Transõli

Transõli is a type of insulating oil used in electrical transformers. Its primary function is to provide electrical insulation between live parts and the transformer casing, as well as to dissipate the heat generated by the transformer's operation. This cooling and insulating capability is crucial for the efficient and safe functioning of electrical power transmission and distribution systems.

Historically, mineral oil derived from petroleum has been the dominant type of transformer oil. However, in recent decades, there has been increasing interest and use of alternative dielectric fluids, including natural esters and synthetic esters. These alternatives are often promoted for their improved fire safety characteristics and biodegradability compared to traditional mineral oils.

The selection of transõli depends on various factors, including the transformer's design, operating environment, and specific performance requirements. Environmental regulations and sustainability concerns are also playing an increasingly significant role in the choice of dielectric fluids. Proper maintenance and monitoring of transõli levels and condition are essential to ensure the longevity and reliability of transformers. Testing of the oil's dielectric strength, moisture content, and other properties is a standard part of transformer maintenance.
