what is inside a high voltage transformer?

A high voltage transformer consists of several key components. The core, typically made of laminated silicon steel, provides a magnetic pathway for the magnetic flux. The primary and secondary windings, made of copper or aluminum wire, are insulated and wrapped around the core. Insulation materials, such as oil or solid dielectric, surround the windings to prevent electrical breakdown. Additionally, there are cooling systems to dissipate heat generated during operation, ensuring efficient performance.
