isolatsioonõli
Isolatsioonõli, also known as insulating oil or dielectric oil, is a specially refined mineral oil used in electrical equipment such as transformers, circuit breakers, and capacitors. Its primary function is to provide electrical insulation and dissipate heat. The high dielectric strength of the oil prevents electrical arcing between live components and the grounded casing of the equipment. This insulation is crucial for the safe and efficient operation of high-voltage electrical systems.
Beyond its insulating properties, isolatsioonõli also serves as a coolant. In transformers, for instance, it circulates
The quality of isolatsioonõli is paramount. It must be free from moisture, dissolved gases, and conductive impurities,
