South Korea’s LS Cable & System announced that it has signed a contract with TenneT Offshore to supply high-voltage direct current (HVDC) cables worth about

1.5 trillion won ($1.2 bil1ion).

A press release said that LS Cable & System, in a consortium with Belgian construction companies Jan De Nul and Denys, has won a total of four projects connecting the North Sea to Germany. Under two of the contracts, LS Cable & System will supply submarine and underground cables starting in 2026. The remaining two contracts are expected to be awarded sequentially through 2026.

The projects stem from a 2022 agreement by Denmark, the Netherlands, Belgium and Germany to jointly install 65 gigawatts (GW) of offshore wind power by 2030. TenneT will participate in the project, which will supply up to 35 million homes with green wind energy.

“Although power grid construction projects are becoming more active around the world, HVDC cables require large-scale investment and high technical skills, so a small number of global wire companies such as LS Cable & System occupy most of the market,” said an official from LS Cable & System.

The search for a room-temperature superconductive material has long been pursued, but so far it has remained a scientific theory. There is widespread interest in recent claims from South Korean researchers who believe that LK-99 could be for real. While further assessment of K-99 may well show that it is not “for real,” that possibility is hard to ignore.

Word that a new superconductor—LK-99—can work at room temperatures or higher, and at ambient pressure, recently fueled an online frenzy that led to much discussion as to whether it could for real. By press time, the story that broke in July and was abuzz in early August may not just be yesterday’s news, but yesterday’s news refuted, as there are many questions about the concept from Sukbae Lee and Ji-Hoon Kim, and colleagues, of South Korea’s Quantum Energy Research Centre.

Per Wikipedia, LK-99 is a potential room-temperature superconductor with a gray-black appearance that is said to have a hexagonal structure that is slightly modified from lead‒apatite by adding small amounts of copper. In 1999, a Korea University team led by Lee and Kim claimed that the material acts as a superconductor at temperatures below 400 K (127°C/260°F) and at ambient pressure. Not much happened until recently, when a July 22 technical paper by Lee and Kim (their names led to the LK-99 tag) jolted the technical field as they implied that room-temperature capability may be possible.

On Aug. 4, 2023, a report sent to SBS News said that high-quality LK-99 samples may exhibit diamagnetism 5,450 times greater than graphite, while low-quality samples may demonstrate an effect up to 23 times stronger. The only way that could be, the report said, is if the substance is a superconductor.

A recent story in BusinessKorea said that the Korean Superconductivity Society recently established a committee of experts to verify LK-99, a room-temperature superconductor developed by Korean researchers affiliated with the Quantum Energy Research Center (QERC) among others. The society said it plans to provide samples produced by the QERC for testing.

While LK-99 would be a stunning advance if it was found to be scientifically verified, several wire and cable manufacturers have been working on them, albeit with technology that does not work at room temperatures.

In 2021, South Korea’s LS Cable & System developed a next-generation 23 kV triaxial superconducting cable and obtained an IEC on the product. Currently, only three companies in the world can make superconducting cables, and LS Cable & System notes that it is the only one that established an international standard for a triaxial superconducting cable.
WJI asked LS Cable & System whether it was involved in any way with the research into LK-99, and got the following reply. “The superconducting cable commercialized by LS Cable & System is a product with a different technology from LK-99, which has recently become an issue.”

That response did not state that South Korea’s LS Cable & System was not interested in the potential of LK-99, only that at this point it is not part of the current activity.

LK-99 technology is worth pursuing as multiple reports note that its hoped-for potential would be an amazing advance. It has been likened to the search for the Holy Grail, yet it also evokes decades-old memories of claims of “cold fusion” for nuclear energy that never materialized. And yes, there are skeptics for LK-99.

To date, there has been no scientific validation of LK-99, although there was one report of observed superconductivity at 110 K by a team from Southeast University, China. However, the absence of the Meissner effect (a defining characteristic of superconductors) was questioned as well as the testing method.

There has been considerable response, most doubting the accuracy of the claims. An article published by Time said that on July 31, researchers from the National Physical Laboratory of India uploaded a paper that found that LK-99 is not superconductive. Veerpal Singh Awana, chief scientist at the National Physical Laboratory, posted details online outlining his group’s unsuccessful efforts to replicate the findings. Also, researchers from Beihang University in Beijing uploaded a paper on July 31 that found that LK-99 is not superconductive.
Other warning flags were that there was no heat anomaly test and no definition of “zero resistance.”

