Asia Naphthenic Transformer Oil Solutions
Electrical insulating oil can be categorized into two main types based on their composition: mineral insulating oil and synthetic insulating oil. Mineral insulating oil is derived from refined petroleumbased insulating materials. On the other hand, synthetic oils used for cables primarily include dodecylbenzene (commonly used in selfcapacitating oilfilled cables), polybutene (used in steel pipe oilfilled cables), and a limited amount of silicone oil for flameretardant cables. Currently, mineral insulating oil remains the predominant choice, which is why the term "electrical insulating oil" typically refers to mineral insulating oil.

Transformer oil is vital in electrical equipment for providing insulation between charged parts, thereby preventing short circuits. The dielectric constant of air is 1.0, whereas transformer oil has a dielectric constant of 2.25, indicating that its insulating strength is significantly greater than that of air. For instance, a coil of transformer oil exposed to air would quickly be punctured while in operation. However, filling transformer coils with transformer oil enhances their insulating strength, preventing punctures. Furthermore, as the quality of the oil improves, the safety factor of the equipment is also increased.

1. Preparation for Oiling
To decide when to change the transformer oil, consider the transformer's operational status, historical data, and the predetermined maintenance schedule. Typically, transformer oil should be replaced every 3 to 5 years.
Choose the appropriate transformer oil based on the transformer's model and the actual working conditions.
Prepare the necessary tools and equipment for the oil change, such as oil drums, pumps, pipes, filters, filter elements, thermometers, level gauges, cleaning cloths, protective gloves, coveralls, and helmets.
Take necessary safety precautions: Ensure the operator is wearing protective gear and the work area is safe, free from any open flames or smoking.
2. Market Challenges
The price volatility of crude oil significantly influences the transformer oil market. According to the International Energy Agency, the average crude oil price was USD73.6 per barrel in October 2018. However, the price surged to over USD100 per barrel in the first half of 2022. Unpredictable oil price fluctuations can disrupt the oil and gas industry, leading to investment risks in the global transformer oil market. This market relies heavily on mineral oils like naphthenic and paraffinic for transformer applications. As a result, the transformer oil market may face challenges due to the unstable crude oil prices during the forecast period.
