Company profile
Connect power and data from the seabed to the data centre
Prysmian makes the physical links behind electrification and digital networks. Its systems range from submarine and underground high-voltage cables to building wire, optical fibre and data-centre connectivity. The group also engineers entire links, installs them with purpose-built vessels and monitors assets after commissioning, joining materials science, factories, marine operations and network analytics in one delivery chain.
Power grids and monitoring
Build the cable, protect it and read its condition
Transmission and distribution systems include P-Laser thermoplastic cables, E-PATH-labelled products and accessories for high-, medium- and low-voltage networks. PRY-CAM adds continuous or temporary monitoring from 3 kV to 600 kV, turning electrical and environmental measurements into evidence for maintenance teams.

Digital infrastructure
Fit 864 optical fibres inside a cable less than one centimetre wide
Digital Solutions spans fibre, copper, connectivity, telecom access and data-centre infrastructure. Sirocco Extreme uses 180-micrometre BendBrightXS fibre and PicoTube technology: its 864-fibre version measures 9.8 millimetres across, helping operators add capacity inside congested ducts rather than excavating new routes.

Vessels and production
Lay deep-sea cables from a floating factory supplied by a vertical one
Prysmian Monna Lisa is 171 metres long, carries 17,000 tonnes of cable in two carousels and is designed for depths beyond 3,000 metres. At Pikkala in Finland, a 185-metre vertical production tower can make about one kilometre of 525 kV submarine cable per day.

Landmark links
Join islands and national grids across extreme routes
The Tyrrhenian Link uses lightweight synthetic armour for a record 2,150-metre installation trial. Viking Link combines roughly 1,400 kilometres of land and submarine cable between Britain and Denmark. NeuConnect adds a 725-kilometre, 1,400 MW UK-Germany route, while SuedOstLink takes 525 kV underground technology across Germany.

Ten-year data-centre agreement
Prysmian signed an optical-cable supply agreement with Molex worth up to €5.5bn over as many as ten years, including a €550m upfront payment.
Fibre capacity expansion
The group allocated €1.25bn through 2031 to expand optical-fibre and cable capacity in the United States and Europe, with more than 1,000 jobs expected worldwide.
Hollow-core fibre at deployment scale
Tests installed Prysmian's high-density hollow-core cable at up to 350 ft/min; its North Carolina plant produced a 24-fibre, 10mm cable meeting customer attenuation requirements.
Margin expansion
Q1 adjusted EBITDA increased 14.0% to €601m, while the margin at standard metal prices rose to 14.2% from 13.1%.
