South Korea’s Taihan has completed construction of a dedicated high-voltage direct current (HVDC) cable test centre as it seeks to strengthen its technological capabilities and expand in global markets, the company said.
The new facility allows simultaneous testing of two 640kV-class HVDC cable circuits and enables fully in-house development, validation and certification. Located at Taihan’s Dangjin Cable Plant, the centre spans about 7,000 square metres and is integrated with existing production infrastructure, supporting testing for both onshore and subsea cables.
Taihan said the centre is expected to shorten development and certification timelines while improving responsiveness to customer requirements. The site brings together a consolidated suite of testing equipment, providing a single environment to verify safety and reliability, including long-term performance qualification testing and temporary overvoltage assessments.
“The HVDC test center is a cornerstone infrastructure that demonstrates Taihan’s technological strength,” Vice Chairman Song Jong-min said at the opening ceremony.
“By internalizing the entire process—from product development and validation to certification—we are now able to proactively respond to domestic and international HVDC projects, including the ‘West Coast Energy Highway’ initiative,” Song added.
Taihan said it will continue to expand its presence in the global HVDC market, supported by its growing technical capabilities.
The company has identified HVDC cables as a key growth area and has increased investment in related technology and infrastructure since developing South Korea’s first 500kV line-commutated converter HVDC cable system in 2022, followed by a 525kV voltage-source converter HVDC cable system.
