Aromatic Transformer Oil For Improved Efficiency

Transformer oil, a synthetic mineral oil, undergoes a meticulous process of distillation and refinement from natural petroleum. Its primary chemical constituent, naphthenic hydrocarbon, comprises approximately 80% of its total makeup, with the remaining portion largely consisting of aromatic hydrocarbons and alkanes. Boasting remarkable stability in its physical attributes, transformer oil exhibits a relative density of 0.895, a freezing point typically under 45°C, and a flash point no lower than 136°C.

1. Transformer Oil Service Life

Under normal circumstances, the replacement cycle of transformer oil is between 5 to 10 years. However, please note that this is only a rough reference range, and the actual replacement cycle needs to be assessed based on the specific conditions of the transformer.

In summary, the service life of transformer oil is a complex issue influenced by various factors. To ensure the normal operation of the transformer and extend its lifespan, it is recommended to regularly check and evaluate the transformer oil and replace it in a timely manner based on actual conditions.


2. Factors Affecting Service Life

Transformer load: If the transformer is under high load for a long time, the aging speed of the oil may be accelerated, resulting in shorter service life. Therefore, reasonable control of transformer load is the key to extend the service life of oil.

Oil quality: the quality of transformer oil is an important factor affecting its service life. High-quality transformer oil has better thermal stability and anti-aging properties, which can extend the service life. On the contrary, poor quality oil may be used in the process of rapid aging, resulting in shortened service life.

Customer Testimonials

"The industrial lubricating oil from Haikun is simply the best. It performs well and is priced reasonably. Plus, the packaging is secure. – Pakistan, Mohammad Ali"

Coal-Based Transformer Oil ,PCB-Free Transformer Oil ,REACH SVHC Compliance 

The earth keeps track of every harm done to it—PCB-laden oil stains once left soil silent for decades, but we’ve chosen to turn transformer oil into a "gentle energy carrier." Free from PCB threats and the weight of slow degradation, it seeps into the soil like spring rain. Even if accidents happen now and then, it dissolves quietly in nature, never disrupting a plant’s growth or clouding a single drop of water. In this container of oil, there’s the purest respect for the earth.
