Product Lineup

  • SF6-Free GIS

    HD Hyundai Electric was the first in Korea to develop SF6-Free GIS using fully proprietary technology. This product replaces SF6 (sulfur hexafluoride), which has a Global Warming Potential (GWP) 23,900 times greater than CO2, with a C4F7N+CO2 gas mixture, reducing greenhouse gas emissions by approximately 99% compared to conventional products. In April 2021, based on our longstanding technological expertise, we successfully developed Korea’s first 170kV 50kA 4,000A GIS using Novec mixed gas (C4F7N+CO2). Following this, we completed the development of a 145kV 40kA 3,150A GIS in December 2023. In June 2024, we also completed the development of a 72.5kV 31.5kA 2,500A GIS, which uses dry air and vacuum interrupter technology with no greenhouse gas application. We will continue to expand our lineup of SF6-Free GIS across various voltage levels to meet the growing market demand for carbon neutral solutions.
  • Natural Ester/Synthetic Oil-immersed Power Transformer

    HD Hyundai Electric has developed transformers that use flame-retardant, biodegradable, and nontoxic insulating oils (vegetable or synthetic), helping prevent serious environmental pollution in the event of oil leakage. These products integrate HD Hyundai Electric’s core technologies—including advanced insulation and cooling designs—and support enhanced explosionproof performance through the application of DPRS (Dynamic Pressure Resistant System), delivering superior safety and operational performance.
  • Engine Mounted Generator

    HD Hyundai Electric’s Engine Mounted Generator (EMG) makes more efficient use of onboard space than conventional shaft generators. Moreover, it enhances the overall energy efficiency of the ship’s propulsion system, resulting in approximately 2–3% lower fuel consumption and 4–5% reduction in carbon emissions.
  • Permanent Magnet Shaft Generator

    In November 2021, HD Hyundai Electric became the first company in Korea to successfully develop a 2 MW large-capacity permanent magnet shaft generator using proprietary technology, achieving localization of a product that had previously been entirely dependent on imports. The rotor of this generator features high-performance neodymium permanent magnets, delivering up to 3% higher generation efficiency than conventional methods, while its compact and lightweight design ensures higher power density compared to induction-type generators. By utilizing the rotational energy of large propulsion engines for electricity generation, the system enhances energy efficiency and reduces fuel costs. It also cuts carbon emissions by approximately 3%, improving the Energy Efficiency Design Index (EEDI)1) and enabling proactive compliance with global environmental regulations.

    1) EEDI (Energy Efficiency Design Index): The amount of CO2 emitted when a ship transports one ton of cargo over one nautical mile (unit: g/ton·mile)

  • IE4 LV Motor (Super Premium Efficiency Low-Voltage Motor)

    In July 2023, the European Union raised the minimum efficiency standard for electric motors from the Premium Class (IE3: International Energy Class) to the Super Premium Class (IE4). In response, Korea is expected to adopt the same regulation starting in 2026. HD Hyundai Electric has developed IE4 motors that are more than 1.1% more efficient than IE3 models, proactively responding to the rising demand for IE4 low-voltage motors in developed countries. Leveraging its long-accumulated technological expertise, the company will continue to expand its lineup of high-efficiency, high-output electric motors.
  • Dry-air switchgear (E-GIS)

    In 2015, HD Hyundai Electric signed a business agreement with Korea Electric Power Corporation (KEPCO) and developed switchgear that employs dry air, with a Global Warming Potential (GWP) below 1, as the insulating medium, replacing SF6, a greenhouse gas subject to regulation. Responding to the growing demand for environmentally sustainable switchgear, the company successfully developed and supplied the 25.8kV E-GIS, achieving Korea’s first export of such a product in 2020. HD Hyundai Electric is further striving to strengthen its competitiveness in environmentally sustainable products by securing core technologies and commercializing various alternative insulating media in addition to dry air.
