Abstract

L'invention concerne des compositions de triglycérides riches en acide oléique, qui contiennent des composants acides gras constitués d'au moins 75 % d'acide oléique, moins de 10 % d'un composant acide gras bi-insaturé, moins de 3 % d'un composant acide gras tri-insaturé, et moins de 8 % d'un composant acide gras saturé; et ayant comme propriétés une rigidité diélectrique égale à au moins 35 kV/100 mu m d'espace inter-électrodes, un facteur de dissipation inférieur à 0,05 % à 25 DEG C, une acidité inférieure à 0,03 mg KOH/g, une conductivité électrique inférieure à 1 ps/m à 25 DEG C, un point éclair d'au moins 250 DEG C et un point d'écoulement d'au moins -15 DEG C. L'invention concerne également un fluide isolant contenant ladite composition de triglycérides. Elle concerne aussi des appareils électriques contenant ledit fluide isolant et l'utilisation de ce dernier pour isoler les appareils électriques. Elle concerne enfin un procédé permettant de préparer la composition de triglycérides riche en acide oléique.
