Dowei Electric Pad-mounted Transformer ZGS

Product catalog summary

General Description:
The pad-mounted transformers adhere to 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. The transformers use mineral or vegetable oil (FR3) and are free of PCBs. They are designed for seismic conditions and high altitudes up to 5000 meters, following standards like IEEE Std 693 and ASTM A325.

Product Scope:
The transformers range from 45 to 5,000 KVA in size, with primary voltages between 2400 and 34,500 V and secondary voltages from 208Y/120 to 4,160 V. They include features like expulsion type Bay-O-Net fuses, three on/off loadbreak switches, and both radial and loop feed arrangements. The transformers are available in dead and live front types and are painted olive-green.

Available Ratings:
The transformers are available in various sizes from 45 kVA to 5000 kVA, with frequency options of 60 Hz or 50 Hz. Cooling classes include ONAN or KNAN, and temperature rise options are 55°C, 65°C, or 55/65°C. Voltage configurations are available in delta or Y configurations, with specific voltage ratings for different kV classes.

Typical Specification:
Performance data for high voltage (15 kV class) and low voltage (600 V class) transformers are provided. Efficiency varies with load, reaching up to 99.53% at 50% load for certain models. Losses and efficiencies are measured at reference temperatures of 85°C and 55°C, in accordance with IEEE and DOE standards.
