Abstract

A vacuum-insulated line (200) has an inner and an outer corrugated hose (101, 102) which are separated from one another by an evacuated intermediate space (103). One of the corrugated hoses is encased with a wound hose (201). The wound hose (201) prevents the line (200) from becoming elongated when it is charged with pressure during the transport of a medium. The wound hose (201) furthermore protects the line against external mechanical loads or damage. The wound hose simultaneously protects the corrugated hoses against excessive bending.
