Bellows for Transformer
Bellows for transformer mainly used in the oil conservator of transformer. The external corrugated oil conservator use advanced super flexible stainless steel corrugated compensator as the compensating component and sealing and isolation component, in completely air and moisture isolated condition, to compensate the volume of transformer’s insulating oil. Bellows for transformer just like a gasbag whose inner part connecting to the air, place it in insulating oil, the oil storage box connect with transformer oil box through bottom connector. The volume change of insulating oil would make bellows flex, so that to change the volume of oil box and compensate volume change of insulating oil. Bellows for transformer mainly used to compensate axial displacement and a few lateral displacement, also reduce shock and noise, has advantages of easy installation, simple design and low cost. Bellows for transformer has been widely used in electric power, petroleum and chemical engineering industries.
Product features of bellows for transformer:
- Strong external pressure resistant ability.
- Low cost.
- Easy to install.
- Low temperature resistance, shock resistant.
- Good chemical stability.
