Submarine cable energy storage equipment manufacturing

How many submarine cables have we supplied in the past 100 years?

We have supplied over 6,000*km of submarine cables in the past 100 years. Submarine cable is a vital component of offshore renewable energy (RE) projects such as wind farms. While submarine cables are sometimes installed in harsh environments that include currents, water pressure, high waves, or unforeseeable obstacles on sea beds.

What is submarine cable & how does it work?

Submarine cable is a vital component of offshore renewable energy (RE) projects such as wind farms. While submarine cables are sometimes installed in harsh environments that include currents, water pressure, high waves, or unforeseeable obstacles on sea beds. The installation of submarine cables requires much sophisticated technologies.

Where are Prysmian's submarine manufacturing centres of Excellence located?

We create those vital connections that ensure energy and information is carried effectively, efficiently and sustainably. Our Submarine Manufacturing centres of excellence are located in three different countries: Prysmian Group's Submarine Cable Manufacturing centers of excellence are located in Italy, Finland and Norway.

Why are cable systems important in HV & submarine power transmission grids?

In HV & Submarine power transmission grids cable systems represent a high-value asset to be preserved and each non-transmitted MW is a financial loss factor. Prysmian is a leader in the supply of high voltage cables that extend over land and by sea connecting countries and continents. Find out more!

What are Prysmian submarine interconnectors?

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.

What is a high voltage submarine cable?

High Voltage AC submarine cables are 3-core or single core armoured, with copper or aluminium conductors, XLPE insulation and lead sheath over each insulated core as a radial metallic water barrier. Available voltage ratings range from 150 kV to 400 kV. Standard HV submarine cable designs typically include one or more optical units.
