Transformer Industry is Anticipated to Fastest Growing Sector in Asia Pacific

by admin

A transformer is an electrical machine that is designed for transferring electricity from one specific circuit to another with different voltage levels. There are different forms of transformers that are bifurcated based on a couple of factors such as installation location, winding arrangement, the medium utilized in the core, and the working voltage range.

The transformer market revenue is projected to cross USD 80.1 Billion by 2027, transformer industry is anticipated to grow on account of rising infrastructural spending followed by upgradation of existing grid network. Favourable regulatory policies for rural electrification coupled with large scale suburban migration will propel the business growth. Ongoing Refurbishment demand for existing grid infrastructure along with large-scale renewable integration will augment the industry landscape.

Shell core transformer segment is anticipated to grow on account of integration of wide-ranging frequency distribution infrastructure and consistent grid support mechanism. The use of transformers in various industrial applications, surge in adoption of different ratings of transformers in different regions globally, rise in R&D activities and rise in industrialization are driving the growth of the market. Public & private players are investing extensively toward deployment of renewable power sources followed by favourable government incentives and schemes toward installation of solar power transformers will propel the business potential. The world economy is hit by COVID-19 pandemic where, even after re-starting the operations, many regions are facing challenges of restarting their manufacturing capacity and companies are undergoing the effect of shortages in their supply networks. However, increasing electricity demand across the healthcare sector is anticipated to enhance the product installation.

Transformer Market- By Phase

By Phase, Transformer Market is segmented into single phase transformer and 3-phase transformer. Three phase transformers are witnessing significant growth in the market owing to wide applications such as supplying large loads, power transmission of the electrical grids in the power generation and rising implementation in the transmission and distribution sector. As compared to the single phase transformers the three phase transformers are more economical for supplying large loads and large power distribution. The three phase transformers are increasingly used owing to their various advantages like they are smaller and lighter to construct, they have better operating characteristics. The power generated at various generating stations is in three phase nature with voltages ranging from 13.2KV or 22KV which are then used in various end use industries for several applications. Features like high efficiency, space reduction, light weighted and smaller, low cost compared to three units of single phase transformers among others are fueling the growth of the three phase transformer market.

Transformer Oil Market Trends 

Transformer oil  acts  as a cooling and insulating  medium in transformers. This insulating oil not only fills up the pores in the fibrous insulation such as paper, but also the gaps between the turns of the winding and the spacing between the winding and the  tank.  The  oil,  in  addition  to  functioning  as  a dielectric, also serves as a cooling medium and also preserves the  metal parts  internally  by submerging them. There are so many oils used in the transformers right from Mineral oil to vegetable oil. The main purpose of using oil in a transformer is to provide electrical insulation between the various live parts and it also acts as a protective coating layer to prevent oxidation  of the metal surfaces. Another important function of the oil  is to enhance  heat dissipation. Transformer cores and windings get heated  up during  operation  due  to  various power losses. Oil takes heat away from the core and windings  by  the  process  of conduction  and  carries heat to the surrounding tank, which is then radiated out to the atmosphere.  Transformers generate a lot of heat and the heat has to be removed or the copper will  melt  and  lead  to  failure  of the transformer  as  a whole.  Since the beginning  mineral  oil has dominated  the industry but there are certain disadvantages of using it.  Anyone who has been involved  in a transformer oil spill or  leak knows the headache as well as the expense  of  cleanup.  Today,  most  transformers  use insulating and cooling fluids derived from petroleum

crude oil. Industries have little choice but to develop extensive contingency plans and detailed procedures that require training personnel and purchasing special

equipment  to handle  accidental  spills  and  leaks  of transformer fluid. Several recently introduced environmentally  friendly fluids  could be substituted in transformers thereby reducing or eliminating these elaborate procedures. Transformer oil helps in:

– Providing an arc quenching medium .

-It acts like  an  insulation between the windings for which copper losses due to heating reduces.

-It reduces the humming noise created in the transformer resulting in low vibration.

The mineral oil segment is expected to be the fastest-growing segment

The mineral oil segment is estimated to be the fastest-growing during the forecast period 2021-2025

Mineral oil is subdivided into naphthenic oil and paraffinic oil, and a majority of the existing and new transformers manufactured uses mineral oil as the cooling fluid. Mineral oil has low biodegradability and low fire safety potential, which has necessitated the need for other insulating liquids to be used in transformers, reactors, and switchgears installed at high-fire risk areas, such as chemical factories. Mineral oils consist of hydrocarbon components, which usually comes from residual oil fractions of the appropriate viscosity level. In other words, mineral oil is a by-product of petroleum distillation. Naphthenic oil, a subdivision of mineral oil, is more stable in oxidation at different temperatures. In addition, these oils form soluble sludge during the course of operation, which does not affect the transformer’s operational efficiency. Thus, easy availability and the low price of mineral oil compared to other transformer oils are expected to drive the market during the forecast period of 2025.

The growth of this market can be attributed to the growing demand for power in developing countries, such as China and India, and established economies, such as Japan and China. Growing power requirements, along with the upgradation of the aging electrical infrastructure, are expected to result in an increase in the number of substations. This will propel the demand for transformers, reactors, and switchgears, which will boost the demand for transformer oil. Other important factors stimulating transformer oil market share include electrification of rural areas, expansion of power grids and increasing investment in the power sector. However, factors such as volatility in crude oil prices and increasing adoption of dry transformers are expected to hamper the market growth.
