Abstract

L'invention concerne un fluide d'isolation électrique extrêmement performant à basse température, spécialement destiné aux transformateurs. Ce fluide contient des esters contenant de 17 à 20 atomes de carbone, formés par réaction d'un acide carboxylique monobasique saturé avec un alcool monohydrique. Les esters adéquats contiennent les substances suivantes: n-décyl 2-éthyl hexanoate, 2-éthyl hexyl 3,5,5-triméthyl hexanoate, isodécyl 2-éthyl hexanoate, isodécyl isooctanoate, isodécyl 3,5,5-triméthyl hexanoate et n-octyl/n-décyl 2-éthyl hexanoate. En plus des esters, le fluide peut contenir comme additif, un stabilisateur contre l'oxydation. Parmi les additifs adéquats, on trouve un antioxydant, tel qu'un phénol empêché, et un agent passivant de métaux, tel qu'un benzotriazole ou un dérivé de ce dernier.
