CVT Bellow — Flexible Bellows for Transformer Oil Expansion
CVT Bellows are specially engineered expansion components designed to accommodate thermal expansion and contraction in oil-filled systems such as current transformers (CVTs). These bellows help maintain stable oil levels, preserve structural integrity, and ensure efficient performance even under temperature fluctuations.
Available in a wide range of specifications, Flexatherm’s CVT bellows are durable, corrosion-resistant, and built to withstand demanding industrial conditions at competitive market prices.
What Is a CVT Bellow?
A CVT bellow is a flexible, corrugated mechanical element that expands and contracts in response to changes in oil temperature. As transformer oil heats up, it expands — and the CVT bellow flexes outward to absorb this movement. When the oil cools and contracts, the bellow compresses back to its original shape, helping maintain the correct oil level and preventing stress on tanks, seals, and piping.
Key Features & Benefits
✔ Accommodates Thermal Expansion
CVT bellows efficiently absorb dimensional changes in transformer oil systems caused by temperature variations, protecting equipment from stress and leakage.
✔ Corrosion & Rust Resistance
Manufactured from corrosion-resistant materials, these bellows are suitable for long-term use in outdoor and industrial environments.
✔ Durable & Long-Lasting
Flexatherm CVT bellows are engineered for reliability, ensuring consistent performance through repeated expansion and compression cycles.
✔ Wide Range of Specifications
Available in multiple sizes and configurations to meet diverse system requirements and bulk industrial needs.
Applications
CVT bellows are ideal for applications where oil thermal expansion must be managed reliably, such as:
-
Current Transformer Oil Tanks — To balance oil volume changes.
-
Power Transformers — To protect seals, gaskets, and structural parts exposed to oil expansion.
-
Industrial Oil-Filled Equipment — Where temperature changes can cause significant oil movement.
