An ABB oil transformer is similar to an ABB oil-filled transformer
No, dry-type transformers are not filled with oil. Instead, they use air or other gases for cooling and insulation. The design of dry-type transformers eliminates the need for liquid insulation, making them safer for environments where fire risk is a concern. Overheating is managed through air circulation or other cooling methods, not by using oil.
Silicone oil in power transformers is primarily used as an insulating fluid. It helps to cool the transformer and prevent electrical discharges. Its high thermal stability and low volatility make it ideal for ensuring the reliable operation of transformers, even under extreme conditions, while also extending the lifespan of the equipment.
