A distribution transformer is a key electrical device that steps down high-voltage electricity to a lower voltage suitable for commercial, residential, or industrial use. It consists of vital components like core (usually made of silicon steel) for magnetic flux, windings (copper or aluminum) for current conduction, and insulating oil to maintain temperature and prevent electrical faults. Modern fabrication techniques employ advanced design technologies like computer-aided modeling for efficiency and precision. Types include dry and oil-immersed transformers. Widely used in power utilities, construction, manufacturing, and telecom, they offer energy efficiency, reducing transmission losses and supporting stable power supply across industries.
