Italian cable innovator Tratos Group has signed a four-year framework agreement with Finland-based Exel Composites Plc for the supply of high-performance carbon-fibre composite conductor cores, securing a minimum 22 million euro supply commitment through 2029. These advanced composites, integral to next-generation overhead transmission conductors, deliver higher tensile strength, lower thermal expansion, and superior high-temperature, low-sag performance compared with conventional steel cores, enabling utilities to boost line capacity, enhance transmission efficiency, and modernise grids without changing existing tower infrastructure.
This strategic agreement strengthens Tratos' long-term conductor programmes and ensures secure access to advanced composite core technology, supporting customers in the modernisation and upgrading of electricity transmission networks worldwide.
Composite conductor cores are a key enabler of the energy transition. Compared with traditional steel-reinforced designs, carbon-fibre composite cores offer higher tensile strength, lower thermal expansion, high-temperature low-sag performance, corrosion resistance and non-magnetic properties. These characteristics allow network operators to increase line capacity and transmission efficiency, often using existing towers and routes.
By integrating Exel Composites' continuously manufactured, quality-controlled composite cores into its overhead line conductor portfolio, Tratos further enhances its ability to deliver high-performance, reliable and sustainable solutions for grid upgrades and new infrastructure projects.
This agreement reflects Tratos' ongoing commitment to innovation, industrial partnerships and long-term planning, ensuring continuity of supply and technical excellence for its customers as investment in power grids accelerates across Europe and globally.
