오일 절연 개폐장치(OIS) 시장 기회, 성장 촉진요인, 산업 동향 분석, 예측(2025-2034년)

The Global Oil Insulated Switchgear Market reached USD 9.4 billion in 2024 and is expected to grow at a CAGR of 6.5% from 2025 to 2034. This growth is driven by the rising need for efficient and reliable power distribution systems across various sectors. OIS provides enhanced insulation and robust performance, even under extreme conditions, making it a preferred choice for utilities, substations, and industrial operations. Its ability to manage high voltages further cements its importance in ensuring stable power supply in critical applications.

The push toward modernizing electrical grids and expanding infrastructure, particularly in developing economies, is significantly boosting the adoption of OIS. Integration into distribution networks has become a priority to enhance reliability and reduce downtime. Technological advancements in oil insulation have improved safety and environmental compatibility, further supporting market expansion. Moreover, the integration of renewable energy systems and the replacement of outdated equipment in mature markets are driving demand for advanced OIS solutions.

By voltage, the low-voltage segment is set to generate USD 9.1 billion by 2034, fueled by growing requirements for safe and efficient electrical distribution in residential, commercial, and industrial settings. Low-voltage OIS is crucial for protecting electrical systems against faults like short circuits and overloads, ensuring operational safety and continuity. Rapid urbanization and infrastructure development, especially in emerging markets, combined with global industrial growth, are creating significant opportunities for this segment.

In terms of current, the AC segment is projected to grow at a CAGR of 6.3% during 2025-2034. The continued dominance of AC power in global electricity use underpins this growth. AC OIS systems are integral to power distribution across grids, infrastructure, and residential setups, where consistent and efficient electricity delivery is paramount. The increasing adoption in industrial automation and modern electrical networks further supports this segment's expansion.

U.S. oil insulated switchgear market is expected to reach USD 1.2 billion by 2034, driven by efforts to modernize aging electrical infrastructure. Upgrading obsolete systems with advanced OIS technologies has become a key focus for utilities and industries seeking reliable and efficient power solutions. This transition aligns with the growing emphasis on enhancing grid stability and reducing operational risks, particularly in sectors that rely on uninterrupted power for seamless operations.
