High & extra high voltage systems

High & extra high voltage systems

Transmission of electricity in high voltage networks (HV: UN 36-150 kV) and extra high voltage (EHV: 220-500 kV) has always been the biggest challenge, requiring the application of the most advanced technological solutions. Due to their nature and importance for the economy, the particularly restrictive requirements for trouble-free and economical operation are imposed on HV and EHV transmission networks.

These requirements are and were the driving force behind the changes in the technology of production of cables, setting new trends and standards on the market. The breakthrough involved the use of cross-linked polyethylene (XLPE) as cable insulation. Due to its properties, this material allowed to produce reliable, easy-to-install cables with very low loss ratio for high and extra high voltage systems.
