Line arrangement, connection arrangement and energy transmission system

A line arrangement comprising:

• an electrical line which has at least one electrical insulator and at least one electrical conductor which runs at least in some sections adjacently to the electrical insulator along a longitudinal axis of the electrical line, and
• a passive heat dissipator which runs at least in some sections along the longitudinal axis and which has at least one heat-absorbing surface portion and at least one heat-emitting surface portion thermally connected to the heat-absorbing surface portion,
• wherein the heat-absorbing surface portion is brought towards the electrical conductor at least to such an extent that the heat-absorbing surface portion enters into a thermally operative connection to the electrical conductor in order to dissipate waste heat of the electrical conductor to the heat-emitting surface portion,
• wherein the heat dissipator has a plurality of lugs spaced from one another along the longitudinal axis, which form the heat-emitting surface portion, and which branch laterally from the at least one heat-absorbing surface portion,
• wherein the heat-absorbing surface portion of the heat conductor extends along the longitudinal axis at least substantially over the entire length of the electrical conductor.
