High-tensile steel cores for overhead power lines

Steel has been utilized for decades in various markets, including the transmission market, due to its availability, strength, consistent performance, and recyclability. Our advanced steel cores leverage these properties, and the conductors made from them are designed to address numerous challenges directly.

By employing cutting-edge technology, we deliver solutions that improve the reliability and efficiency of overhead line conductors, ensuring they meet the stringent requirements of modern electricity transmission and distribution.

What's more, by using a steel core, no special installation procedures or equipment are required.

One such example is the reference project of an urban reconductoring project in Bratislava. Built by a Slovakian DSO, the existing towers—many of them decades old—had to remain in place while transmission capacity was increased. By combining advanced conductor design with ultra‑high‑strength steel strands, ageing infrastructure can be upgraded without complex reconstruction works. Projects like this show how less visible technologies, such as high‑performance steel cores, can play a very practical role in enabling the energy transition by making existing networks work more efficiently and reliably.
