Sie sind auf einem Muffengestell 10 verschiebbar mit Schrauben durch die Löcher 9 befestigt. Zur Montage der Muffe in der Kabelstrecke werden die Kopfieile 8 über die Kabel 15 geschoben, so daß die Spleißriiume 14 für die Ausführung der Spleißarbeiten zugänglich sind. Nach der Durchführung der Splcißarbeiten, wobei die Kabeladern mit den Spulenanschlüssen 16 oder durch das abgedichtete Rohr 4 hindurch direkt miteinander verbunden weiden, werden die Kopfteile 8 mit ihren Flanschen 11 an den Flanschen 2 des zylindrischen Mittelteils 1 befestigi. Zur Verbesserung der Druckdichligkeit können Dichtungen /wischen die Flanschen 2 und 11 eingegcfügi werden. Kabelmäntel aus Metall werden dann am Lötstuizen 12 gelötet bzw. verschmiert. Eine Wärmebclaslung der Spulen wird auch bei unsachgemäßer Ausführung einer solchen Löt- b/w. Schmierverbindung wegen der großen Entfernung der Lötstelle vom Spulenraum minimal bleiben.

They are attached to a socket frame 10 so that they can be moved with screws through the holes 9. To assemble the sleeve in the cable section, the headers 8 are pushed over the cable 15 so that the splice strips 14 are accessible for performing the splicing work. After the splitting work has been carried out, with the cable cores being connected directly to one another with the coil connections 16 or through the sealed tube 4, the head parts 8 with their flanges 11 are fastened to the flanges 2 of the cylindrical central part 1. To improve the pressure tightness seals / between the flanges 2 and 11 can be inserted. Cable sheaths made of metal are then soldered or smeared on the soldering stub 12. A heat cladding of the coils is also caused by improper execution of such soldering b / w. The lubrication connection remains minimal because of the large distance between the soldering point and the coil space. When installing the spool sleeve in a plastic cable, the soldering socket 12 is provided with a stuffing box or a transition fitting 13 known per se for PE cable jackets. The spool socket according to the invention is therefore also suitable for installation in pressurized gas-monitored cable runs.
