OVERVIEW

Linking worldwide progress to global power

To countries, to cities, to homes. On land and under the seas. Prysmian is bringing power and communications to the world. As the demand for both continues to soar and industries move steadily towards more renewable and sustainable energy sources, Transmission System Operators (TSOs) are increasingly engaged in developing, extending and upgrading their power grids. This involves the transmission of power via interconnectors that stretch across land and under seas, between countries and continents.

Our commitment to the energy transition

The transition from fossil fuels to renewable energy requires an efficient, smart, and robust energy grid to meet the special challenges of managing these discontinuous power sources. Interconnectors are an increasingly important part of power grids, allowing for connections between countries and even continents to ease the flow of affordable and clean energy across long distances. They are a key part of the energy transition: supporting the implementation of a larger, more integrated, efficient and sustainable power transmission system. Prysmian’s submarine interconnectors are made of new, lighter materials and can go deeper under the sea than ever before. Our high-voltage underground interconnectors can bring power more efficiently over long distances from where the energy is produced (like offshore wind farms) to where energy is consumed. To accelerate the race to net-zero CO₂ emissions, Prysmian plans to invest over 450 million euro by 2022 to further improve the sustainability of its organization and supply chain, and to accelerate the development of advanced cable technologies as well as assets and services.

An Innovation leader

Prysmian is an innovation leader in both high-voltage submarine and underground cable system. Our Research and Development labs have created a submarine cable with new synthetic armour which can be up to 50% lighter than others, enabling Prysmian to perform ultra-deep installations or up to 3,000 meters in marine ecosystems previously considered impossible. For underground power transmission, we have designed new ±525 kV HVDC cable systems, qualified with P-Laser and XLPE insulation, with a higher voltage capacity and with large conductor cross-sections to provide optimal technical solutions for more efficient, reliable and eco-friendly power transmission over long distances.

Leonardo da Vinci – a genius in motion

Prysmian has built a fourth vessel, Leonardo da Vinci, that reinforces the fleet. This new strategic asset will consolidate the Group’s leadership in the submarine cable operations, strengthening our primary role in the interconnection and offshore wind farm markets.

Undisputed world leader in the provision of HV underground & Submarine Transmission cables

We’re the strategic partners for our TSO customers, supporting the development and production of transmission grids, and helping to facilitate the bulk movement of electrical energy from the site of generation to electrical substations. Making innovation a cornerstone of our work, and R&D a constant investment, we offer both HVAC and HVDC cable systems for power transmission for both land and submarine connections.

But we deliver so much more… following the integration of General Cable into the Prysmian Group, we can now call on the strength of NSW and its longstanding expertise in fibre-optic submarine cables, accessories and solutions.
