International Certification for EHV Submarine CableTaihan Cable & Solution has completed the development of a 154kV EHV submarine cable system and obtained KEMA international certification. KEMA is an accredited testing organization based in the Netherlands, highly regarded internationally in the field of electrical safety. The 154kV class submarine cables are primarily used for connecting offshore wind farms to the mainland through export cables, and for interconnections between lands and continents.   Taihan plans to produce the 154kV at its submarine cable plant 1 at Godae Pier in Dangjin City,which will be completed in 2025. Having developed and secured certification for this cable, Taihan is now positioned to bid on various submarine cable projects both domestically and internationally.​ 

Taihan had won a project for a 500kV EHV power project in EgyptTaihan Cable & Solution announced on February 22nd that it had won a project for a 500kV EHV power project ordered by the Electric Power Systems Engineering Company, a joint venture of the Egyptian government. This project involves linking an existing substation and a new HVDC converter station in the Badr region, located in the northeast of Egypt, with underground power cables. Taihan will supply 500kV HVAC cables and oversee the project management. With this order, Taihan has made its first entry into the Egyptian EHV market. 500kV is the highest voltage used in Egypt. Taihan succeeded in pioneering the market, breaking through the competition not only with local companies but also with leading global companies.  

Taihan has secured a contract for a 380kV EHV power network project from Germany's TenneTTaihan Cable & Solution has secured a contract for a 380kV Extra High Voltage (EHV) power network project from Germany's TenneT, valued at 60 billion won.  This project involves the construction of 380kV underground cables in Germany to expand the transmission network necessary for environmentally friendly wind power generation. Taihan will supply all materials including EHV cables and cable accessories, and will handle everything from power network design to cable laying, connection, and testing. Last year, Taihan had successfully won two projects in Germany worth a total of 70 billion won, marking its entry into the German high-voltage market. With this latest large-scale project, Taihan has further reinforced its competitiveness in the German market.  

Taihan Secures $65 Million Power Grid Project in KuwaitTaihan has reaffirmed its competitive edge in the Middle East market by securing a major project in Kuwait. The contract for the EHV Power Grid Turnkey Project, commissioned by the Kuwait MEW(Ministry of Electricity and Water & Renewable Energy), was awarded to the company for $65 million. This significant undertaking involves the construction of an underground power grid connecting existing substations in Kuwait City, the country's capital. The project aims to respond to the city’s increased power demand as smoothly as possible. It will be carried out in a turnkey manner, with Taihan responsible for all phases, including the supply of 300kV grade EHV cables and accessories, power grid design, installation, connection, and testing. Relying on its long-accumulated Middle Eastern network and technical prowess, Taihan is committed to securing more contracts in the future.

Construction for the extra-high-voltage cable factory in Saudi ArabiaTaihan appears ready to step up its local investment plan in Saudi Arabia. On the 15th, the company signed a new contract at Hoban Park Building #2 (Umyeon-dong, Seocho-gu) on creating a joint venture (JV) tasked with building an extra-high voltage cable production plant in Saudi Arabia. Taihan’s joint investor for the project is the Mohammed Al-Ojaimi Group, an EPC specializing in the transmission and distribution of electricity across Saudi Arabia. Taihan is set to invest 51% of the USD 80 million in total investments (approx. KRW 100 billion) for this new project. The factory will be built on a site stretching across 70,000m2 in a high-tech industrial complex located in Riyadh, the nation’s capital. Once the factory is complete, Taihan will begin the local production of extra-high-voltage cables and power equipment required in extra-high-voltage power grids, and this, in turn, will have a positive impact in helping the company secure the technology and competitive pricing it needs to grow its business in the Middle East, Europe, and Africa. 

Taihan wins major order worth KRW 74 billion in SingaporeTaihan has won a new order for a 400kV extra-high-voltage cable power network construction project worth approximately USD 50 million (approx. KRW 60 billion) commissioned by SP PowerAssets, a Singapore power company. The project is to build an underground power grid on Jurong Island, located in the southwestern corner of Singapore. Taihan will employ a full turn-key method to supply all 400kV extra-high voltage cables and cable accessories, and it will take care of designing, pulling, connecting, and testing the power grid. 

Cross-linked polyethylene (XLPE) is polyethylene (PE) whose chemical structure is modified by cross-linking reaction and has a high allowable operating temperature of 90℃ and excellent electrical properties. As the problem of water tree, which is considered as a biggest weakness, has been improved with the development of manufacturing technology, XLPE is now widely used as an insulation material for power cables of various voltages as well as extra-high voltage.

Oil-filled (OF) paper insulation cables have a history of over 100 years, and use insulating paper impregnated with low-viscosity insulating oil as an insulator. By applying a pressure higher than atmospheric pressure, the gap in the insulator is completely removed and as a result, the cables have very good electrical properties.

The extra-high voltage DC cables (HVDC) convert AC power into DC power before transmission. Since they have low transmission loss and can transmit more than twice the current, they are suitable for long-distance large-capacity transmission. Taihan has developed HVDC 500kV MI cables insulated with polypropylene laminated paper (PPLP) and HVDC 500kV XLPE cables insulated with cross-linked polyethylene (XLPE) according to the insulation method required by the consumer.

Participated in Bitgram International Exposition of Electric Power Technology (BIXPO) 2021​Taihan participated in Bitgaram International Electric Power Technology Expo (BIXPO) 2021 held at Kimdaejung Convention Center, Gwangju, from November 10 to 12.  At BIXPO, a representative international comprehensive energy expo hosted and supervised by Korea Electric Power Corporation, Taihan introduced its new and renewable energy-related businesses such as submarine cables and solar PV cables oriented to the theme of Carbon Neutrality, and unveiled related products.  Taihan also presented a development process of a new technology in the solution field, such as a Direction-Changeable Laying Device, imprinting its excellent technology on the visitors.
