High-voltage systems

High-voltage systems 2

For the transmission of electricity in high voltage networks (HV: UN 36-150 kV), the highest 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 economic importance, the particularly restrictive requirements for economic 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 enabled the production of reliable, easy-to-install cables with very low loss ratio for high and extra high voltage systems.

This enables cable systems to:

  • avoid interfering with the present infrastructure 
  • achieve a high degree of reliability and safety
  • maintenance-free operation
  • minimum interference in the environment (the low value of the magnetic field near the cable track)
  • avoid negative effects on the landscape

The cable systems are used when connecting objects of special economic features, where the priority is to ensure the continuity of power transmission as well as for areas of high landscape value.

TF Kable belongs to a narrow group of reputable suppliers of such systems, offering cables with cross-sections up to 3000 mm2 and voltage of up to 500 kV. The first 110 kV cable system was produced in 1992, giving us many-years’ experience in the design and production of HV and EHV cables. Few in the world and no others in Poland can say the same.

The HV department supports customers in the field of HV cable systems through:

  • design and optimisation of cable construction, including calculations of loading and all relevant electrical parameters
  • preparation of complex offers for the HV and EHV systems, covering delivery of cable and accessories, installation and post-installation testing
  • advice on the design of the cable systems: selection of other cable system elements and optimisation of cable working conditions etc.
