Abstract

An improvement in the object of the main patent number 251,535 which relates to a process for obtaining a product for the impregnation of high-voltage cables, consisting essentially of employing in the constitution of the product and one or several alkylbenzenes with aliphatic chain ( both linear and branched) of 9 to 11 carbon atoms, and obtain a viscosity comprised between 2 and 10 centistokes at 20º centigrade and a point of flammability in open glass (Marcusson) greater than 100º centigrade.
