Abstract: Self-damping bundle conductor spacer for maintaining apart suspended lengths of adjacently extending electrical conductors, including at least two opposed conductor clamps for clamping respectively a portion of the girth of a corresponding electrical conductor, each of the clamps being interconnected in spaced relation with the next adjacent clamp by a corresponding substantially transversely extending elongated helical spacer spring having a hollow axial bore, and a damping bundle of substantially parallel discrete flexible metal strands occupying substantially the cross section of the axial bore of a corresponding spring with the bundle strands in frictional surface contact with one another along their common extent yet relatively slidably displaceable with respect to one another and with respect to the confining portions of the spring along at least a portion of the extent of the axial bore in dependence upon tension and compression forces acting on the assembly.

Abstract: Conductor bundle arrangement comprising adjacently disposed conducting cable assemblies operatively interconnected to form a conductor bundle, each conducting cable assembly including an electrically conductive core, e.g. a helically laid multistranded core, having a composite substantially circular cross-sectional shape and a surrounding sheathing layer having a composite substantially annular cross-sectional shape with an exposed peripheral surface portion in the form of a multiplicity of helically oriented and adjacently disposed convex longitudinally extending arcuate ridges of progressively varying size, e.g. by providing said sheathing layer of varying diameter wires helically laid about the core in covering relation therewith, the sheathing layer including at each transverse section thereof at least one predetermined large size first ridge, e.g. wire, disposed at a first circumferential point and at least one predetermined small size last ridge; e.g. wire, disposed at a second circumferential point in diametric relation therewith, and a plurality of intermediately disposed ridges, e.g. wires, of progressively smaller sizes than that of the first ridge but larger than that of the last ridge adjacently disposed in the sheathing layer on each side of the at least one first ridge and occupying the remainder of the circumference thereof between said first and second points in corresponding substantially uniformly decreasing order of sizes in accord with the progressive peripheral remoteness thereof from the at least one first ridge, the exposed surface of the sheathing layer peripherally providing a composite silhouette characterized by a longitudinally repetitive variation in surface roughness around the circumference of the sheathing layer in accord with the helical disposition of the differing size ridges, e.g. wires, therein, the sheathing layer preferably being formed of round wires of size and disposition corresponding to said ridges and having a composite cross-sectional shape corresponding substantially to that of an eccentric annulus.
