Abstract

An electrotechnical fluid composition, comprising more than 90 wt-% paraffins in the C17-C18 range, based on the total weight of the composition, is described. The ratio of the amount of C18 i-paraffins to the amount of C18 n-paraffins is more than 40, based on the weight of the C18 i-paraffins and the weight of the C18 n-paraffins in the composition.

First claim
