This European Standard covers dry type transformers from 100 kVA to 3 150 kVA intended for operation in three phases distribution networks, for indoor continuous service, 50 Hz, natural cooling, with two windings: - a primary (high voltage) winding with a highest voltage for equipment of 3,6 kV to 36 kV; - a secondary (low voltage) winding with a highest voltage for equipment not exceeding 1,1 kV. For outdoor application, special design or enclosure (enclosure with adapted IP and IK degrees protections) should be requested.
