FIELD: chemistry.
SUBSTANCE: claimed invention relates to composition, suitable for application in electric equipment, containing dielectric liquid. Claimed dielectric composition includes oil component, with oil component containing crambe oil and/or rapeseed oil with high content of erucic acid, as well as etherified crambe oil and/or etherified rapeseed oil with high content of erucic acid, with oil component having content of erucic acid at least 45 wt %. Introduction of esters, claimed in accordance with claimed invention, makes it possible to reduce oil component viscosity.
EFFECT: increase of thermal stability and specific resistance of oil component, as well as reduction of its impact on the environment.
