A power delivery system for parked aircraft includes protective rings on the power cords. These protective rings protect the power cord jackets from wear and facilitate movement of the power cords across the ground. The rings may be configured for securement to the cable so as to compress the insulative jacket of the cable somewhat, thereby firmly maintaining the rings in place on the cable. The rings may be formed of two identical elements that are joined to envelope the cable. The rings may accommodate both round insulated cable, as well as bundled cable.

The invention claimed is: 1. An aircraft ground power delivery system comprising: a power cable assembly configured to be connected between a power supply and a parked aircraft; and a plurality of rings, each ring having an inner periphery and an outer periphery, the inner periphery of each ring being compressively secured to an insulative jacket of the cable assembly, the outer periphery of each ring at least partially supporting the cable assembly to raise the power cable from a support surface and to facilitate sliding movement of the cable assembly over the support surface. 2. The system of claim 1, wherein the cable assembly is generally circular in cross section, and the inner periphery of each ring has a circular shape generally conforming a shape of the insulative jacket of the cable assembly, and smaller than a nominal size of an outer surface of the insulative jacket. 3. The system of claim 1, wherein the cable assembly includes a plurality of individual insulated cables bundled to form a non-circular outer shape, and wherein the inner periphery of each ring has a non-circular shape generally conforming to the outer shape of the cable assembly. 4. The system of claim 1, wherein each ring comprises a molded plastic material. 5. The system of claim 4, wherein the molded plastic material comprises glass reinforced nylon. 6. The system of claim 1, wherein each ring comprises two identical halves. 7. The system of claim 1, wherein the inner periphery of each ring has ribs for engaging the insulative jacket of the cable assembly. 8. A power cable assembly protection device comprising: an aircraft power cable; and a ring having an inner periphery and an outer periphery, the inner periphery being configured to be compressively secured to an insulative jacket of the aircraft cable, the outer periphery being configured to at least partially support the aircraft cable to raise the cable from a support surface and to facilitate sliding movement of the cable over the support surface. 9. The device of claim 8, wherein the inner periphery is generally circular. 10. The device of claim 8, wherein the inner periphery has a non-circular shape generally conforming to a non-circular outer shape of a bundled cable assembly. 11. The device of claim 8, wherein the ring comprises a molded plastic material. 12. The device of claim 11, wherein the molded plastic material comprises glass reinforced nylon. 13. The device of claim 8, wherein the inner periphery comprises protruding ribs for engaging the insulative jacket of a cable assembly. 14. The device of claim 8, wherein the inner periphery comprises reinforcing ribs. 15. The device of claim 8, wherein each ring comprises two identical halves. 16. The device of claim 15, wherein each half comprises a locking member and a corresponding engagement opening. 17. The device of claim 15, wherein each half comprises one or more alignment tabs and one or more corresponding alignment recesses. 18. The device of claim 15, wherein one half is configured to be inverted relative to another half to form a complete ring. 19. A power cable assembly protection device comprising: a power cable; and a plurality of rings secured along the cable, each ring having an inner periphery and an outer periphery, the inner periphery being configured to be compressively secured to an insulative jacket of the cable, the outer periphery being configured to at least partially support the cable to raise the cable from a support surface and to facilitate sliding movement of the cable over the support surface. 20. The assembly of claim 19, wherein each ring comprises two generally identical halves and wherein one half is configured to be inserted relative to another half to form a complete ring. 21. The assembly of claim 20, wherein each half comprises protruding ribs for engaging the insulative jacket of a cable assembly. 22. The assembly of claim 20, wherein each half comprises reinforcing ribs. 23. The assembly of claim 20, wherein each half comprises a locking member and a corresponding engagement opening. 24. The assembly of claim 23, wherein the locking member comprises a cam surface and a locking surface, and wherein the engagement opening comprises an abutment surface, the cam surface resiliently deflecting the locking member when the locking member is inserted into the engagement opening, and wherein the locking surface and the abutment surface contact one another to prevent removal of the locking member from the engagement opening. 25. The assembly of claim 24, wherein the engagement opening comprises a recess for accessing the cam surface for deflecting the locking member for removal from the engagement opening.
