Synthetic Electrical Transformer Oil Solutions
Synthetic Electrical Transformer Oil Solutions
Extracted directly from natural petroleum, mineral oil serves as the primary engineering liquid dielectric in transformers, offering superior insulation while playing a pivotal role in heat dissipation and arc suppression during transformer operations. In the presence of an arc, the oil swiftly cools it, leading to its extinguishment. Furthermore, it efficiently removes heat and gas products from the discharge area, rapidly decreasing the voltage level in the discharge field, enabling effective discharge management.
Product Details：Insulating oils have a variety of advantages, such as high dielectric strength, high flash point, low viscosity, free of organic acids, alkalis and corrosive sulfur, good anti-emulsification properties, no precipitation of slag under normal operating conditions, the arc product can be quickly precipitated, and a low pour point and so on. These advantages enable the insulating oil to play an excellent insulating and cooling role in electric equipment.

1. Transformer Oil Service Life
In most cases, transformer oil should be replaced every 5 to 10 years. However, this is just a rough estimate, and the actual replacement period must be assessed based on the individual conditions of the transformer.
To summarize, the service life of transformer oil is a complicated issue impacted by multiple factors. To ensure the transformer operates effectively and to extend its lifespan, regular inspections and evaluations of the transformer oil are recommended, with timely replacements based on actual needs.
2. Factors Affecting Service Life
Transformer Load: Sustained high loads on a transformer can accelerate the aging of the oil, resulting in a shorter operational life. Therefore, it is essential to manage the load on the transformer wisely to enhance the oil's lifespan.
Oil Quality: The longevity of transformer oil is heavily impacted by its quality. Oils of high quality provide better thermal stability and anti-aging characteristics, which can extend their service life. Conversely, poor-quality oils may degrade quickly, leading to a reduced lifespan.
