10kv Distribution Transformer with Copper Winding and 2500kVA Rating

No. Oil-immersed transformers can be installed outdoors, indoors and in box substations. With excellent heat dissipation and overload performance, they are widely used in power grid and industrial scenarios, and can work indoors with proper ventilation and fire protection measures.

Steady and uniform humming sound is normal electromagnetic noise. Sharp abnormal sound, intense vibration and unstable noise indicate abnormal operation caused by core looseness, unbalanced load or abnormal voltage, which requires timely maintenance.

Frequent replacement is not required. It only needs regular quality testing, impurity filtration and dehumidification. Oil replacement is only needed when the oil is severely aged, damp, carbonized or fails insulation standards.

They feature higher heat dissipation efficiency, larger heat capacity, stronger overload resistance, longer service life and lower overall maintenance costs, making them more suitable for high-power and long-term continuous operation in industrial and power grid conditions.

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