FAQ

Q: What is ester oil in transformers?
A: Ester oil in transformers is a biodegradable insulating and cooling fluid, offering higher fire resistance and environmental safety than traditional mineral oil.

Q: What is an oil-filled transformer?
A: An oil-filled transformer is an electrical device that uses insulating oil (like mineral or ester oil) as both a coolant and dielectric medium. The oil helps dissipate heat generated during operation and prevents electrical arcing between components, ensuring safe and efficient power transfer between voltage levels. It is widely used in power grids, industries, and commercial settings for its reliability and thermal performance.

Q: What kind of oil is used in transformers?
A: Transformer oils mainly include three types:
Mineral Oil: Derived from petroleum, it offers good insulation and heat dissipation but is flammable and non-biodegradable.
Synthetic Oil (e.g., Silicone Oil): Chemically produced, it is heat-resistant, non-flammable, and used in high-temperature or fire-sensitive environments.
Ester Oil (Natural/Synthetic): Extracted from plants or chemically synthesized, it has low flammability, biodegradability, and is eco-friendly, suitable for indoor use or ecologically sensitive areas.
