What ILJIN Electric does

ILJIN Electric is a South Korean publicly listed manufacturer (KRX:103590) headquartered in Hwaseong, Gyeonggi-do, operating across four divisions under a "Total Energy Solution Provider" positioning. The Heavy Electric Division manufactures UHV power transformers, SF6 gas-insulated special transformers, shunt reactors, gas-insulated switchgear (GIS), EHV circuit breakers, and integrated substation solutions for utilities and transmission system operators. The Cable Division produces extra-high-voltage transmission cables, power distribution cables, and power grid infrastructure solutions with full connection, laying, and installation services, while the Materials Division supplies SCR and aluminium ROD inputs to cable manufacturers. The Energy Solution Division complements the legacy hardware portfolio with Energy Storage Systems (ESS), Grid-Forming Modules (GFM), and Microgrid solutions for renewable integration and grid stability.

The company serves power utilities, transmission system operators, data center developers, and international infrastructure customers through a direct enterprise B2B sales motion. Revenue is generated primarily through project-based hardware sales of heavy electrical equipment, cables, and energy solutions, with international project contracts (e.g., a USD 333.2 million US high-voltage equipment deal, a 62.1 billion won Malaysia UHV cable contract, and an USD 88 million Canada data center transformer deal) representing a growing share of the order book. Pricing is negotiated on a project basis and not publicly disclosed.

ILJIN Electric is part of the ILJIN Group governed by ILJIN Holdings, with the ILJIN brand centrally managed and shared across affiliates including ILJIN Diamond, Alpinion Medical Systems, JTV, and ILJIN Hysolus. The company operates multi-plant manufacturing capacity (Hwaseong Plant 1 and Plant 2), with Plant 2 expansion specifically driving transformer output to support overseas orders growth. In 2025–2026 the company reported record profit and sales driven by North American grid replacement demand, AI data center buildouts, and Southeast Asian transmission infrastructure projects.
