Power Transformer Market Share

Shell core segment dominates the market, driven by its cost-effectiveness, design flexibility, and performance characteristics

Shell core transformers hold substantial share of the market as these transformers feature a square or rectangular cross-sectional core, which makes them more cost-effective to manufacture. Shell core transformers are widely used in low-voltage and high-output applications due to their efficient cooling system, design flexibility, high seismic withstanding ability, and high short-circuit strength.

Closed core transformers, on the other hand, are a type of power transformer that feature a closed magnetic circuit. They are known for their efficient design and ability to handle high overloads and short-circuit currents. As per power transformer market analysis, closed core transformers are commonly used in applications where space is limited, such as in urban areas. Berry core transformers are another type of power transformer that feature a circular cross-section. They are known for their efficient control of leakage magnetic flux and are often used in electronic and low-voltage power circuits.

Oil insulated transformers are highly used due to their excellent dielectric strength

Oil-based insulation occupies a significant portion of the power transformer market share as it provides better thermal stability compared to other insulation materials and prevents the risk of overheating. Its excellent dielectric strength also makes it tolerable to high voltages and minimises the possibility of damage due to power overload. Furthermore, the rising trend of sustainability has fuelled the demand for eco-friendly oils such as ester oils that have a better environmental footprint compared to standard mineral oils.

Gas insulation is another popular choice for power transformers due to its high dielectric strength and low maintenance. Gas-insulated transformers (GITs) use sulfur hexafluoride (SF6) as the insulating medium. They are widely used in high-voltage applications due to their ability to withstand high voltages. Meanwhile, solid insulation is a newer and an eco-friendlier option for power transformers. Solid-insulated transformers (SITs) use solid materials, such as epoxy resin or polyurethane, as the insulating medium.
