❓ Frequently Asked Questions

Q1: What are the primary cooling methods for your oil-immersed transformers?

A1: We offer ONAN (Oil-Natural Air-Natural), ONAF (Oil-Natural Air-Forced), and OFAF (Oil-Forced Air-Forced) methods depending on capacity and application requirements.

Q2: What is the recommended operating temperature?

A2: The top oil temperature should ideally stay below 85°C for maximum longevity, though it can handle up to 90°C. An alarm is typically triggered at 80°C.

Q3: Do these transformers meet international standards?

A3: Yes, our transformers are designed and manufactured according to the IEC60076 standard and our facility is ISO9001 certified.

Q4: What materials are used for the windings?

A4: We provide both high-quality Copper and Aluminum winding options based on the specific load demands and customer specifications.

Q5: What is the typical overload capacity?

A5: During emergencies, our transformers permit a 1.1 to 1.2 times rated current. It is vital to monitor load and temperature closely during such periods.

Q6: How is the core constructed to reduce energy loss?

A6: We use laminated high-permeability silicon steel sheets with a near-circular cross-section to minimize air gaps, noise, and harmonic distortion.
