Building having a metallic, electrically conductive tube, electrical line positioned in a tube of this type and metallic, electrically conductive tube for this purpose

A metallic, electrically conductive tube configured to install electric lines for an electrical power supply of a building in the tube, comprising:

• an electrically conductive and metallic tubular connection part having a continuous inner surface, a first plurality of indentations integrally formed in the inner surface, and a second plurality of indentations integrally formed in the inner surface, the first plurality of indentations being spaced from the second plurality of indentations;
• first and second electrically conductive and metallic tube sections which are connected to one another by the tubular connection part in an extension direction of the tube, the first tube section having first and second opposite ends, a first outer surface, and a first end section at the first end thereof, the second tube section having first and second opposite ends, a second outer surface and a second end section at the second end thereof, the first end section and the second end section facing one another, wherein the inner surface of the connection part faces and abuts against the first outer surface along a first overlapping section, the inner surface of the connection part faces and abuts against the second outer surface along a second overlapping section;
• the first plurality of indentations of the connection part being provided in the first overlapping section, wherein an electrically conductive connection between the first end section and the connection part is provided by compression and plastic deformation of the connection part in the first overlapping section along the first plurality of indentations and of the first tube section in the first end section, in which they adjoin one another directly and in a plastically deformed manner in a compressed state;
• and
• the second plurality of indentations of the connection part being provided in the second overlapping section, wherein an electrically conductive connection between the second end section and the connection part is provided by compression and plastic deformation of the connection part in the second overlapping section along the second plurality of indentations and of the second tube section in the second end section, in which they adjoin one another directly and in a plastically deformed manner in a compressed state.
