Product Description

DAYA 1200kva 12kV Dry Type Transformer Details

These dry-type transformers are offered encapsulated, ventilated or non-ventilated, 600 Volt Class, isolation type, single and three phase, through 500 kVA. Indoor and outdoor models are available. Transformers are useful where the available voltage must be changed to accommodate the voltage required by the load.

General Purpose

These industry workhorses feature dry type construction  and are classified as isolation transformers.

Low Temperature Rise

Lower thermal stress on transformer insulation increases useful life.

K-Factor Designed to reduce the heating effects of harmonic currents created by solid state loads.

Copper Wound

General purpose transformers have standard aluminum coil windings. As an option, copper windings are available.

DAYA 1200kva 12kV Dry Type Transformer Processing characteristics

Siemens Energy is closely monitoring the development of transformer regulations worldwide e.g. European Eco Design Directive and US DOE rules. Siemens Energy adheres to the rules and regulations communicated e.g. in US and Europe and complies with all relevant requirements for every transformer product delivered. As a trustful and responsible partner Siemens Energy understands the importance of these regulations and will continue to monitor potential future requirements. We will continue to adapt and comply with all relevant regulatory changes.


We produce the GEAFOL in accordance with VDE 0532-76-11/IEC 60076-11/ DIN EN 60076-11 and the Ecodesign Directive from the European Commission. Other standards, such as GOST, SABS, or CSA/ANSI/ IEEE, can also be taken into account on request. GEAFOL dry-type transformers also can be designed to meet special national specifications, or customers’ wishes. The high quality standard of the GEAFOL transformers was confirmed from the result of several tests: For example, one and the same GEAFOL transformer has passed all defined routine, type, and special tests, as well as additional tests, with flying colors. The comprehensive safety certification enables the use in almost every environment and under extremely harsh conditions such as:

  • Ambient temperatures of ± 60 °C
  • Aggressive, salt-laden atmospheres
  • Great mechanical stress e.g. on ships, cranes or nacelles of wind power plants
