Business Areas

• Manufacturing of Gas Insulated Switchgear and Distribution Equipment: We manufacture and supply 25.8kV-class Gas Insulated Switchgear (GIS) and Load Break Switches (LBS) installed in power plants, substations, and transmission/distribution lines. We produce core protection equipment that guarantees the reliability and safety of power systems.
• R&D on Eco-friendly Insulation Switchgear: To reduce greenhouse gas emissions, we develop epoxy and polymer-based solid insulation technology that replaces SF6 gas. We are researching and commercializing eco-friendly distribution equipment for underground and overhead lines in line with the transition to eco-friendly power grids.
• Control Devices for Power Supply and Development Services: We perform design of switchgear control devices for the protection and control of distribution lines and customized power machinery development services. We supply specialized electrical control solutions such as multi-circuit breakers and fault passage indicators.

Products

• Gas Insulated Switchgear (GIS / CGIS): This is a 25.8kV-class core switching device that prevents the expansion of fault sections by quickly and safely cutting off excessive fault currents when an abnormality occurs in the power system. It provides high stability that meets the substation standards of the Korea Electric Power Corporation.
• Epoxy/Polymer Solid Insulated Load Break Switch: This is an eco-friendly distribution switch for underground and overhead lines that reduces greenhouse gases by applying a solid insulation medium instead of SF6 gas. It is supplied to domestic and international distribution lines due to its excellent insulation performance and durability.
• Solid Insulated Fault Passage Indicator (EFI): This is a protection device that supports uninterrupted power supply by automatically detecting fault currents in the line and isolating the accident section. It features a compact design and the application of eco-friendly insulation materials.

Special Notes

• Manufacturing system based on 100% in-house technology: The entire process, from product design and testing to the production of finished goods, is carried out through in-house engineering. Based on excellent core technologies, we respond quickly to market demands and specification changes.
• Proven reliability through supply to Korea Electric Power Corporation: Having passed the strict quality and performance test standards of the Korea Electric Power Corporation, we have achieved numerous annual unit price supply contracts and substation project orders. We possess product quality and delivery records at the level of public infrastructure.
• Eco-friendly R&D capabilities based on a corporate research institute: Centered on our corporate research institute, we have executed continuous R&D investments and obtained patents and INNO-BIZ certification. We possess the technological capability to proactively respond to the trend of eco-friendly power facilities.

Recruitment Information

• Main Hiring Positions: Electrical equipment assembly and wiring production staff, product inspection and quality control, power equipment design and development
• Benefits: 4 major social insurance, severance pay, 5-day work week, lunch provided

💡 A Word from JOBPLOY
Due to the nature of the work environment manufacturing heavy electrical equipment and distribution switchgear, delicate and precise manual work such as component assembly and electrical wiring is the main task. As heavy object handling and electrical testing processes may be involved, basic safety protective gear must be worn within the workplace and on-site safety rules must be strictly followed. It is recommended to familiarize yourself with basic Korean terms related to electrical assembly in advance to accurately understand the drawings and instructions of the manager.
