Taihan Secures a Landmark 230kV Extra-High Voltage Power Grid Project in SingaporeOn December​ 11, Taihan signed a contract with Singapore's SP PowerAssets Limited for a 230kV Extra-high voltage power grid supply project. With a total value of KRW 140 billion, this large-scale project marks a significant achievement for the company. As a full turnkey project, Taihan will oversee the entire process, including the production, installation, connection, and testing of 230kV OF (Oil-Filled) cables and related cable accessories. Beyond this milestone, Taihan secured additional orders totaling KRW 220 billion in the United States and Sweden in November and December. These successive wins across the U.S., Europe, and Asia highlight the company’s global competitiveness and leadership in the cable industry. OF (Oil-Filled) cables are recognized as high-value-added products due to their exceptional electrical performance and reliability. These cables utilize insulation oil to form a robust insulating layer, but their complex production process and stringent maintenance requirements mean that only a select few companies worldwide can manufacture them. Taihan, having developed and commercialized OF extra-high voltage cables for the first time in Korea in the 1970s, has maintained its position as a leader in the extra-high voltage market.​ 

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.
