SH Power Rotary Transformers offer full lifecycle support, covering key solution design, model optimization, and on-site commissioning—all delivered by our highly experienced technical team. We provide precisely tailored solutions for a wide range of applications to ensure highly efficient operation and maximum energy savings.
This product complies with the regulations of GB/T 1094 (Power Transformers), GB/T 6451 (Technical Parameters and Requirements for Oil-immersed Power Transformers), and GB 20052 (Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Power Transformers). In actual production, the material grade of the core shall not be lower than the requirements specified in the engineering drawings.
The product utilizes a hermetically sealed corrugated steel tank structure (or fully enclosed circular steel tank structure), which completely isolates the transformer oil from the surrounding air. This prevents the oil from absorbing moisture from the atmosphere and degrading its dielectric strength. Furthermore, by preventing oxygen from entering the tank, it mitigates the aging of insulation materials, thereby extending the service life of the equipment and enhancing its social and environmental benefits.

Product Features
Long Service Life: The transformer oil tank adopts a fully enclosed structure, with the tank connected to the tank edges by bolts or welding, preventing the transformer oil from being exposed to air and thus extending its service life.
High Operation: The parts and components related to the tank sealing have been improved to enhance their reliability, and the technology has been refined to ensure sealing reliability.
Compact Appearance: The SM series transformer oil tank is equipped with a corrugated plate. When the oil temperature changes, the corrugated plate expands or contracts, equivalent to the same low pressure action as the oil tank. The corrugated plate is aesthetically pleasing and compact.
The product portfolio includes oil-immersed, dry-type, and packaged substation solutions, satisfying all voltage levels and application requirements.
Manufactured with high-grade premium silicon steel and superior insulation systems, our products feature low no-load and load losses, delivering significant energy savings.
