		Dry-type transformers with epoxy resin insulation GEAFOL (manufactured « «Siemens Zrt.»);



низковольтные комплектные распределительные устройства, низковольтные комплектные распределительные устройства, низковольтные комплектные распределительные устройства.

Three phase step-down dry-type GEAFOL transformers with epoxy resin insulation within the rating power range from 100 up to the 3150 kVA and voltage up to 35 kV are used in various branches if industry.

Siemens GEAFOL transformers are most suitable for installation that require a high degree of safety, such as: hospitals, shopping centres, coltural centres, undeground railways etc.

Transformers are designed to minimize environmental contamination and fire hazard. These transformers are not flammable, they are self-extinguishing and in evett of a reakdown there is no risk of of inflammation or contaminating substances.

Vector group Dyn 11 or Yy0.
Off-load voltage requlation ±2×2,5 % by connecting links.
Distribution transformers in accordance with IEC 60076-11, 50 Hz, low voltage 400V.
