The Prysmian Group announced that it has reached a key technology milestone in power transmission: the successful development and testing of the first 525 kV extruded submarine full cable system for High Voltage Direct Current (HVDC) applications.
The breakthrough will enable a massive increase of the maximum transmission capacity of bi-pole systems up to more than 2.5 GW, which is more than double the value achieved with 320 kV DC systems currently in service. The one-year prequalification testing was carried out per international standards including CIGRE TB-496 and witnessed by a third-party certification body.
“This new milestone confirms our commitment and prominent role in the development of power grids infrastructure, key for the energy transition,” said Prysmian Group CEO Valerio Battista.
HVDC cable links are key components of sustainable energy systems, to transmit large bulks of electricity over long distances, often across or between countries. This achievement will put Prysmian Group in a unique position to support forthcoming tenders for submarine interconnectors.
“On the heels of the successful industrialization of 525 kV HVDC underground cables for the 3 German HVDC links projects, we are ready to extend this innovative technology for submarine cable systems to enable our customers in the continuous effort towards the energy transition by further reducing the costs of offshore wind and minimizing the environmental impact,” said Hakan Ozmen, EVP Projects Business Unit.
The company leveraged its in-depth knowledge of materials and the capability to improve manufacturing processes to optimize a reliable industrial process with strict technological parameters and providing an entire system of cable and accessories. That includes flexible factory joints, rigid repair joints and sea-land joints with the best dielectric properties.

Russia’s EVRAZ PLC is seeking to divest the holdings of EVRAZ North America (ENA), which include Rocky Mountain Steel Mill, a plant in Pueblo, Colorado that produces wire rod.
The scope of the story is far larger as a key investor in the parent company is Roman Abramovich, a Russian billionaire who was on the list of oligarchs linked to Russian President Vladimir Putin. EVRAZ Plc, which purchased Pueblo’s steel mills in 2007, was hit with sanctions by the U.K. in May in response to Russia’s invasion of Ukraine.
ENA, based in Chicago, Illinois, employs more than 1,400 people in the U.S. and 1,800 in Canada, with production sites that include Pueblo, one in Portland, Oregon, and four in Canada, per the company’s website.
A report in The Pueblo Chieftain said that a letter sent by EVRAZ to ENA employees said that the “current geopolitical landscape has created a heightened level of uncertainty” over the last five months that has led to “unique challenges” in its day-to-day business operations. “However, we are in a position to change course,” the letter said. “In response to today’s reality, and to best position our organization for long-term success, EVRAZ plc, the parent of ENA, has made the difficult decision to begin a sales process of the North American business.”

Barnes Group announced that it plans to close the production operations at its Engineered Components facility in Bristol, Connecticut, which has a manufacturing focus of producing transmission springs and washers.
Per multiple reports, the demand for such products has declined as there is more production of electric vehicles that do not need those parts. The company also cited supply chain issues and inflation as factors.
The plant, which has some 95 employees, is expected to be completely closed by mid-2023. Work performed at the facility will either be transferred to other Engineered Components manufacturing locations or permanently discontinued.

Outokumpu has agreed to sell the majority of its stainless-steel long products business to the Marcegaglia Group, an Italian entity that owns some 30 steel plants.
A press release said that Outokumpu has signed an agreement to divest the majority of its long products business operations to Marcegaglia Steel Group, a leading industrial group in the steel processing sector. Outokumpu will now focus on its core business of flat stainless-steel products.
The long products operations to be sold represent about 8% of the Outokumpu Group’s sales in 2021. They include: melting, rod and bar operations in Sheffield, U.K.; bar operations in Richburg, U.S.; and a wire rod mill in Fagersta, Sweden. The transaction does not include Outokumpu Long Products AB operations in Degerfors and Storfors, Sweden. Approximately 650 employees in Sheffield, Richburg and Fagersta will transfer to the buyer as a part of the transaction.
“This divestment marks the accomplishment of the turnaround program for the Long Products business in the past two years,” said Outokumpu President and CEO Heikki Malinen. “The sale is a natural step for Outokumpu in line with our strategy to focus on our core business, stainless-steel flat products.”
Outokumpu expects to complete the divestment by the end of this year. Outokumpu Long Products AB’s units in Degerfors and Storfors in Sweden continue their operations for now as part of the Outokumpu Group, and different options are to be evaluated for the future of the units.

Ravicab Cables Private Limited announced that it has acquired Leoni Cable Solutions (India) Private Limited (LCSI), a subsidiary of Leoni AG located in Bengaluru.
A press release said that the acquisition of India’s LCSI “provides an expansion in market reach, extension in product range and finds a perfect synergy with the growth aspirations of Ravicab.” For the acquired business, this means a clear perspective for future development in terms of investment and growth. LCSI, which opened in 2013 with a production area of around 15,000 sq m, had revenues of approximately €25.5 million in 2021 and a workforce of 190 people. The plant manufactures wire and cable for domestic, industrial, signaling applications, and specialty markets.
Ravicab reported that with the LCSI acquisition, it has leverage in the specialty products business of renewable energy and railways with E-Beam cable. Ravicab, has also inherited LCSI’s processes and systems for manufacturing specialized cables, which include iconic brands like Kerpen and Icon.
The sale was part of Leoni’s Wire & Cable Solutions Division (WCS), which it has been divesting. “This sale is another step in the process of gradually selling the WCS division and concentrating our business on the Wiring Systems division (WSD).”
Per Leoni, the currently largest remaining unit in the WCS division is its Business Group Wire Products & Solutions (BG PS), a relatively small unit. “For this unit, too, we are constantly reviewing the optimal setup and the best possible future ownership structure.”
The two central units of the WCS division were the Business Groups Industrial Solutions and Automotive Cable Solutions. In other news, Leoni reports that its two Ukrainian plants—one in the Lviv region and the other in the Ivano-Frankivsk region—have continued to produce wiring harnesses, despite the challenges posted by Russia’s invasion of the country on Feb. 24.
