Extend the Lifetime of Transformer Oil with Xtendra BHT
Transformer oils are critical to the long-term performance and reliability of industrial electrical power systems. As insulating fluids, transformer oils function as a dielectric medium and coolant for high-voltage systems. Over the lifetime of the electrical power systems, due to exposure to oxidation and thermal degradation, transformer oil can compromise performance and accelerate aging.
What Is Xtendra BHT?
Camlin Fine Sciences Xtendra BHT (butylated hydroxytoluene) is a hindered phenolic antioxidant additive with high purity and thermal stability that inhibits oxidative degradation in hydrocarbon-based systems.
Why Antioxidants Matter in Transformer Oil
In oilfield wet transformers, transformer oils are critical for insulating, suppressing corona discharge and arcing, and cooling the transformer. Oil-filled transformers are constantly exposed to extreme temperatures and oxygen over extended operational periods. Without antioxidant stabilization, this insulating oil’s exposure creates oxidative chain reactions forming acid, sludge, and peroxides that can result in electrical breakdown, insulation failure, and increased viscosity. Xtendra BHT breaks these oxidation chains prior to this transformation, allowing for reduced byproduct formation and extending the insulating oil’s lifetime performance.
