power transfer in
combination with environmental and economic issues which set
constraints to building new lines, force the implementation of new
technologies into the existing system in order to improve its
power capability. Such methods involve re-tensioning, re�conductoring, or modifying the tower design to utilize composite
cross-arms. It is hypothesized that a composite cross-arm and a
novel conductor together provide an insulating significant
opportunity to increase the overhead line voltage. The paper
explores the range of options that could be implemented on an L3
overhead line tower typically used at 275kV in the United
Kingdom, and demonstrates clear improvement in power
capacitiy through the implementation of new technologies. |
