Best Paths new conductor car awarded Best Innovation at ICOLIM 2017

3 May 2017 - As the European grid infrastructure is ageing, innovative technological solutions for live maintenance and power lines’ upgrade will be needed in the coming years to refurbish the current electricity network. To address this challenge, Best Paths experts have been invited to present their novel solutions for live-line working and electricity grid’s refurbishment during a dedicated session at the ICOLIM 2017 (International Conference on Live Maintenance), held on 26 and 27 April in Strasbourg (France).


After a short opening speech from Bálint Nemeth, Manager of the Budapest High Voltage Laboratory and chairman of the session, Best Paths experts highlighted the innovation the project spurred in the fields of maintenance and power line refurbishment in front of over 80 professionals from the electricity sector, including researchers as well as representatives from Transmission System Operators and Distribution System Operators.


Among the solutions showcased, the new extra-light conductor car for live-line working - designed, constructed and tested by the the Budapest High Voltage Laboratory team -  sparked a lot of attention. The conductor was awarded Best Paper and Best Innovation during the gala dinner closing the conference.


German partners from the Safety of Structures Federal Institute for Materials Research and Testing, the Technische Universität Dresden and 50Hertz also presented the results of the ageing tests they conducted on High Temperature Low Sag conductors. In the future, this kind of conductors could replace aluminium conductor steel reinforced for the repowering of transmission overhead line corridors.


In addition, the Belgian electricity transmission system operator Elia featured the innovative insulated cross-arms made of composite insulators, which they have designed and installed. Best Paths Swedish partners ABB and STRI also had the chance to present their new testing method to provide optimal dimensioning of grading rings for composite insulators. This method  reduces the deterioration caused by water, which is one of the main ageing factors for transmissions grids. The last paper, presented by STRI, focused on the comparison of the results of the thermal rating methods I-line and Cigré TB 601.
