HD Hyundai Electric Debuts the New Circuit Breakers in Finland

— September 17, 2025 — Autos
HD Hyundai Electric has secured a new contract in Finland to supply 14 units of its eco-friendly 145kV gas-insulated switchgear (GIS). GIS systems are high-voltage circuit breakers that utilize gas for insulation, providing a more compact and efficient setup compared to air-based systems.

Unlike traditional models that rely on sulfur hexafluoride (SF₆), a greenhouse gas thousands of times more harmful than CO₂, Hyundai’s switchgear uses safer alternatives like fluoronitrile (C4-FN) or CO₂ mixtures. The company, the first in Korea to develop this type of eco-friendly circuit breaker, views Europe’s growing demand for sustainable power equipment as a significant opportunity to expand its market presence.

“[...] While maintaining stable high-voltage circuit breaker business in existing markets such as the Middle East and the United States, we will accelerate our efforts to penetrate the eco-friendly high-voltage circuit breaker market, especially in Europe," said a company official.
