Abstract
A flexible, electrically heatable hose having an elongated electrical conductor which extends in the helical shape in the hose direction is illustrated and described. The object of providing a flexible, electrically heatable hose in which uniform heating over the hose length is ensured even in the event of major deformation of the hose, is achieved by a hose which has an elongated electrical conductor which extends in a helical shape in the hose direction, wherein the electrical conductor is embedded in a braid. In this case, the braid has first and second strands, wherein the first strands extend in a helical shape in the hose direction in the same winding direction as the electrical conductor, and the second strands extend in a helical shape in the hose direction in the opposite winding direction to the electrical conductor. The pitch angle of the electrical conductor, which extends in a helical shape in the hose direction, of the first strands and of the second strands is in this case between 50° and 80°.
