Scope
Main technical content: This standard specifies the terms and definitions, basic requirements, technical requirements, test methods and inspection rules, marking, packaging, transportation, storage, and quality commitments for energy-saving and low-noise three-phase dry-type power transformers (hereinafter referred to as dry-type power transformers) that use electrical steel strips. This standard applies to non-excited voltage-regulating three-phase dry-type power transformers with a voltage rating of 6 kV and 10 kV, a rated frequency of 50 Hz, and a rated capacity of 30 kVA to 2,500 kVA, for indoor use. Dry-type power transformers with other rated capacities may refer to this standard for use.
