FIELD: electricity.
SUBSTANCE: invention is related to transformer. Transformer comprises magnetic conductor with at least one primary and secondary windings and housing. Windings are made from aluminum wire with ceramic insulation. Body is made from metal as sealed. In housing containing gas-dielectric, magnetic conductor with windings is placed tightly to metal housing. At that, pressure of gas-dielectric in housing is 5⋅10-2 Pa or less.
EFFECT: higher voltage value corresponding to the onset of breakdown of windings, while maintaining safety of operation of transformer and improved heat removal of windings.
