A cooling arrangement for a dry-type transformer. The arrangement includes blowing equipment configured to blow a gas flow, and an opening positionable in a clamping structure of the transformer. The opening is configured to allow the gas flow to pass from the blowing equipment towards a winding of the transformer, so that the winding is properly cooled. The opening comprises an electric protecting means for dielectric protection of the clamping structure. A transformer including such cooling arrangement is also disclosed.
