what is inside a power pole transformer?

A power pole transformer, commonly used in electrical distribution, contains several key components. Inside, you’ll find copper or aluminum windings that facilitate voltage transformation, a core made of laminated silicon steel to enhance magnetic efficiency, and insulation materials to prevent electrical shorts. Additionally, it contains oil or resin for cooling and insulation, along with protective devices like fuses or circuit breakers. These components work together to step down high voltage from power lines to a safer, usable level for residential or commercial use.
