The world’s electrical grids are under pressure. Decades-old infrastructure, rising urban power demands and the rapid expansion of data centers and electric vehicles are creating a widening gap between power supply and consumption. The need for fast, efficient and sustainable solutions has never been more urgent.

In this webinar, Heini Kloster, product manager for Conductor Cores, and John Mertic, sales manager at Exel Composites will explore how carbon fiber composite cores and reconductoring can help modernize transmission infrastructure — without starting from scratch. You will learn how this innovative technology enables high- temperature, low-sag (HTLS) performance, reduces energy losses and helps transmission system operators (TSOs) to increase capacity quickly by using existing powerline structures.

Exel will also explain the key differences between single-wire and multi-wire composite cores, and how Exel’s continuous pultrusion manufacturing and decades of composites experience ensures quality, flexibility and scalability for global infrastructure upgrades. Join this webinar to find out how reconductoring with composite cores can eliminate bottlenecks, cut costs and increase transmission capacity in a more sustainable, compliant and future-proof way.
