Abstract: The conductor, including the points being kept free insulation, is initially surrounded by a liquid, electrically non-conducting bonding agent which forms the insulation after solidifying. The conductor can be a transposed conductor in which the individual conductors thereof are electrically isolated relative to each other and are interconnected by the bonding agent. Using a liquid stripping agent based on a polyvinyl alcohol or a long-chain hydrocarbon mixture and a polysaccharide filler on the point of the conductor being kept free of the insulation locally prevents the bonding agent from bonding to the conductor or the individual conductors of the transposed conductor from being interconnected by means of the unsolidified mixture. Once the entire bonding agent is hard and thus the bonding agent/stripping agent mixture has solidified, the bonding agent/stripping agent mixture can easily be removed in a mechanical manner from the treated points of the conductor.

Abstract: A method removes corrosive sulfur compounds from transformer oil. By adding a mixture of rare earths containing aluminum oxide and aluminum silicate to the transformer oil, and enriching the same with an aqueous solution of soluble metal salts, the corrosive sulfur compounds in the transformer oil are neutralized with defined heating and cooling phases. Advantageously, no additional chemical components, such as passivators, are added to the transformer oil. When using a tank for receiving the mixture of the rare earths containing aluminum oxide and aluminum silicate, the reaction can run in the tank. Any aging products that may be present, and the bonded corrosive sulfur compounds are effectively retained within the tank by a filter system, and can be disposed of with the tank.

Abstract: A barrier system for a line leadthrough in an electric installation has mutually adjacent wall elements forming barriers that extend in an axial longitudinal direction and are spaced apart from each other, forming channels. The wall elements lie partially on a support, at least at their lower ends. The wall elements are joined by a plug element to the leadthrough. Slots having a width which corresponds to the wall thickness of the wall elements are arranged in the plug element. The wall elements can be inserted into the slots, thus permitting a barrier system to be quickly and easily assembled and disassembled.

Abstract: An electrical shielding arrangement of a high-voltage line has at least two coupling elements. The coupling elements each have a tubular control electrode about a line leadthrough and are surrounded by a barrier. Owing to the fact that the reduction in the diameters of the control electrode and the barrier is matched in relation to one another, a barrier decoupled in this way can be used for mechanically tensioning the coupling systems which have been pushed one inside the other.

Abstract: A connecting element between a first electric shielding assembly that surrounds a cable feedthrough and includes at least one tubular insulating barrier that surrounds the cable feedthrough and at least one second electric shielding assembly that surrounds the cable feedthrough and includes at least one tubular insulating barrier that surrounds the cable feedthrough. A continuous barrier system around the cable feedthrough is provided by a connecting element with at least two interconnecting insulating barriers, which can be inserted into the shielding assemblies, even if the shielding assembly is configured from sub-segments. The disclosure also relates to an electric shield for a cable feedthrough and to a method for producing an electric shield for a cable feedthrough.

Abstract: A method for producing an electric conductor with an insulation and at least one point that is to be kept free of the insulation. The conductor, including the points that are to be kept free insulation, is initially surrounded by a liquid, electrically non-conducting bonding agent, above all an epoxy resin, which forms the insulation after solidifying. The conductor can also be composed of several individual wires, particularly a transposed conductor, said individual conductors being electrically isolated relative to each other and being interconnected, especially glued together, by means of the bonding agent. Using a liquid stripping agent that is based on a polyvinyl alcohol or a long-chain hydrocarbon mixture and a polysaccharide filler on the point of the conductor which is to be kept free of the insulation locally prevents the bonding agent from bonding to the conductor or the individual conductors of the transposed conductor from being interconnected by means of the unsolidified mixture.
