Zwischen Bleimantel und Eisenband kann noch eine isolierende Schichte bei der Fabrikation oder an der Verlegungstelle aufgebracht werden und ausserdem wird der Eisenmantel noch mit einer Rostschutzhülle in bekannter Ausführung versehen.
An Stelle eines geschlossenen Stahlbandes können auch deren zwei angewendet werden.
In Fig. 3. ist der Querschnitt eines Druckkabel mit drei Einzelleiterbleikabeln dargestellt und bedeuten s die Leiter, t deren Dielektrikum, b den Bleimantel über den isolierten Einzelleiter, wobei Druckkanäle v zwischen dem vorzugsweise sektorförmigen Bleimantel b und dem Dielektrikum t vorgesehen sind. An Stelle der in Fig. 3 angenommenen Rundleiter s können auch solche unrunder Form treten oder drei Einzelbleikabel werden einzeln zur Verlegungstelle gebracht, wo sie gemeinsam den Bandwickler passieren und mit dem Druckschutz i versehen werden. Da die Einzelkabel in bedeutend grösseren Längen zur Verlegungstelle gebracht werden können als dies bei einem zur Verlegungstelle gelieferten Mehrleiterkabel der Fall ist, so wird dadurch auch eine grosse Verlegungslänge des verlegten Mehrleiterkabels erzielt.
An Stelle der Einzelbleikabel mit sektorförmigem Bleimantel können auch solche mit zylindrischem Mantel treten, wobei die zwischen Druckschutz und Bleimantel entstehenden Zwischenräume mit Beiläufen ausgefüllt werden.
PATENT-ANSPRÜCHE :
1. Druckschutz für Hochspannungskabel mit unter Druck gesetztem Dielektrikum, dadurch gekennzeichnet, dass der Druckschutz aus einer oder mehreren geschlossenen Metallbandwieklungen besteht, die an der Verlegungsstelle beim Auslegen des Kabels aufgebracht werden.

An insulating layer can also be applied between the lead jacket and the iron tape during manufacture or at the point of installation, and the iron jacket is also provided with a rust protection cover of the known design.
Instead of one closed steel band, two of them can also be used.
In Fig. 3, the cross section of a pressure cable with three single lead cables is shown and s mean the conductors, t their dielectric, b the lead sheath over the insulated individual conductor, pressure channels v being provided between the preferably sector-shaped lead sheath b and the dielectric t. In place of the round conductors s assumed in FIG. 3, such non-round shapes can also be used, or three individual lead cables are brought individually to the laying point, where they pass the tape winder together and are provided with the pressure protection i. Since the individual cables can be brought to the laying point in significantly greater lengths than is the case with a multi-conductor cable delivered to the laying point, a large laying length of the laid multi-conductor cable is thereby also achieved.
Instead of the single lead cables with sector-shaped lead sheaths, those with a cylindrical sheath can also be used, with the gaps between the pressure protection and lead sheath being filled with fillers.
PATENT CLAIMS:
1. Pressure protection for high-voltage cables with pressurized dielectric, characterized in that the pressure protection consists of one or more closed metal band wieklungen which are applied to the laying point when laying out the cable.
