Difference between dry transformers and oil transformers
Transformers are essential in electrical systems to modify alternating current voltage, and among them, dry transformers and oil transformers stand out as two predominant variants. While dry transformers use solid insulating materials, such as resins, and are cooled by surrounding air, oil transformers use oil as both an insulating and cooling medium. This difference in construction leads to variations in their operation: oil transformers may be more efficient in dissipating heat but carry the risk of spills and leaks. In contrast, dry transformers, not relying on oil, are less prone to such risks and are ideal for indoor spaces and areas with environmental concerns. Both have specific applications based on their individual advantages and limitations. We specialize in maintenance for dry electrical transformers, so do not hesitate to seek our advice if needed.
