摘要

A refinement in the method for splicing by soldering a substantially free area of insulating oil between a unipolar cable of fluid oil with conductor with internal channel for the flow of oil and another conductive element of an electrical device, in which a tube has has been inserted in the internal channel of the oil in the welding zone, in order to prevent the oil from leaving in said area and in which the cut ends of the insulation have been bound with oil-impermeable tapes and have been applied to the bare conductors. Suction of the oil leaving the interstices between the various elements of the conductors, characterized in that it consists of inserting the tube in said channel by a predetermined length, controlled by a spacing means applied in said tube; - in approaching the head of the driver the other element to be joined until the piece of tubing left free by the spacing means is completely occupied, this improvement being further characterized by the fact that around the bare conductor there are limited extension means capable of containing displacements radial portions of the bare conductor, in correspondence of seating seats for fittings applied to the tube and externally invoked in relation to the position of the spacing means; - carrying out the welding after having removed the spacing means and in the space previously occupied by said means, removing the means of limited extension after welding.
