Closed Core Power Transformer Market Segmentation:

Cooling Segment Analysis

The oil-immersed segment is anticipated to capture 58.9% of the global closed core power transformer market share by 2035 owing to its superior thermal conductivity. The oil-immersed or oil-filled power transformers are set to exhibit widespread demand in the coming years due to their effectiveness in cooling the transformer temperature. Also, oil-immersed closed core power transformers can handle huge power loads compared to their counterparts, which makes them suitable for high-demand applications. Small-scale industries and renewable energy projects highly utilize ground oil-type transformers due to their energy efficiency and durability features.

Mounting Segment Analysis

The pad-mounted closed core power transformers segment in the closed core power transformer market is estimated to account for 40.7% of the revenue share through 2035 due to their high installation in underground power distribution projects. They are locked in a steel cabinet and mounted on a concrete platform to effectively and safely maintain voltage fluctuations and energy transmission. The pad-mounted power transformers are available in various phase designs such as single or three-phase, making them versatile to use in several applications. Furthermore, the integration of advanced materials and designs is improving the insulation and cooling techniques of pad-mounted transformers, leading to their high use in utility companies.
