Altitude: Applicable to areas with an altitude of no more than 1000m.
500KVA three-phase ONAN oil-immersed transformer structural features
Cooling method: The cooling methods of oil-immersed transformers include natural cooling (ONAN), forced air cooling (AF) and forced water cooling (AW). Natural cooling is to dissipate heat through convection and conduction of oil, which is suitable for small-capacity transformers.
Insulation material: The transformer body is installed in a welded steel tank filled with insulating oil to ensure that the equipment can maintain a low temperature during operation. The thickness of the winding insulation layer will increase with the increase of voltage, providing better insulation protection.

500KVA three-phase ONAN oil-immersed transformer application scenarios and maintenance recommendations
Application scenarios: Widely used in power distribution or substations, suitable for various occasions requiring high-efficiency performance, such as power transmission and distribution networks, renewable energy generation and small industries.
Maintenance:
Regularly check the quality of the oil: The quality of the oil is crucial to the life and safety of the transformer and requires regular inspection and maintenance.
Regularly check the transformer system: Ensure its normal and safe operation to prevent failures caused by improper maintenance.
Waste disposal: Waste generated by oil is easy to pollute the environment, so waste disposal is also very important
