CIGRE 2020 – discussions about future power transmission systems

CIGRE 2020 digital e-session (August 24-September 3) has just come to an end. At the event, Prysmian Group experts provided insights and technical content during dedicated sessions.

CIGRE is a global organisation in the field of high-voltage electricity. It was founded in Paris, France, in 1921. The scope of its activities includes the technical and economic aspects of electrical grids, as well as their environmental and regulatory aspects.

During the sessions, experts discussed about how the latest developments can be applied to future power transmission systems, with solid perspectives on the lifecycle and environmental aspects of cables.

The Prysmian team was particularly lively, with 21 contributions from engineers and researchers who authored or co-authored 6 papers on several topics:

Innovative metallic sheaths for submarine cables allowing the replacement of lead sheaths, thus improving the environmental performance of the product and, at the same time, paving the way for HV dynamic cables
New armour design for deep water installation to lower the power loss of submarine cables systems and shorten the path from the development phase to the operation phase
Retrofitting solutions based on real scale mechanical and electrical tests to replace new cables in urban environments, minimizing disruptive works
Qualification of a tunnel installation, demonstrating the ability to satisfy severe installation conditions and to reduce the execution risks with testing protocols
Safety in maintenance works, with new protocols to verify the absence of voltage before starting repair works, ensuring even higher safety procedures
Safety in design and CPR regulation, showing the ability to propose a wide range of HV solutions with suitable fire performance
 

“E-sessions have been very much participated, with 47 papers presented and innovative technical content. The weeks of Study Committee B1 “Insulated cables” have been intense, with interesting future perspectives. Prysmian played a key role in the discussions, actively contributing to the development of the electrical system of the future.”
