Advantages

1. Understanding Furnace Transformer Applications

Furnace transformers are designed for metal melting, arc furnaces, and industrial heating, ensuring stable and efficient operation. They also handle frequent load fluctuations and high thermal stress.

2. Selecting the Right Furnace Transformer

When selecting the right furnace transformer, consider power capacity, voltage ratings, and cooling systems to match the furnace's needs.

  • Power Capacity: Choose based on furnace kVA/MVA requirements.
  • Voltage Ratings: Ensure compatibility with input and output voltage levels.
  • Cooling System:
    • Oil-Cooled: Ideal for high-power applications.
    • Forced-Air / Water-Cooled: Suitable for compact setups.

Furnace transformers ensure stable power supply and efficient voltage control for metal melting and refining. Choosing the right transformer based on power capacity, cooling system, and protection features enhances operational reliability and longevity.
