Oil-immersed transformers are widely used in power transmission, utility substations, industrial plants, renewable energy projects, and large-scale distribution networks. Thanks to their excellent cooling performance, high efficiency, and ability to handle large capacities, they remain one of the most reliable transformer types in modern power systems.<\/p>\n\n\n\n
However, many buyers focus only on transformer capacity and price while overlooking critical factors such as insulation design, cooling methods, loss performance, maintenance requirements, and installation environment. These details can significantly affect operating costs and equipment lifespan.<\/p>\n\n\n\n
This guide explains how oil-immersed transformers work, where they are used, and what buyers should consider before selecting one.<\/p>\n\n\n\n