An editorial in The Hindu was blunt. “For another claim this year, of a material that reportedly superconducts near room temperature and under much less pressure than others of its kind, its originators shared instructions to synthesize it but refused to share samples, claiming they constituted intellectual property. While this may be, their refusal vitiated the proper process of science in the face of such an extraordinary claim.”

Another on-line article, in the Korean Joongang Daily, said that a researcher from the Korea Institute of Energy Technology (Kentech) “confirmed that the crystal structure of LK-99 is in line with what has been suggested in manuscripts put forward by the Korean scientists, according to local media reports.” At the same time, it noted that The Korean Society of Superconductivity and Cryogenics looking into the claims believes that “based on the studies and footage, the material appearing in the research and the footage cannot be considered as a room-temperature, ambient-pressure superconductor.”

But for now, LK-99 is front and center, and multiple Korean researchers are assessing the technology. If it is deemed feasible, more than one wire and cable manufacturer would be very, very interested.

South Korea’s LS Cable & System (LS C&S) reported that it has signed an agreement to supply high-voltage submarine cable to Ørsted for renewable energy projects in Taiwan, where it notes that it has done extremely well.

A press release said that LS C&S will supply the cable for Denmark’s Ørsted—which it has partnered successfully with—for use in its Greater Changhua 2b and 4 offshore wind projects in Taiwan. Located 35 to 60 km from the Changhua coast in western Taiwan, it will be among the largest offshore wind farms in the Asia-Pacific region when it is completed at the end of 2025, able to generate 920 MW of renewable energy.

With the latest order, LS C&S has supplier rights for all eight projects of the Taiwan’s Phase 1 Offshore Windfarm Construction Projects. The accumulated amount of orders since 2019 are worth approximately 1 trillion won (about $776 million).

Taiwan is planning to complete the construction of offshore wind farms with total output of 5.5 GW through the first phase of the project by 2025 and will build additional offshore wind farms for an additional output of 15 GW by 2035. “We expect additional orders to be placed from Taiwan and estimate that the submarine cable market will be worth around 3 trillion won (about $2.328 billion),” an LS C&S spokesperson said.

The release said that LS C&S expects to see further positive results from its relationship with South Korea’s KT Submarine. Last December, LS C&S paid about $19.3 million to acquire 16% of the share of KT Submarine, an underwater construction firm that provides installation and repair services for submarine cable.

LS C&S notes it also has a call option that it can exercise that would enable it to be the largest shareholder in the company. Further, there are only about five companies in the world capable of both submarine cable manufacturing and construction, and LS C&S is the only company in Korea to be capable of such services.

LS Cable & System (LS C&S) has completed what it described as Asia’s largest high-voltage direct current (HVDC) underwater cable production plant in Donghae, Gangwon Province, South Korea.

A press release said that the Donghae plant, named Submarine Building 4, is a 172-m-tall vertical continuous vulcanization (VCV) tower with a total floor area spanning 34,816 sq m. Approximately $141 million was spent since construction that started in July 2021.

Since building South Korea’s first submarine cable plant in 2008, LS C&S has made significant investments in its submarine business. The company also recently purchased stakes in KT Submarine, a submarine cable maker, becoming the largest shareholder (43.8%).

“The completion of this HVDC plant will serve as an accelerator for growth in the era of energy transition and the rise of the power industry,” said LS C&S CEO Koo Bon-gyu. “We will contribute to the advancement of the electric power industry through the construction of efficient energy networks and the enhancement of national competitiveness.”

Last December, LS C&S won a contract to supply HVDC cables to the Vanguard Wind Power Complex in the U.K., Korea’s largest cable deal signed to date in Europe.
More than 100 key persons—including LS Group Chairman Koo Ja-eun, LS Corp, CEO Myung Roe-hyun and LS C&S CEO Koo Bon-kyu —attended the completion ceremony.

South Korea’s LS Cable & System (LS C&S) has won an order valued at $167 million to supply high-voltage, direct current (HVDC) cables for the Norfolk Boreas Offshore Wind Farm in the U.K.

