Prysmian S.p.A. is a multinational company with headquarters in Milan, Italy, specialising in the production of electrical cable for use in the energy and telecom sectors and for optical fibres.

On 4 December 2017, it took over 100% of the General Cable group in the US, to then complete the merger by incorporation the following year, after the antitrust approval by the respective countries.

[12][13] In February 2011, Prysmian successfully made a takeover bid of EUR 840 million for Dutch company Draka, with headquarters in Eindhoven, which at the time was fourth in the world in the cable and optical fibre sector.

[16] The acquisition was unanimously approved by the two Boards of Directors and would create a company present in 50 countries with 31,000 employees, which could generate revenue of 11 billion dollars a year, based on estimates from the 2017 financial statements.

[19] Its completion would create a market concentration in a strategic sector for public safety and economic development, which was already established by no more than ten competitors across Italy, the US and China.

The company also developed the P-Laser technology[23] for cabling systems, which combines greater transmission capacity and eco-sustainability, using 100% recyclable materials and cutting carbon emissions by 40%.

By 2022, Prysmian has planned to invest around EUR 450 million[24] to net-zero the Group's CO2 emissions and improve the sustainability of its supply chain.

An ambitious commitment, aligned with the objectives of the Paris Agreement, which would be executed with support from the non-profit organisation Carbon Trust.

For 2021, Prysmian confirmed the launch of the new Leonardo da Vinci cable-laying vessel,[25] which will be the longest in the world at 171 metres.
