What are the technical considerations for transformers oil cooled?

When considering oil-cooled transformers, key technical factors include the type and quality of insulating oil, thermal management, and cooling efficiency. The oil must have high dielectric strength and low viscosity to ensure effective heat dissipation. Additionally, the design should facilitate proper circulation of oil to maintain uniform temperature distribution. Regular monitoring for moisture and contaminants is essential to prevent degradation of insulation properties and ensure reliable operation.
