Dowei Electric Substation Transformer SST

Product catalog summary

General Description:

The substation transformers comply with international standards such as IEC 60076, ANSI/IEEE Std C57.12, and NEMA.
They are certified by ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA.
Transformers use mineral oil or vegetable oil (FR3) and are free of PCBs.
They are designed to withstand seismic activities as per ETGI-1.020, IEEE Std 693, and NCh2369.
Structural design follows ASTM A325, ANSI/AISC 360, and AWS D1.1 standards.
High altitude correction is available up to 5000m according to IEC 60076 & IEEE C57.12.

Product Scope:

Available in sizes ranging from 225 to 15,000 KVA.
Primary voltages range from 2400 to 69,000 V, and secondary voltages from 220Y/127 to 34,500 V.
Cooling methods include ONAN, ONAN/ONAF, KNAN, KNAN/KNAF.
Compatible with various fluids: Mineral oil, FR3, Silicone, Beta Fluid, Alpha Fluid.
Standard impedance is in accordance with ANSI C57.12.36.
Complies with Department of Energy (DOE) standards.
Finished with ANSI 61 color.

Typical Specification:

Performance data is provided for high voltage (15 kV Class) and low voltage (600 V Class) transformers.
Efficiency varies with load, reaching up to 99.53% at 50% load for certain models.
Full load losses and efficiencies are measured at a reference temperature of 85 °C, while efficiencies for transformers rated 75–2,500 kVA at 50% load are measured at 55 °C.

Performance Data Summary:

Transformers exhibit varying no-load and full-load losses, with total losses increasing with kVA rating.
Efficiency generally improves with reduced load, peaking at 50% load for most models.
