single-phase dry-type transformer operates using the principle of electromagnetic induction to step up or step down voltage without using any liquid insulation. Instead, it relies on air and solid insulation materials, such as epoxy resin, to provide electrical insulation and cooling.
Single-phase dry-type transformers offer a reliable and safe solution for voltage transformation in diverse electrical applications. Their design features, advantages, and suitability for various environments make them a preferred choice in modern electrical installations.
