Abstract
The system serves to transmit electrical energy in conurbations. It has a gas-insulated cable (1) having at least one high-voltage electrical conductor (8) arranged in a pipe (101) filled with insulating gas. The gas-insulated cable (1) contains at least two underground cable sections (11, 12), which can be operationally interconnected at an installation point (5) accessible from the outside. Such a system is distinguished by high availability, is easy to maintain and can be produced in a method in which impairment of the infrastructure of the conurbation accommodating the system is largely prevented.
