Product Q&A

Q:Are oil-immersed transformers only suitable for outdoor use?

No. Oil-immersed transformers are installable outdoors, indoors, and in box substations. With excellent heat dissipation and overload performance, they are popular in power grid and industrial scenarios and can operate indoors with ventilation and fire protection.

Q:Is noise during operation of oil-immersed transformers a fault?

Steady, uniform humming is normal electromagnetic noise. Sharp abnormal sounds, intense vibration, and unstable noise suggest issues like core looseness, unbalanced load, or abnormal voltage, needing timely maintenance.

Q:Does transformer oil need regular replacement?

Frequent replacement isn't needed. Regular quality tests, impurity filtration, and dehumidification suffice. Replacement is needed if oil is severely aged, damp, carbonized, or fails insulation standards.

Q:What are the core advantages of oil-immersed transformers compared with dry-type transformers?

They have higher heat dissipation efficiency, larger heat capacity, stronger overload resistance, longer service life, and lower maintenance costs, ideal for high-power, long-term industrial and power grid use.

Q:Can oil-immersed transformers operate under full load for a long time?

Yes. Standard oil-immersed transformers support long-term continuous operation at rated load with short-time overload margin. They can operate stably with qualified oil quality and good heat dissipation.
