Brand:S9
The S9 series oil-immersed transformers, as our company's classic product, exhibit slightly lower energy efficiency compared to the upgraded S11 series (with no-load losses approximately 10% higher than the S11 series), yet they offer more economical pricing. Taking the 750 kVA transformer as an example, the S9 series costs 20%-30% less than its S11 counterpart of equivalent capacity. This series utilizes cold-rolled silicon steel sheets and high-quality oxygen-free copper wire windings, with structural reliability proven through years of market validation. Particularly suited for cost-sensitive power distribution scenarios demanding high stability, the S9 series has maintained widespread application in industrial/mining facilities and civil power supply since its initial release in the early 2000s. More commonly used in industry are 750KVA,1000 kVA oil filled transformer.

1. The iron corn making method that adopts ladder type three grade connection.
2. The tank is square, and the radiator modality has ripple type, patch type, pipe type.Customer can choose freely.
3. The reactor body positioning structure to adapt to long-distance transport.
4. The oil exhibits high chemical stability. When combined with a breather (moisture absorber) and a sealing system, it effectively reduces oxidation and moisture ingress, extending the maintenance cycle to 5-10 years.
5. Configurable with a moisture-proof, dustproof, and salt spray resistant (IP55 or higher) housing.
