Transformer Oil

Transformer Oil

Novvi XFo Transformer Oil is the first drop-in compatible, environmentally friendly transformer fluid on the market. Novvi XFo exceeds ASTM D-3487 and IEC 60296 standards for mineral insulating oil used in transformers and switchgears, while delivering operational benefits that extend well beyond mineral oil standards.

Improved Efficiency Plus Sustainability

Novvi XFo provides best-in-class heat transfer capabilities, which enables the most efficient operation, and allows more power throughput and higher equipment power ratings. Novvi XFo also has excellent dielectric strength, minimizing power losses. Combining these features leads to improved operating cost.  Novvi XFo is also biodegradable, renewable, and nontoxic, eliminating the need to compromise between performance and environmental responsibility. It is available to utilities and transformer OEMs, as well as to resellers for private labeling.

Longer Equipment Life

While transformer oil is a fraction of the initial equipment investment, it has a major impact on a transformer’s total lifetime, depending on its heat transfer and electrical insulation performance.

Heat Transfer:

A fluid’s heat transfer capability affects operating cost through power losses and insulating paper degradation, which impacts transformer life expectancy. Novvi XFo offers excellent heat transfer capabilities, enabling heat to be removed from the windings and transformer to transmit more power at a given operating temperature. Novvi XFo also has high oxidation resistance, which reduces sludge creation.

Electrical Insulation:

Novvi XFo has a low viscosity and a pour point of -57° F, comparable to mineral oil fluids. This eliminates gel formation and the need to heat the fluid before a restart. Because Novvi XFo is a hydrocarbon, it can also be restored to its natural state through standard mineral oil degassing and other reclamation processes, allowing it be reused following water, acid, or particulate contamination.

Product Comparison

There are several environmentally friendly dielectric fluids on the market. When deciding which to use, it’s important to consider how they differ from traditional mineral oils, as these differences can cause major challenges for transformer engineers, owners, and operators. Novvi XFo is compared to mineral oil-based transformer oil and a commercially available vegetable-oil based transformer oil in the chart table below.
