Beschreibung
Zusammenfassung:	A transformer oil basestock is disclosed that includes at least 99 wt% of naphthenes and paraffins, based on the total weight of the transformer oil basestock, wherein the weight ratio of naphthenes to paraffins is at least 1, as measured by GC-MS, and wherein the paraffins consist essentially of isoparaffins, as determined by GC-FID. In addition, a transformer oil composition is disclosed that includes the transformer oil basestock, an anti-gassing agent and an antioxidant. L'invention concerne une huile de base de transformateur qui comprend au moins 99 % en poids de naphtènes et de paraffines, sur la base du poids total d'huile de base de transformateur, le rapport pondéral des naphtènes sur les paraffines étant d'au moins 1, tel que mesuré par GC-MS, et les paraffines étant constituées essentiellement d'isoparaffines, telles que déterminées par GC-FID. De plus, l'invention concerne une composition d'huile de transformateur qui comprend l'huile de base de transformateur, un agent anti-gazage et un antioxydant.
