2025 Transformer Market: Best-Selling Dry-Type and Oil-Immersed Transformer Models
Time：2025-08-19 Auther：ZTelec-www.ztelectransformer.com
In global power systems, dry-type transformers and oil-immersed transformers remain two dominant technologies. With the rise of new energy, data centers, and stricter global efficiency standards, the market in 2025 shows clear trends. This article compares their advantages, applications, and reveals the best-selling transformer models in 2025.
Dry-Type Transformers
Dry-type transformers are rapidly gaining share thanks to oil-free designs, enhanced safety, and advanced monitoring.
Core Advantages: They eliminate fire hazards and pollution risks, reduce lifecycle costs by 30% with no oil maintenance, meet IE4/IE5 efficiency standards with 10%-20% lower losses, and support digital monitoring and remote operation.
Application Scenarios: Widely used in data centers, hospitals, subways, commercial complexes, photovoltaic stations, wind farms, and urban power grid upgrades.
Oil-Immersed Transformers
Oil-immersed transformers remain competitive with cost and capacity advantages.
Core Advantages: 20%-30% lower manufacturing cost compared to dry-type, efficient heat dissipation for high-capacity loads, proven technology with reliable maintenance practices.
Application Scenarios: Popular in rural power grid reconstruction, large industrial sectors (steel, chemical, metallurgy), and conventional power plants.
Transformer Market Trends in 2025
Policy-Driven: Global carbon neutrality and stricter standards (EU Ecodesign, China GB 20052-2025) accelerate adoption of dry-type transformers.
Demand Growth: Data centers and renewable energy push dry-type market share above 55% in 2025, with annual growth of 5%-8% expected.
Technology Breakthroughs: Advances in cooling (nano-coating, intelligent air ducts) and amorphous alloy materials reduce costs by 15%-20% compared to 2020, narrowing the price gap with oil-immersed models.
Best-Selling Transformer Models in 2025
Dry-Type Transformers (10kV-35kV):
SCB15 / SCB18 (Epoxy Resin Cast) – IEC 60076-11 compliant, GB 20052-2023 Level 1 certified, ideal for data centers and commercial projects.
SGB15 (Amorphous Alloy Core) – 70% lower no-load loss, widely adopted in photovoltaic and wind power.
Oil-Immersed Transformers (10kV-35kV):
S13 / S18 (Silicon Steel Core) – 10%-15% lower no-load losses vs. S11, used in rural grids and industrial parks.
SH25 (Amorphous Alloy Oil-Immersed) – Combines low loss with oil cooling, popular in European and American smart grid projects.
By 2025, the transformer market is characterized by dry-type transformers driving growth, supported by policies and demand in emerging sectors, while oil-immersed transformers remain indispensable in traditional and high-capacity applications. For users, the best choice depends on safety, load profile, and budget. The trend is clear: energy-saving, intelligent, and eco-friendly transformers are the mainstream of the future.
