Claims

[Scope of utility model registration request]

In an oil-immersed transformer equipped with a panel-like rib type heat radiator, which is made up of a heat radiator with multiple heat radiating ribs attached to the side wall of the tank, a core is inserted and fixed into the heat sink, and the top and bottom of this core are fixed. An oil-immersed transformer characterized in that a gap is formed in the heat radiation rib to communicate with the inside of the heat radiation rib.
