Dowei Electric Furnace Transformer HSSPZ

Product catalog summary

General Description:
The document provides specifications for Electric Arc Furnace (EAF) Transformers manufactured by Ningbo Dowei Electric Co., Ltd. These 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. The transformers use mineral or vegetable oil (FR3) and are free of PCB. Cooling types include ONAN, ONAF, OFAF, and OFWF. They are designed for use in gas factories, steel plants, and calcium carbide industries, with seismic and structural designs adhering to standards like IEEE Std 693 and ASTM A325.

Typical Specifications:
The document lists detailed specifications for various transformer models, ranging from 1500 kVA to 200,000 kVA. Key parameters include:

Rated Capacity: 35~66kV
Vector Group: Yd11, D-Y,d0-11, Dd0
Primary Voltage: 35 kV
Secondary Voltage: Varies per model
Regulation Voltage Step: Off-load or On-load
Impedance: Varies from 5.5% to 10%
No-load and On-load Losses: Specified in kW for each model
Weight: Detailed for active part, oil, transportation, and total weight

These specifications are crucial for determining the suitability of each transformer model for specific industrial applications.
