Nr. 238797aussenliegenden und/oder mit mehreren innenliegenden Abschlussbandagen versehen wird, wobei die Spannungssteuerungsbeläge auf den un-, an-oder ausgehärteten Teilisolationswickel aufgebracht werden. 
 EMI2.1 
 



   Der nach diesem Verfahren hergestellte spannungsgesteuerte Hochspannungsleiter ist einfach zu erzeugen und ist wegen seiner glasfasergefüllten Epoxyharzisolation mechanisch und elektrisch fester, feuchtigkeitsunempfindlicher, kriechstromfester und glimmbeständiger als die bisher bekannten   Ausfüh-   rungen. 



   Die thermischen Eigenschaften der neuen spannungsgesteuerten Isolation sind den Bauarten mit thermoplastischen Isolierstoffen oder   reissempfindlichen   epoxyharzgetränkten Papierbändem überlegen, was insbesondere im Kurzschlussfall von Vorteil ist. 



   Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt :
In Fig. 1 wird auf dem Leiter 1 das mit heisshärtendem Kunstharz imprägnierte Band 2 (vorzugsweise epoxyharzgetränktes Glasseidenband) unter jeweiliger Zwischenlage eines Spannungssteuerungsbelages 3 aufgebracht und abschliessend der gesamte Verbundwickel gemäss dem Stammpatent mit einer Abschlussbandage 4 versehen. 5 ist die Metallisierung der Isolationsoberfläche. 



   Wie in Fig. 2 dargestellt wird auf dem Leiter 1 das mit heisshärtendem Kunstharz imprägnierte 
 EMI2.2 
 oder Lackieren aufgebracht, wodurch auf die nun harte Unterlage die weiteren Kunstharzschichten leicht aufzuwickeln sind, was insbesondere bei höheren Spannungen vorteilhaft ist. Durch mehrmaliges Aufbringen der Teilisolation mit Spannungssteuerungsbelägen entsteht dann die massive Sammelschienenisolation.

No. 238797 is provided with external and / or with several internal closing bandages, the tension control coverings being applied to the uncured, partially cured or cured partial insulation coil.
 EMI2.1
 



   The voltage-controlled high-voltage conductor produced according to this process is easy to produce and, due to its glass fiber-filled epoxy resin insulation, is mechanically and electrically stronger, less sensitive to moisture, more creep current and more corrosive than the previously known designs.



   The thermal properties of the new voltage-controlled insulation are superior to the types with thermoplastic insulating materials or tear-sensitive epoxy resin-impregnated paper tapes, which is particularly advantageous in the event of a short circuit.



   Embodiments of the invention are shown in the drawings:
In Fig. 1, the tape 2 impregnated with hot-curing synthetic resin (preferably epoxy resin-impregnated glass silk tape) is applied to the conductor 1 with a respective intermediate layer of a tension control coating 3 and finally the entire composite winding is provided with a closing bandage 4 according to the parent patent. 5 is the metallization of the insulation surface.



   As shown in Fig. 2, the impregnated with thermosetting synthetic resin is on the conductor 1
 EMI2.2
 or lacquering, whereby the further synthetic resin layers can easily be wound onto the now hard base, which is particularly advantageous at higher voltages. The massive busbar insulation is then created by applying the partial insulation several times with voltage control coatings.
