S-M Series Fully Sealed Oil-Immersed Transformer

Product Overview

TiraThai, a specialized sub-brand of Jinguan Electric dedicated to transformer and electrical equipment innovations, proudly introduces the S-M Series Fully Sealed Oil-Immersed Transformers. These advanced units are suitable for AC 50Hz power systems with rated working voltage of 20kV and below, serving as distribution transformers in petroleum, metallurgy, chemical, textile, light industry, and other enterprises or locations with significant dust. Developed on the basis of the new S9 series structural design, the S-M series emphasizes product reliability and performance optimization. By readjusting loss coefficients and structures to align design values with real-world performance, and rationally proportioning copper and iron for low material costs and reasonable structure, these transformers deliver efficient, durable power distribution.

Jinguan Electric, founded in 1979 as a high-tech enterprise in Nanyang City, Henan Province, China, has evolved from pioneering arrester manufacturing to a global leader in high-voltage transmission and distribution equipment. Embracing Industry 4.0 principles, Jinguan Electric drives core competitiveness through continuous innovation, with TiraThai serving as its premier brand for fully sealed oil-immersed transformer solutions. This sub-brand channels Jinguan Electric's expertise into customizable S-M series transformers that prioritize energy savings, environmental protection, and adaptability, complying with international standards such as IEC 60076, GB 1094, and IEEE C57.12.10. Certified by UL, CUL, CCC, CQC, CTQC, CE, and SGS, these units uphold ISO9001 (quality), ISO14001 (environmental), and ISO45001 (health & safety) management systems, ensuring superior performance in dusty or challenging environments.

The S-M series features no oil conservator, with a tank cover equipped with a trinity device for oil filling, level indication, and pressure release. Vacuum oil filling during packaging removes moisture completely, and sealing prevents air contact, effectively slowing oil aging and eliminating the need for regular oil sampling or replacement over the normal service life. The corrugated fin oil tank provides cooling and a "breathing" function to compensate for oil volume changes due to temperature fluctuations. TiraThai's philosophy—"dig 100 meters deep in 1 meter of space"—reflects Jinguan Electric's commitment to precision, delivering compact, reliable transformers that enhance power distribution efficiency for global industrial needs.

Transformer Model: S-M Series Rated Voltage: ≤20kV AC Frequency: 50/60Hz

This optimized design makes TiraThai's S-M Series Fully Sealed Oil-Immersed Transformers a cornerstone for cost-effective, resilient power in dusty environments.

Key Features and Engineering Excellence

TiraThai's S-M Series Fully Sealed Oil-Immersed Transformers are engineered for reliability and efficiency, featuring a fully sealed design that eliminates the oil conservator and integrates a trinity device on the tank cover for oil filling, level monitoring, and pressure release. The vacuum oil filling process during packaging removes all moisture, and the sealed structure prevents oxygen and water ingress, effectively retarding oil and material aging—eliminating the need for routine oil sampling or replacement throughout the service life.

The corrugated fin oil tank serves dual purposes: as a radiator for effective cooling and as a flexible "breathing" component that compensates for oil volume variations due to temperature changes, enhancing overall thermal management. Based on the S9 series, the design readjusts loss coefficients and structures to better align theoretical values with real-world performance, while optimizing the copper-iron ratio for low material costs and a rational, compact structure. This results in reduced no-load and load losses, improved economic operation, and strong adaptability to dusty or harsh environments.

Jinguan Electric's automated production—featuring precision core stacking, vacuum oil-filling, and AI-driven inspections—guarantees defect-free assembly, with customizable enclosures (IP54 rated) for weather and dust resistance. Compared to unsealed models, TiraThai S-M units extend lifespan to over 30 years and reduce maintenance by 50%, with low noise (under 55dB) suiting urban-industrial settings. Optional features like on-load tap changers (OLTC) and integrated monitoring enable smart integration.

These features not only meet but exceed IEC 60076 and GB 1094 standards, providing users with a transformer that balances cost, performance, and durability.
