The vital link in global transmission

Global energy transition and net zero goals may fail if power grids are not sufficiently integrated, widespread, efficient and smart. To this extent, submarine interconnectors have a critical role to play in the exchange and integration of energy supply between countries all over the world .. There can be no energy transition without cable interconnectors, which transmit power under the sea or via underground cable systems, to create more integrated, efficient and sustainable power grids.

One-stop shop solution provider

We provide the interconnector cable system solutions, using our extensive engineering, manufacturing, and turnkey installation capabilities, with a complete project management approach, to provide the cost-effective, high-power cable connections our customers need. Working in close partnership with them, Prysmian sits at the forefront of the interconnectors sector. In doing so, we’re pushing the boundaries, achieving new levels of performance and economic efficiency in our HVDC cable systems. Our clients then gain the advantage of these benefits, as they carry out the development, extension and upgrading of their power grids.

With our range of extensive manufacturing resources, installation and engineering assets, including our fleet of world class cable laying vessels, we are a single source provider offering full EPCI turnkey cable system solutions to meet our customer requirements. Our full value chain sets us apart, giving our customers a hassle-free single point of contact for all their project needs.

We master the full range of HVDC cable solutions

We can provide all existing cable insulation technologies, both commercial and proprietary ones, thanks to our R&D experience and in-house materials compounding capabilities - a unique characteristic for a cable EPCIM contractor. That includes lapped insulations - Mass impregnated (MI) and Mass Impregnated-PolyPropylene Laminated (MI-PPL) - and extruded insulations - XLPE and Prysmian proprietary PLaser insulation system, a fully recyclable material with a reduced carbon footprint and outstanding electrical performances. For us, innovation is a never-ending process: we aim at further increasing power transmission by enhancing voltage levels and operating temperatures as never done before.

New material development isn't limited to insulations, but we work also on solutions with superior mechanical characteristics to be used in cable armouring. This will enable cable connections at the record water depth of 3'000 metres, further improving our world record installations at 1'650m and 2'200m water depths.

Why Interconnectors?

Interconnectors can be considered the backbone of power grids and are the key elements to make the entire power system more efficient, integrated and smart, enabling energy exchange between different countries, characterized by different consumption patterns. Submarine interconnectors provide economic benefits which are achieved through the delivery of lower cost, as well as an increased efficiency in the use of generated power through the balance of supply and demand across greater geographical areas.
