Overview
Prysmian Group is an Italian multinational focused on cable systems and related infrastructure for energy transmission, power distribution, telecommunications, construction, transportation and industrial applications. Headquartered in Milan, the group operates internationally through manufacturing facilities, engineering capabilities and installation services across Europe, North America, Latin America, Asia-Pacific and the Middle East, Africa and Turkey. Its portfolio spans high-, medium- and low-voltage power cables; underground and submarine transmission systems; cables for renewable-energy projects; optical fibre and fibre-optic cables; copper telecommunications cables; and specialised products for sectors such as automotive, aerospace, rail, mining, oil and gas, data centres and industrial automation. The business traces its roots to Pirelli Cavi e Sistemi, whose early cable activities began in 1879. In the late nineteenth and early twentieth centuries, the company developed submarine telegraph cables, supported Italy's national telegraph and telephone networks, and participated in the electrification of Milan. Its historical activities also included long-distance and international communications infrastructure. The modern Prysmian company was formed in 2005 after Goldman Sachs acquired Pirelli's cables and systems business. Prysmian subsequently became a publicly traded company, listing in Milan in 2007. A major expansion occurred in 2011, when Prysmian acquired Dutch cable producer Draka. The transaction broadened the group's geographical reach and strengthened its position in optical fibre and telecommunications cables. In 2017, Prysmian agreed to acquire General Cable, a large United States-based competitor. The transaction was completed in 2018 and created a substantially larger global cable group, with operations in more than 50 countries and a broad manufacturing and service footprint. General Cable added significant North American, Latin American and other international operations, as well as further exposure to power, construction and communications markets. Prysmian combines product manufacturing with project design, cable-laying, system integration, testing and maintenance. This is particularly important for high-voltage underground and submarine links, offshore wind-farm connections and other infrastructure projects where cable supply is only one part of the customer requirement. The group is widely associated with cable systems for renewable energy, including offshore wind, and with large-scale interconnection and grid-modernisation projects. Research and development is central to the company's competitive positioning. Prysmian has developed high-performance optical-fibre and cable technologies such as BendBrightXS, designed to improve fibre performance where cables must withstand tight bends, and FlexRibbon, a high-density optical cable architecture. Its P-Laser technology is intended to provide high-voltage cable performance while using recyclable materials and reducing environmental impact compared with conventional cable technologies. The company has also invested in sustainability initiatives covering emissions, materials, energy use and supply-chain performance. The group operates a fleet and project capability for submarine cable installation, including the Leonardo da Vinci vessel, introduced as a major addition to its cable-laying capacity. Prysmian's current business scope therefore extends beyond the traditional image of a cable manufacturer: it is also an engineering and infrastructure-services provider whose products support electricity decarbonisation, grid expansion, digital connectivity and industrial communications.
History
Prysmian's corporate history reaches back to 1879, when the cable business that later became associated with Pirelli Cavi e Sistemi was established. The company entered submarine communications early: in 1881 it obtained a contract for submarine telegraph cables used in military engineering, and in 1886 it opened a dedicated submarine-cable plant in La Spezia. These activities helped establish technical capabilities in long-distance communications, cable insulation and marine installation. During the following decades, the business participated in the construction of Italy's communications infrastructure. It supplied cables for the national telegraph network and contributed to the development of Milan's domestic electricity grid. It also undertook communications-related work in Italian East Africa. In 1925, it produced thousands of kilometres of submarine telegraph cable for Italcable's communications links between Italy and South America. Cooperation with the Italian government continued through work on the interurban telephone network. The business later developed into a broad cable and systems operation within the Pirelli group. Its activities expanded from telecommunications and electricity infrastructure into industrial cables and specialised applications. In 2005, Goldman Sachs acquired Pirelli's cables and systems division and established Prysmian S.r.l. as an independent business. After organisational restructuring, Prysmian pursued a more focused cable strategy and prepared for a public-market listing. Prysmian became listed on the Milan stock exchange on 3 May 2007 and joined the S&P MIB index later that year. Goldman Sachs reduced and ultimately exited its investment by March 2010. The company then entered a period of international consolidation. In 2011, Prysmian completed a takeover of Dutch cable manufacturer Draka for approximately €840 million. Draka was a significant producer of cable and optical-fibre products, and the acquisition strengthened Prysmian's position in communications technology and expanded its international operations. The next major step was the purchase of General Cable, announced in December 2017 and completed in 2018. General Cable, headquartered in the United States, was a substantial competitor with operations across multiple regions. The transaction was valued at approximately US$3 billion, including equity consideration and the assumption or refinancing of debt. It combined Prysmian's existing global position with General Cable's manufacturing, distribution and customer relationships, creating a group with operations in more than 50 countries and tens of thousands of employees. Following the acquisition, Prysmian operated a large network of plants and project locations across Europe, North America, Latin America, Asia-Pacific and the Middle East, Africa and Turkey. Its business was organised around energy and telecommunications, with additional specialised cable activities. The company increasingly combined manufacturing with engineering, installation and maintenance, allowing it to bid for complete cable-system projects rather than only supplying cable products. Innovation has remained a recurring theme. Prysmian has invested in optical-fibre technologies for high-density and difficult installation environments, including BendBrightXS and FlexRibbon. In power cables, P-Laser technology has been promoted as a recyclable and lower-impact alternative for selected high-voltage applications. The group has also built capabilities for offshore wind and submarine interconnection projects, areas supported by the expansion of its cable-laying fleet. The Leonardo da Vinci vessel, introduced in the early 2020s, strengthened its ability to install large submarine cables. The company's present identity is consequently shaped by several overlapping legacies: nineteenth-century submarine telegraph engineering, twentieth-century national electrification and telecommunications work, the separation of the cable business from Pirelli, and later consolidation through the Draka and General Cable acquisitions. Prysmian now presents itself as an infrastructure technology group serving the energy transition and the growth of digital networks.
