Oil-Immersed Transformer — High Power & Cost-Effective Industrial Power Equipment

2026-05-18

1. Product Overview

Although dry-type transformers are popular for safe indoor use, oil-immersed transformers still occupy an irreplaceable position in high-power, outdoor and remote industrial power supply scenarios. Our upgraded S20 series oil-immersed transformers optimize the traditional oil cooling structure, with lower loss, stronger overload resistance and longer service life, meeting the low-cost and high-power demand of overseas industrial users.

2. Competitive Advantages

· 

High Power & Stable Heat Dissipation: Adopt natural oil circulation cooling technology. The internal insulating oil efficiently dissipates heat, supporting long-term high-load operation. It is suitable for high-power power supply demands of heavy industry and mining enterprises.

· 

· 

Low Production Cost & High Cost Performance: Compared with dry-type transformers, oil-immersed transformers have lower unit price and simpler manufacturing process. It is the most economical choice for large-batch procurement of outdoor industrial projects.

· 

· 

High Mechanical Strength: High-purity copper winding and high-permeability silicon steel sheet iron core enhance short-circuit resistance. The product is not easy to deform and damage during long-distance sea transportation and harsh on-site operation.

· 

· 

Upgraded Sealing & Anti-Leakage: Optimized welding process and high-quality sealing accessories effectively reduce oil leakage probability. Equipped with oil storage and pressure relief devices to extend equipment service life.

· 

3. Applicable Scenarios

Widely used in remote mining areas, rural power grid renovation, heavy industrial factories, power plants and other outdoor high-power power distribution occasions. It is especially suitable for regions with sufficient space and low environmental safety restrictions in Africa, Southeast Asia and the Middle East.

4. Factory Strength & Cooperation

Our oil-immersed transformers comply with IEC 60076 international standards and pass CE, RoHS export certifications. We support wholesale bulk orders and spot supply. Professional after-sales engineers provide overseas installation guidance. If you need high-cost-performance industrial transformers, please contact us to get the latest factory ex-factory price.
