High and extra high voltage systems
The transmission of electricity in high voltage (HV: 36–150 kV) and extra-high voltage (EHV: 220–500 kV) networks is one of the most important technological challenges in the energy industry. This requires the use of the most advanced cable systems, which must guarantee reliability, safety and cost-effectiveness. Due to the key importance of these networks for the economy, HV and EHV systems are subject to detailed regulatory standards that ensure their long-term reliability and high quality over years of operation.

Application of HV and EWN cables
Cables designed for HV and EWN systems are mainly used in the transmission of electricity over long distances, especially in critical infrastructure, such as power plants, large industrial facilities or in regions where it is important to limit the impact of infrastructure on the natural environment. Their use allows the creation of underground installations, which helps to minimize the visibility of the network and reduce the impact on the landscape.
TELE-FONIKA Kable is one of the leaders in the production of HV and EWN cable systems, offering cables with cross-sections up to 3000 mm² and voltage up to 500 kV, characterized by high quality and reliability, which guarantees the continuity of energy supply in demanding conditions.
