Since its establishment in 2012, the company has maintained stable growth by supplying contract manufacturing services for large transformer windings and core assembly to Hyundai Heavy Industries. Based on high-efficiency power conversion technology, the company supplies essential power infrastructure solutions to the Korea Electric Power Corporation (KEPCO) and various industrial plants.

Business sectors

• Manufacturing and Supply of Transformers for Power Grids: We directly design, manufacture, and supply oil-immersed transformers and molded transformers—the core of the national power infrastructure—to the power system. By applying low-loss designs that maximize energy transmission efficiency, we meet the stringent specifications of public institutions.
• Manufacturing of High-Capacity Transformer Windings: In response to the rapid growth of global electricity demand and the transformer market, we are constructing a new intelligent factory for the manufacturing of windings for high-capacity transformers (154 kV to 400 kV). This contributes to enhancing competitiveness by modernizing the production system for manufacturing voltage-regulating coils.

Products

• High-Efficiency Power and Distribution Transformers: We manufacture high-efficiency transformers used to step up or step down voltage in power systems. These are critical equipment deployed in power plants, industrial sites, and large-scale power infrastructure.
• Transformer Coils and Iron Cores: We specialize in the manufacturing of coils (windings) and iron cores, the core components of transformers. We supply high-quality transformer parts through precise winding operations and batch assembly technology.

Special Features

• HD Hyundai Electric Key Partner: As a key partner of HD Hyundai Electric, we have secured a stable business foundation by performing winding and batch assembly, which are core processes for power transformers. This is an important factor demonstrating the company's reliability and technological capabilities.
• Proprietary Technological Capabilities and R&D: Based on proprietary core technologies, we have secured a differentiated competitive advantage in the relevant field and are expanding our technology portfolio through continuous investment in research and development. Our expertise is verified by our patent portfolio and project execution history.
• Advanced Production through the Adoption of Smart Factories: We are upgrading our production system by introducing an intelligent factory (Smart Factory) fully equipped with temperature and humidity control functions. Through this, we plan to strengthen our capacity to produce high-quality products and leap forward as the nation's leading specialized company in winding component processing.

Job Information

• Main Recruitment Positions: We expect to primarily recruit for production roles related to transformer manufacturing and processing, winding operations, and batch assembly. We plan to prioritize the hiring of Ulsan residents when recruiting for factory operations.
• Benefits: We provide the four major insurances, including National Pension, Health Insurance, Employment Insurance, and Industrial Accident Insurance.
