Product Description
12.5MVA Furnace Transformer System
Dedicated Power Supply for Medium-Low Carbon Ferromanganese Refining Furnaces
Product Overview
The WN-FT-12.5MVA-35/0.38 is a purpose-built furnace transformer designed to deliver reliable, high-current power to electric ladle refining furnaces producing medium-low carbon ferromanganese. With an input voltage of 35kV stepped down to 380V at 12.5MVA, this oil-immersed transformer features on-load tap changing, advanced OFAF cooling, and Class H insulation for continuous heavy-duty operation in demanding metallurgical environments.
Key Features
⚡ 12.5MVA Rated Capacity
Engineered for high-current output to support large ferromanganese ladle refining furnaces with stable arc characteristics and minimal voltage fluctuation.
🔄 On-Load Tap Changer (OLTC)
13-position on-load tap changer enables dynamic voltage adjustment without interrupting furnace operation, ensuring optimal power delivery throughout the refining cycle.
💧 OFAF Cooling Technology
Forced oil-air cooling system with high-efficiency radiators and fans maintains safe operating temperatures even under continuous full-load conditions.
🛡️ Class H Insulation
Premium electrolytic copper windings with Class H (180°C) insulation system provide extended service life and exceptional thermal endurance in harsh furnace environments.
📊 Digital Monitoring System
Integrated PT100 temperature sensors with digital controller for real-time oil temperature, winding temperature, and cooling system status monitoring.
🔧 Customizable Configuration
Adjustable impedance (6-8%), flexible vector group (Dyn11/YNd11), and optional accessories to match specific furnace specifications and site requirements.
