Milestones

In 2024, Hyosung Heavy Industries became the first in Korea
to localize 200MW voltage-type HVDC (High Voltage Direct Current)
technology using proprietary expertise. The system was installed
at the Yangju substation in Gyeonggi Province, where it now plays
a vital role in stabilizing the regional power grid.

Hyosung Heavy Industries became the first in the world to commercialize
a hydrogen engine generator powered entirely by hydrogen.
As a next-generation, carbon-free power technology, it generates electricity using 100% hydrogen without emitting carbon during operation,
offering a powerful solution for reducing CO₂ emissions.

The First in the World to Commercialize Bio-Based Spandex Hyosung was the first company to commercially introduce plant-based spandex made from industrial corn by replacing fossil fuel-derived materials with corn-based alternatives.

Hyosung became the first in Korea to commercialize Low Power Instrument Transformers (LPIT) and Merging Units (MU) for digital GIS systems.
Certified under IEC standards, this innovation helped reduce reliance
on imports through superior technical competitiveness.

Hyosung TNS developed the world’s first Digital Desk™, a digital branch solution that is transforming banking operations by enabling automated in-branch services.

Hyosung was the first in Korea to commercialize ARMOUR, an advanced asset management solution for substations. Designed to diagnose the condition of various substation facilities in real time, ARMOUR combines cutting-edge technologies such as AI and digital transformation (DX), offering an approach to power equipment management in the era of the Fourth Industrial Revolution.

Hyosung introduced Korea’s first digital kiosk for banking services.
This non-face-to-face financial solution allows customers
to open new accounts and issue cards without visiting a bank branch.

POKETONE™ is a sustainable engineering plastic with excellent wear
and chemical resistance. As it is also non-toxic, its applications are expanding
into various sectors including children’s tableware, construction materials,
automotive parts, household goods, and leisure products.

Since the late 1990s, Hyosung Heavy Industries has been researching
STATCOM technology. In 2006, it developed Korea’s first 345kV 100MVar
model. By 2015, it became the first in Korea and the third globally
to commercialize an MMC (Modular Multi-Level Converter) STATCOM,
applying the latest high-capacity, low-loss technology for grid stability.

The centrifugal charging pump is a core component of nuclear power plants, used to regulate the recirculation flow and concentration of reactor coolant (borated water). Hyosung’s successful development of this pump marked
a significant advancement in Korea’s domestic nuclear technology.

Hyosung’s GIS (245kV and 420kV) was selected as a world-class product by the Ministry of Trade, Industry and Energy and KOTRA. Developed using proprietary technology, the GIS integrates disconnectors, arresters, and circuit breakers into a single compact unit, reducing installation space.

Hyosung’s Creora spandex, Korea’s first domestically produced spandex, achieved the world’s top market share in 2010. Since its launch in 1992,
it has grown into an innovative global brand recognized for superior quality.

Hyosung’s 750kW gear-type wind turbine system, developed entirely
with domestic technology, became the first in Korea to be certified
by Germany’s DEWI-OCC, a global wind power certification body.

Hyosung independently developed TAC film technology and completed
Korea’s first TAC film production facility in Yongyeon, Ulsan.
TAC film is a key material used in LCD displays.

This was the world’s first fiber created from recycled fishing nets.

Hyosung Heavy Industries was the first in Korea and second globally
to develop a 1,100kV GIS using proprietary technology, strengthening
its leadership in the ultra-high voltage power equipment field.

Hyosung Chemical became the first in Asia to develop PP-R pipe products, an affordable, hygienic alternative to metal piping, recognized globally for their durability and long-term performance of over 50 years.

Hyosung Heavy Industries developed the world’s first 800kV 2-break gas-insulated switchgear (GIS), which has been recognized as technologically superior to the existing 4-break systems. It was a milestone that reinforced Hyosung’s global reputation in ultra-high voltage GIS.

In January 1997, Hyosung succeeded in the first-ever mass production of spandex in Korea. Through continued innovation, the Creora brand captured 30% of the global market, positioning Hyosung as the world’s leading spandex manufacturer.

Hyosung was Korea’s first private firm to enter the computer industry.
A dedicated computer division was formed, engineers were sent to Hitachi
for training, and by 1980, a computer production plant was built in Gumi.

Hyosung established Korea’s first private corporate research institute in 1971. Originally focused on synthetic fibers that fueled industrial growth in the 1970s, the R&D Center later expanded into chemical materials and advanced technologies.

In 1969, Hyosung Heavy Industries became the first in Korea to develop
a 154kV ultra-high-voltage transformer. In 1992, it went further to become
the first in Korea, and the sixth in the world, to develop a 765kV transformer,
ushering in a new era for Korea’s domestic power industry.
