Corrugated Conservator

The internal oil-type corrugated metal conservator is a third-generation fully sealed device for oil-immersed transformers. Using a stainless steel corrugated core, it compensates for oil volume changes caused by temperature fluctuations through vertical core movement. It offers excellent sealing, isolating air and moisture, preventing oil oxidation, and extending transformer life.
