Transformer cooling system and transformer installation

A transformer installation, comprising:

• first dry transformer and a second dry transformer, each comprising:
• a core comprising a leg,
• a winding body arranged around the leg, and
• a cooling channel in a direction of a longitudinal axis of the winding body, the cooling channel being disposed between an inner part of the winding body and an outer part of the winding body, and the cooling channel having a first opening provided at a first end of the cooling channel and a second opening provided at a second end of the cooling channel,
• a first flow generating device for providing a cooling flow in the cooling channel of the first dry transformer, the first flow generating device being connected to the cooling apparatus,
• a second flow generating device for providing a cooling flow in the cooling channel of the second dry transformer, the second flow generating device being connected to the cooling apparatus,
• a first housing containing the first dry transformer and the first flow generating device,
• a second housing containing the second dry transformer and the second flow generating device, and
• a cooling apparatus in fluid communication with the first housing and with the second housing, the cooling apparatus being adapted to dissipate heat from the first housing and from the second housing.
