Product Q&A
Q:What's the difference between copper and aluminum windings?
A:
Copper has lower resistance, higher efficiency, better heat resistance and durability, but higher cost; aluminum is cheaper but requires larger cross-section for same current.
Q:Can a 50Hz transformer be used with 60Hz power, or vice versa?
A:
Generally not recommended. Deviation in frequency will change core loss, impedance and cooling performance, possibly causing overheating or damage.
Q:Why does a transformer hum? How to reduce it?
A:
Mainly from magnetostriction of the core under AC. Solutions: Use low-noise core materials, improve clamping, ensure no DC in windings, and proper installation.
Q:What are the main losses in a transformer?
A:
Iron loss (hysteresis + eddy current, constant with load) and copper loss (winding resistance loss, load-dependent).
Q:How to handle transformer overheating?
A:
First cut off load and power; check cooling system, ventilation, loose connections, overload or internal faults, then troubleshoot and repair.
