Interconnectors Solutions


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 engineeringmanufacturing, 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, the Group 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.

The widest product portfolio

We offer an extensive and industry-leading HVDC portfolio to address these needs, with the widest product range available.

That includes the paper-insulated solutions of MI and MI-PPL, and extruded cables with both P-Laser and XLPE insulation systems. For us, innovation is a never-ending process, illustrated by our current activities focused to extend available voltage levels. In that field, we’re currently developing an 800 kV P-Laser capability, to add to our current 600 kV solutions. We’re also hard at work researching systems and methodologies to enable cable connections to be made at increased water depths, reaching 3,000 metres.

Our key success factors

One of our greatest assets is our capability to provide a comprehensive package for our customers. With our end-to-end service, utilising 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.

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. Interconnectors increase the security of supply of electrical energy to specific countries, and can help promote the integration and development of renewable energy.
