Transformer air cells, also known as conservator bladders or diaphragms, are critical components used in power transformers to separate insulating oil from the atmosphere. Installed inside conservator tanks, air cells act as a flexible barrier that expands and contracts with temperature changes, preventing moisture, oxygen, and contaminants from entering the transformer oil. Parts Super Center supplies OEM and replacement air cells for power transformers designed for utility, substation, and industrial applications. Our inventory supports legacy transformer systems from leading manufacturers such as GE, ABB, Westinghouse, and Eaton, helping maintenance teams extend equipment life and maintain system reliability.
Available air cell solutions include:
- Transformer conservator air cells and bladders
- Diaphragms for oil preservation systems
- Air cell repair kits and replacement components
- Custom-fit solutions for legacy transformer models
Air cells play a key role in reducing oxidation, preventing condensation, and protecting transformer insulation systems from aging and failure. Â By maintaining a sealed environment, they help improve dielectric performance and reduce maintenance requirements in high-voltage systems.
Parts Super Center supports sourcing by OEM part number, specifications, and drawings, ensuring accurate fit and reliable performance. Whether you are performing routine maintenance or replacing a failed conservator bladder, our team provides technical expertise and access to hard-to-find transformer components. Common applications include power transformer conservator systems, oil preservation systems, and high-voltage substation equipment.