A press release said the LS C&S order is from Sweden’s Vattenfall AB, which is one of Europe’s largest producers and retailers of electricity and heat. The order calls for 320 kV cables that will lie under the sea. The underground cables will use cross-linked polyethylene (XLPE) as an insulating material, which it described as a first.

Per multiple media reports, the Norfolk Boreas offshore cable corridor, using about 96 km, will include export cables to deliver the electricity supplied to the offshore substations to landfall that will be in the Happisburgh village in Norfolk county. The onshore part of the offshore wind farm development will include the installation of underground cables between an onshore substation related to the project and an existing substation of the national grid. The onshore cable corridor is expected to be 63 km.

Located 47 km off the Norfolk coast, Norfolk Boreas is the first of two stages of Vattenfall’s Norfolk Offshore Wind Zone. Per DEME Offshore, which is part of the project consortium with LS C&S, they have also been named a preferred supplier for the second part: the Norfolk Vanguard. Each wind farm will have a capacity of 1.8 GW.

“Only a handful of firms have succeeded in developing XLPE cables defined by easy installation, connection, maintenance and repair,” an LS Cable & System official said. “The cables are increasingly emerging as a mainstream product in the renewable industries of Europe and North America.”

LS Cable & System announced on Oct. 20 that it has won a cable contract valued at approximately $166 million to supply the Boreas wind farm in the North Sea of the U.K., the largest ever order from Europe received by a South Korean cable company.

Per the announcement, the Boreas offshore wind farm is being developed by Sweden’s state-owned power company Vattenfall, near Norfolk in the United Kingdom. When completed in 2026, it will produce about 1.3 GW of electric power, equivalent to one nuclear power plant.

LS Cable & System will supply 320 kV ultra-high voltage direct current (HVDC) submarine and underground cables for the wind farm. It will mark the company’s first supply of HVDC cables that use cross-linked polyethylene (XLPE) as an insulating material.

XLPE cables are becoming the mainstream in renewable energy projects in Europe and North America due to their convenient installation and connection and easy maintenance. However, so far, only a few companies have succeeded in developing them. The latest order is expected to help LS Cable & System accelerate its penetration of the XLPE cable market. The company plans to expedite its market expansion in Europe as well as North America and Asia where demand for XLPE cables is growing rapidly.

LS Cable & System USA, part of South Korea’s LS Cable & System, plans a $26.9 million investment to expand its plant in Tarboro, North Carolina.

The announcement said that the company’s campus in Edgecombe County will be expanded over a three-year period. The investment will increase the current manufacturing capacity and add an additional 86 employees to the current staff of 188, said Bobby Piner, the plant’s manager of manufacturing. “This expansion will allow (us) to meet the current and growing needs of our customer base while providing job growth opportunities for our team members in Tarboro.”

LS Cable & System USA designs, manufactures and distributes an array of cable products for the rapidly growing energy sector within commercial, industrial, renewable and utility markets. The Tarboro plant, which makes low- and medium- voltage cables, opened in 2012.

4/3/2022 - Earlier this year, LS Group’s cable manufacturing unit, LS Cable & System (LSCS), officially opened its new power cable plant in Indonesia, a joint venture.

A press release said that the new plant, called LSAGI, is a joint venture between LSCS and Artha Graha Network, Indonesia’s 10th-largest conglomerate. The Korean firm owns a 75% stake in the entity.

The plant, located on a 64,000-square-meter site in the Artha Industrial Complex near Jakarta, will mainly produce overhead wires for power transmission and distribution and low-voltage cables for buildings and plants.

LSCS said it aims to expand its presence in the Southeast Asian country by taking advantage of its local partnership business experience and sales networks ranging from banks to hotels. “In the cable industry, each country is strengthening policies to protect its own companies,” an LS official said. “We will pursue different strategies for different markets to better meet the local demands.”

The firm also expected a quick recovery of the pandemic-hit cable market, citing Indonesia’s planned relocation of its capital from Jakarta to a jungled area of Kalimantan on Borneo island, which involves a $32 billion mega development project. LSCS now operates a total of 12 production facilities around the world, including in the U.S., Poland, Vietnam and China.
