ABSTRACT:
Spacer for concentrically disposed tube systems where a temperature drop exists between adjacent tubes. This may consist, for example, of a superconducting electric cable or alternatively of a tube system for carrying heated liquid or gaseous media. The concentric tubes are spaced by a winder which touches the surfaces of adjacent tubes at particular points and which consists of two ribbons of insulating material disposed adjacent to each other having two elements in-between, and one of them being wound about the other so that they touch adjacent ribbon surfaces only in isolated points.
