The future of
Relibond is offering a novel and disruptive cable joining solution to the power transmission industry. Relibond technology is removing a 2-day manual cable procedure and converts it into a semi-automated solution dramatically reducing the process-time to less than 1 hour. We have succeeded to drastically reduce the cable handling time through novel thinking and an innovative approach using a combination of technologies never seen in the cable industry before.
Relibond technology accommodates future challenges introduced by the aging power transmission infrastructure, the rise of global electricity demand and the increasing electricity production from renewable energy sources. Commonality to the challenges is that power cables are increasing in size enabling them to meet future current-carrying capacity requirements. With increasing conductor size for AC systems a more complex low loss conductor is introduced (Milliken conductor) reducing the limiting skin- and proximity effects. However, the increasing conductor complexity dramatically increases the manual handling time for conductor preparation prior to testing and joining of conductors in production and at installation. Increasing manual handling time influences overall production and installation time as well as overall risk of costly cable failures.
ReliBond solution is enabling dramatically faster testing, production and installation of Milliken conductors for AC systems. Current preparation procedure consist of going through up to 600 individual wires in the conductor and manually removing insulation compounds such as varnish, oxide layers or water barriers prior to any connection or termination. Relibond technology is eliminating the necessity of the time-consuming removal of compounds. Conductor connection and termination can be carried out in less than an hour with Relibond technology. Preparation of a Milliken conductor prior connection can take 1 full day, hence resulting in a total additional time-consumption of 6 days per circuit per joint. Relibond technology will be reduce the preparation time to less than 3 hours.
Relibond technology can significantly reduce the time to answer when testing cable characteristics in production and at installation. In-line routine test of AC resistance, ongoing adjustments of material consumption and continues joining quality assurance are not performed today. With Relibond technology this would be possible without increasing production or installation time, thus resulting in minimizing overall risk of failure and optimized use of materials.
By using Relibond technology completely new opportunities arises for cable manufactures, installers and transmission system operators (TSO’s) in regard to new materials, tools and testing systems. Relibond technology is not only applicable for low loss conductors but can be used with any type of conductor where the features of the technology may be favourable. Opportunities within aluminium conductors and submarine cables are currently under investigation.
