Because of its high efficiency, easy availability, and its useful chemical properties such as a good pour point at low temperature and exceptional thermal cooling capacity, naphthenic mineral oil has long been the most preferred transformer oil. This is because of its high efficiency, easy availability, and its useful chemical properties. Because of its remarkable resistance to oxidation, the use of paraffinic mineral oil has been increasingly widespread during the past several years. However, both the paraffinic and naphthenic varieties of mineral oil are products of extremely refined, purified, and processed petroleum, and as a result, they are extremely resistant to biodegradation. The biodegradability of the mineral oil ranges from 0 to 40 percent, and it is derived from a resource that does not replenish itself. Both the developed and the developing economies throughout the world are currently undergoing a shift toward the adoption of technology that are environmentally friendly and green. This shift might prove to be a barrier to the widespread use of mineral-based transformer oils in the not-too-distant future, and it could act as a constraint on the market for mineral oil in the long run.
Commerce in electricity across international borders has been picking up steam in recent years, and the number of economies that are taking part in this trade has skyrocketed over the course of the last several decades. For instance, the European Union (EU) is making preparations to construct a pan-European power grid while simultaneously strengthening the power systems of each individual country. Recent discussions at the Indian Energy Exchange (IEX) have focused on the possibility of establishing an integrated power market for the South Asian region. This would be accomplished by facilitating the trade of electricity across international borders between countries such as Myanmar, Bhutan, Sri Lanka, Bangladesh, and Nepal. In the next years, these new advancements are anticipated to result in the extension of the grid network as well as the installation of new transmission lines. This will lead to an increase in the demand for transformers and switchgear, as well as for transformer oils.
