Its major work in transformers is to offer electrical insulation between several live parts while also serving as a protective layer coating to prevent oxidation of metal surfaces. To address ecological concerns & economic expense better alternatives to transformer oils including soybean oil, palm kernel oil, & coconut oil have been figured out & are easily available in nations such as India, Malaysia, & Sri Lanka, etc.
Opportunities in the Transformer Oil Market are growing as global demand for energy infrastructure rises. With electrical grids expanding and the shift to renewable energy, the need for reliable transformer oil is stronger than ever. Additionally, innovations in eco-friendly and fire-resistant oils open up exciting new possibilities for companies to meet evolving industry needs. The increasing adoption of advanced
switchgear monitoring systems also complements the rising demand for high-quality transformer oils.
Transformer oil plays two important functions in transformers: suppressing arcing & dissipating the heat produced inside the transformers. It also makes sure that the core & windings of transformers are properly dipped for better cooling & insulation. An important feature of insulating oil is its capability to avoid oxidation of the paper insulation made out of cellulose. The dielectric strength of transformer oil, also known as the breakdown voltage, is a vital parameter.
A low breakdown voltage value shows the moisture content & conducting substance’s presence in the oil. For its dielectric strength & electrical properties, mineral-based oils, are mostly employed in several transformers.
Dielectric insulating fluid is an important part present in every power transformer &
distribution transformer, providing better electrical resistance & effective cooling for the transformer. Bio-based transformer oils are anticipated to record the highest growth by 2032 because of their better fire resistance & non-toxic features, making them more environmentally friendly.
Recent months have witnessed an exciting movement toward more eco-friendly and high-performance transformer oils. As environmental concerns rise, biodegradable, fireproof, non-toxic oils are becoming more and more sought-after among manufacturers looking to innovate for market needs while meeting global regulatory standards.
As per ec.europa.eu In 2022, the EU’s crude oil production reached its lowest point at 16.3 million tonnes, a significant decline from its peak of 41.7 million tonnes in 2004. Despite rising oil prices due to the Russian invasion of Ukraine, production continued to decrease. Italy, Denmark, and Romania were the leading producers in 2022, contributing 4.5 Mt, 3.2 Mt, and 3.0 Mt, respectively.
Norway, a major non-EU oil producer, saw its production peak in 2001 at 157.6 million tonnes. After a decline, production reached 84 million tonnes in 2022. EU candidate countries like Turkey, Serbia, and Albania produced a combined total of nearly 5 million tonnes in 2022, contributing on a much smaller scale.
Crude oil imports to the EU in 2022 amounted to 479.6 million tonnes, marking a 7.4 percentage point increase from 2021. Imports from Russia decreased significantly by 24.6 million tonnes due to the REPowerEU plan, while imports from Saudi Arabia, the U.S., and Norway rose sharply, compensating for the loss of Russian oil.
