Schutzanspruches.Claim to protection.
Figur 1 zeigt als Beispiel den Schnitt durch ein abgewinkeltes Rchrgasj kabelstück. Die Hochspannungsleiter 1 liegen koaxial in den Rohrkapselungsteilen 2, gehalten durch die Scheibenstützer 3. Eine rechtwinkelig, Ecke im Verlauf des Rohrgaskabels wird durch das Winkelstück 4 gebildet. Zur Aufnahme von temperaturabhängigen Längsdehnungen des Hochspannungs- ;. leiters dient ein Dehnungsausgleich 5 mit Vielfachkontakten. Nicht gezeichnetAs an example, FIG. 1 shows the section through an angled Rchrgasj piece of cable. The high-voltage conductors 1 lie coaxially in the pipe encapsulation parts 2, held by the disk supports 3. A right-angled corner in the course of the pipe gas cable is formed by the angle piece 4. For absorbing temperature-dependent longitudinal expansions of the high-voltage;. conductor serves an expansion compensation 5 with multiple contacts. Not drawn
