The world where darkness is gone and light always stays The way to connect you to the world and lead you to a better tomorrow Taihan makes that way We are pushing forward with the eco-friendly and high-efficiency cable product development based on robust-based technology and continuous research-oriented policy and contributing to the various renewable energy industries soft-landing. Based on successfully installed submarine cables for local projects, i.e. Yeosu-Janggoon Island, JeollaNam-do Jang-Juk Waterways, Busan Yeongdo Bascule Bridge, Ulsan Newport and Gunsan Port, further, Seychelles Archipelago in Africa, We secured an order for the largest-scaled offshore wind farm development project in Korea, which is the West-South Offshore 2.5gigawatt Wind Farm Project Test Bed R&D work and supplied & installed. Besides, we made splendid achievement of securing Inter-array Main Project. Designed and established as an eco-friendly smart factory style, Dangjin Plant holds the world's tallest VCV tower whose height is 160.5 meters and state-of-the-art exclusive production line for high-quality submarine cables. we can produce and provide maximum diameter 175mm, length 10km submarine cables. We have our own test equipment enabling all kinds of test performances. In 2016, we achieved the certification and KEPCO for 22.9kilovolt submarine cables. We demonstrated J-tube pull-in test for offshore wind towers and product reliability was verified based on specific installation conditions, accordingly. Cable shipment is normally made at Pyeongtaek Seaport of which berth capability is around 50,000 metric ton and quite adjacent to Dangjin Plant. For the best transportation and shipment of submarine cables, our professional engineers have already secured the safest and fastest land transportation route from Dangjin Plant to Pyeongtaek Seaport based on sufficient experiences. We have deep empirical knowledge to have been accomplished cable shipping work without any problems despite the harsh environmental conditions of large tidal range of the West Sea. For the sake of the safest installation of the submarine cables in the various enviroment, Taihan close technical collaboration together with the prominent domestic and foreign submarine cable installation companies. Sincerely based on the precious past experiences in product delivery and construction work of offshore wind farms, Taihan has been erected as much successful track records and is further stepping into the world markets. Taihan will never stop stepping forward as a socially matured and responsible leader in the global cable industry by manufacturing the world's best quality submarine cables.

The world where darkness is gone and light always stays The way to connect you to the world and lead you to a better tomorrow Taihan makes that way Overhead Transmission Conductor! Offering the highest degree of conductivity in the world. The overhead transmission conductor is now evolving from traditional ACSR to HTLS type. HTLS type, High temperature low sag, offers cost reduction, improved capacity and conductivity, and minimization of civil complaints such as noise and light issues. Taihan ACCC is the most optimized HTLS overhead transmission conductor that leads the market trends and satisfies the customer’s needs. Unlike ACSR with steel core, ACCC’s composite core consists of carbon-glass fiber and epoxy resin. Compared to steel core in the same diameter, carbon composite core offers higher tensile strength, lower coefficient of thermal expansion rate, and lighter weight. Even material of conductor and the shape of wire are differentiated. While traditional ACSR uses hard aluminum round type wires, ACCC uses fully annealed trapezoidal type aluminum wires, which doubles the conductivity of traditional ACSR. ACCC has 28% higher sag improvements and 30% stronger tensile strength. Thanks to these features, ACCC is the perfect solution for low sag demanding conditions and long span conditions such as cross-country or sea crossing site. While ACCC can easily withstand heavy electrical load conditions such as near power plant areas, it also can be applied near metropolitan areas for enhancing transmission capacity. ACCC’s safety and efficiency is recognized through over 70,000km ACCC supply to more than 30 nations. Taihan has a record of supplying over 1,100km of ACCC throughout the world including SCE 110kV transmission conductor replacement project in the United States and 110kV project in Vietnam. In Korea, its construction features, maintainability, and economic feasibility have been recognized through various projects and researches starting with Je-ju Demonstration Project in 2011 carried out by KEPCO, pilot projects carried out in Go-chang, Young-kwang regions and cooperative research carried out by KEPCO. Then, with the performance of forest fire trial examination, heat-resisting property and safety of carbon fiber composite core support wire have been verified. Through this verification, Taihan supplied ACCC in the project carried out in 2018 where 12km of 154kV ACSR in between Shin-deogeun and Su-saek substation was replaced with HTLS type transmission conductor. Moreover, through the strategical technology cooperation with CTC, ACCC composite core manufacturer, Taihan succeeded in developing AZR with enhanced mechanical features of ACCC. ACCC AZR offers more ACCC AZR conductor offers nearly the same efficiency, but far greater overall strength. The added strength and increased tensile modulus mitigates conductor sag under heavy wind or ice loads, or very long spans conditions such as Korea, Canada and Russia. Taihan is producing the best quality products with exclusive ACCC production line and finished product test facilities in Taihan VINA in Vietnam and Dangjin plant in Korea, the largest wire manufacturing factory in the world. From maximum diameter 44.75mm and maximum 3,189A of current allowance, Taihan offers customized specifications to the customers. Through blasting facilities, Taihan is able to produce ACCC in non-specular type, which complies with the non-specular regulations in North America. Moreover, Taihan ensures perfect product quality and reliability by conducting self-verifications through the utilization of our own facility. In the future, based on our excellent technical skills, production capability and supply record, Taihan shall contribute not only in safe power grid construction, but also in customers’ value creation by supplying transmission conductor that meet different demands of customers. Taihan will never stop stepping forward as a socially matured and responsible leader in the global cable industry by manufacturing the world's best quality ACCC.
