Global Liquid-immersed Transformers Market: Industry Analysts Predict a Surge in Demand for Bio-based Transformer Oils

Renewable energy


The global liquid-immersed transformers market is valued at around 29 billion units and is expected to surpass 25 billion units by 2021, says Technavio.

Technavio has announced its latest market research report on the global liquid-immersed transformers market, under its engineering tools portfolio. This market analysis discusses the major drivers and key emerging trends and offers an analysis of key vendors like ABB, CG, GE, Schneider Electric, and Siemens.

According to Anju Ajaykumar, a lead analyst for engineering tools research at Technavio, “The increase in installation activities regarding new transformers and the replacement of old transformers with new ones is propelling the demand for liquid-immersed transformers in the global market.

The inability of existing networks to meet the demand for power is the driving force behind the ongoing T&D infrastructure renovation in the global market. In Russia, Chelyabenergo, a subsidiary of the utility interregional and regional distribution grid companies (IDGCs), completed its reconstruction work on the 110/10 kV Miass substation in the Urals in 2015. Its activities included the replacement of the major systems and components, including replacing the old 6.3 MVA transformers with new 16 MVA transformers.

Environmentally friendly and more fire-resistant insulating liquids

Several transformer manufacturers in the global market are focusing on their R&D towards the development of transformers that operate on non-mineral transformer insulating liquids. For instance, big players like Siemens have increased its research on the development of alternative transformer insulating liquids as they believe that it is an investment toward a safe and eco-friendlier future.

Increasing popularity of bio-based and naphthenic transformer oil

Bio-based oil is incombustible and non-toxic attributes, which have boosted its use in transformers. The demand for naphthenic oils mainly arises from the automotive and construction industries. Countries worldwide, especially in North America, have started using bio-based transformer oil.
