Power Transmission Cable Systems
We have experience of working with ESOs, TSOs and power contractors across the UK and Ireland, delivering matched power transmission cable systems to help mitigate risks in power transmission.
Understanding your market
We understand the complexities of project engineering in power transmission and we’ve built a team with a proven track record of delivering successful projects. We share your vision for a safe, resilient and flexible energy network, adapting to change in power markets through innovation and technical expertise.
Unlocking potential in power transmission
Power transmission is key to delivering electricity from where it’s generated to where it’s used, which is vital to support economic growth and social progress. As power sectors continue to evolve, reliable transmission networks ensure energy security, lower costs, and facilitate the integration of renewable energy sources.
High voltage and extra high voltage cables are essential in power transmission. High voltages are used to minimise energy loss as the power is transmitted over long distances.
Experts in power transmission cable solutions
Our solutions include 132kV, 275kV and 400kV HV/EHV cables, matched to a wide range of components and accessories to ensure the most appropriate systems for installation. Our experience covers fossil fuels and renewables, across overhead, underground and offshore power transmission.
Market-leading power transmission cables
A carefully-selected range of best-in-class cables held in stock, including Low Voltage 1kV//3kV, Medium Voltage 33kV, High Voltage 132kV and Extra High Voltage 275kV/400kV.
