What is dry type transformer inside?
Inside a dry-type transformer, you will typically find the primary and secondary windings, insulated from each other and encapsulated in a resin or epoxy material. This insulation provides protection against moisture and contaminants, making the transformer suitable for indoor applications where environmental conditions may vary.

The core material of a dry-type transformer is often made of high-quality silicon steel laminations. These laminations are stacked to form the core, providing a low-loss path for the magnetic flux generated by alternating current passing through the windings. The use of silicon steel helps reduce eddy current losses and improves transformer efficiency.
What are dry type transformers used for?
The working principle of a dry-type transformer is based on electromagnetic induction. When alternating current flows through the primary winding, it generates a magnetic field in the core, which in turn induces a voltage in the secondary winding. This voltage is proportional to the turns ratio between the primary and secondary windings, allowing the transformer to step back or step down the voltage as needed.
Dry-type transformers are so called because they do not use liquid insulation like oil or other dielectric fluids. Instead, they rely on solid insulation materials such as resin or epoxy to encapsulate the windings and core. This design eliminates the risk of leaks and spills associated with liquid-filled transformers, making dry-type transformers safer and more environmentally friendly. Additionally, the absence of liquid insulation simplifies installation and maintenance, as there is no need for special containment measures or periodic liquid testing.
