What are the specifications for an oil-immersed transformer?

When discussing specifications for an oil-immersed transformer, it’s essential to consider several key aspects such as insulation system, cooling method, operating temperature range, dielectric strength, and environmental compliance. The insulation system typically involves High-Voltage Insulating Oil which must meet specific standards, including IEC 60296 for mineral oil quality. Cooling is usually facilitated through natural or forced convection, and the transformers are designed to operate within a temperature range of -30°C to +90°C, depending on the application. Dielectric strength is crucial, with transformers usually requiring oils with a dielectric breakdown voltage of at least 30 kV for optimal performance. Additionally, manufacturers must ensure that the transformer complies with environmental regulations regarding oil leakage and waste disposal. Choosing reputable oil immersed transformer manufacturers ensures high-quality construction and compliance with these critical specifications, optimizing longevity and performance.
