about structural sensitivity and integrity as their flexibility is comparable to the traditional ACSR. For many TSOs, this makes them a more favorable solution.”
Turning to the future, Heini shares her thoughts on what’ s next for Exel and the wider sector.“ We’ re constantly developing our products and production processes to meet the industry’ s evolving requirements, and we’ re actively working with different communities shaping the future of the transmission industry, such as CIGRE and IEC,” she says.“ In May, we’ ll be presenting a technical paper at CIGRE symposium in Trondheim, Norway, for instance, where we describe a study that showcases the reliability of the multi-wire core. The topic was proposed by Belgian TSO, Elia, and we conducted the study with De Angeli to show what happens inside a multi-wire core if an individual strand gets damaged or broken.
“ Interest towards composite core conductors is growing in different regions, and as more TSOs are starting to prototype these products, more experience is gathered and shared between them, making these solutions more attractive and adaptable. I firmly believe that pultrusion is the best way to produce conductor cores, which are needed in long lengths and uniform quality. Pultrusion processes love these kinds of products as that’ s when they get to highlight their advantages, so I see Exel’ s expertise in this method, combined with global production capacity, being a key attribute in supplier decisions.
“ In five years’ time, I’ d also like to see the industry guiding IEC standardization from technical specification to a verified standard, as that would be a welcomed addition to the tool kit of comparing different composite core solutions,” Heini concludes.“ The industry has rapidly evolved in recent years, so I expect us to have several lines up and running over the next few years.” ■
