Product Q&A
Q:Are oil-immersed transformers only suitable for outdoor use?
A:
No. Oil-immersed transformers are versatile for outdoor, indoor, and box substations. They excel in heat dissipation and overload performance, widely used in power grids and industries, suitable indoors with proper ventilation and fire safety.
Q:Is noise during operation of oil-immersed transformers a fault?
A:
Steady humming is typical electromagnetic noise. Sharp, erratic sounds and vibrations suggest issues like core looseness, load imbalance or voltage anomalies, needing timely maintenance.
Q:Does transformer oil need regular replacement?
A:
Frequent replacement isn't needed. Regular quality testing, impurity filtration, and dehumidification suffice. Replacement is necessary only when oil is severely aged, damp, carbonized, or fails insulation.
Q:What are the core advantages of oil-immersed transformers compared with dry-type transformers?
A:
They offer superior heat dissipation, greater heat capacity, stronger overload resistance, longer lifespan, and lower maintenance, ideal for high-power, long-term use in industrial and power grid settings.
Q:Can oil-immersed transformers operate under full load for a long time?
A:
Yes. Standard oil-immersed transformers support continuous rated load operation with short-term overload margin. They operate stably with good oil quality and effective heat dissipation and ventilation.
