CTC Global ACCC® Conductor presented at Leitungsbau

The annual Leitungsbau event held at EKZ Dietikon presents the Swiss TSO and DSO community with the opportunity to share experiences on network developments through a series of presentations and associated Q&As. Whilst operating a separate network with its own generation, SBB (the Swiss Railway) also operates a significant network at different voltages and frequencies.

The Swiss population is especially sensitive to any network developments, particularly overhead lines, and EMF emission levels are the lowest in Europe. This, coupled with a public preference to use underground cables wherever possible, presents Swissgrid and the other operators with particular challenges in network expansion.

With overhead line emissions regulated, the size of any overhead conductor is limited and pathways tend to be very tight over undulating territory. It was perhaps with this background that, for the 2019 Leitungsbau event, CTC Global was tasked by the organizing committee of Electrosuisse to present an overview of modern conductor technologies, including ACCC® Conductors.

During the presentation, CTC Global used its CCP™ (Conductor Comparison Program) software to demonstrate the temperature and current-carrying capacity of various conductor types which would be compliant with the Swiss regulations.

“Our comparisons on capacity increase and sag reduction stimulated considerable interest,” stated Peter Hughes, CTC Global’s VP for North Europe after the event. “This was the first time composite technologies were presented to the Swiss audience at a national level and modern conductors clearly have a role to play in future network developments.”
