A 110kV Transmission Transformer is a medium-to-high voltage power transformer designed for regional electricity transmission and distribution networks. It serves as a critical link between high-voltage transmission grids (e.g., 220kV/500kV) and local distribution systems, stepping down voltage from 110kV to lower levels (typically 10kV/35kV) for industrial, commercial, and residential use. Widely deployed in substations, industrial parks, and urban/rural areas, it ensures stable power supply, reduces transmission losses over medium distances, and supports reliable grid operation.
