Abstract: A method for filling an electrical device with a multi-component insulating filler, including the steps of: mixing at least two components of insulating filler each with compressible microspheres; measuring at regular intervals a viscosity of each of the at least two components of insulating filler mixed with the microspheres until each of the at least two components of insulating filler have a substantially uniform viscosity; mixing the at least two components of insulating filler together in order to obtain a multi-component insulating filler; extracting air present in a free volume V of the electrical device using a vacuum pump; filling the free volume V of the electrical device with the multi-component insulating filler until the free volume V of the electrical device is completely filled; and injecting an additional amount of the multi-component insulating filler in order to develop overpressure.

Abstract: The present invention relates to a pole head for supporting conductors on poles for medium- and high-voltage overhead power lines, having at least one tubular portion which has a structural function, is made of electrically insulating composite material, and is fixed to a supporting structure. Coupling flanges for supporting the electrical conductors are connected to the at least one tubular portion and are mutually spaced along the axis of the tubular portion.
