FAQ's of Furnace Transformers:

Q: How do I select the suitable impedance for my furnace transformer?

A: Choosing an impedance of 5% or 7.5% depends on your application's short-circuit tolerance and voltage regulation needs. If greater customization is required, we can provide tailored impedance values to optimize performance for your specific furnace load.

Q: What insulation class should I opt for and why?

A: Insulation classes A, F, and H denote different temperature withstand capacities. Class A is suited for standard conditions, while F and H offer enhanced performance in higher temperature environments. Selecting the right class ensures the transformer's longevity and efficiency.

Q: When is it necessary to use a tap changer, and which type is best?

A: Tap changers allow voltage adjustment according to the load or supply fluctuations. For applications needing real-time voltage regulation, an On-load Tap Changer (OLTC) is ideal, while Off-load Tap Changers are sufficient if changes are infrequent and can be performed during shutdowns.

Q: Where are your furnace transformers typically installed?

A: These transformers are designed for industrial settings, particularly where electric furnaces are used-such as steel plants, foundries, and other heavy manufacturing facilities. Their robust design makes them suitable for both indoor and outdoor installations.

Q: What is the typical process for customization and OEM service?

A: Upon receiving client specifications, we engage in detailed consultations to tailor transformer parameters like voltage, impedance, bushing type, mounting, and more. Our team ensures compliance with IS 2026 and IEC 60076 standards while accommodating special requests.

Q: How do these transformers ensure operational safety and reliability?

A: With integrated protection devices like Buchholz Relays, WTI, OTI, PRV, and oil level gauges, combined with high-quality materials and construction, our transformers meet stringent safety standards and offer reliable performance under demanding industrial conditions.

Q: What benefits do I gain from choosing this transformer for my furnace application?

A: You benefit from high efficiency (up to 98%), excellent regulation, advanced protection, and adaptability to diverse voltages and currents. Customization options, robust construction, and compliance with global standards ensure seamless integration and dependable operation in your facility.
