VFD cable buying in Cleveland, Tennessee
Appliance manufacturing runs on drives, and drives get replaced. The shielded cable between a drive and its motor is a small, specific market that rewards careful sorting.

A variable frequency drive puts a switched waveform on the cable between it and the motor, and that waveform radiates. VFD cable exists to contain it: three power conductors, an overall shield, and a symmetric ground arrangement so current returning on the ground path does not form a loop. The construction is the reason the cable costs what it does.
Cleveland's appliance plants and their suppliers replace drives when a line changes or a unit fails, and the cable usually goes with the drive because the terminations are made up fresh. What comes back is a coil of shielded cable, often short, and frequently thrown in with ordinary tray cable. The coils are short but most of them have another job left in them.

What makes a cable a VFD cable
Three power conductors, each insulated, laid up with three bare ground conductors in a symmetric arrangement, then wrapped in foil and braided with tinned copper. The foil blocks high-frequency noise; the braid carries it and gives the cable mechanical strength at the terminations. Some designs add a drain wire in contact with the foil. A drain wire cut short is the most common defect on a used coil.
The grounds matter as much as the shield. Three grounds, one per phase, keep the return current balanced and stop the cable acting as an antenna. That is why a length of ordinary four-conductor tray cable is not a substitute, and why a buyer will ask about the ground count before anything else. Count the grounds at the cut end before you accept the reel.
Drive replacements and line changes
A drive replacement is a contained job. The old drive comes off the wall, the cable is disconnected at both ends and usually pulled out of the tray because the new drive wants a different length or a different termination. The pulled cable is intact but short, and its shield may be damaged where it was clamped. The drive frame size often tells you the cable size the job used.
Line changes are larger. When a conveyor or a process line is rebuilt, the motors move and the cable runs change with them. That produces longer lengths but more of them, and the ends are usually cut rather than disconnected. Keep drive change coils separate from line change reels; the first is a small-lot market, the second ordinary shielded power cable.
Why short shielded lengths are worth keeping
A fifty foot coil of VFD cable is useful. Drive-to-motor runs are short by nature, and a maintenance crew that needs to replace one will take a clean coil over opening a new reel. That is not true of unshielded cable, where short lengths are usually scrap, and it is why VFD shorts deserve their own pallet. That is a different market from ordinary shielded cable, and it prices better.
Check the shield at both ends before you coil. A braid cut back to the jacket and left to fray will need repair, and torn foil loses its function. Cable pulled hard through a conduit may have a stretched braid. Those lengths are still bought, but as shielded cable with a deduction rather than as new stock. A coil with a sound shield and a scuffed jacket is still good cable.

Questions on this lot type
How do I tell VFD cable from ordinary tray cable?
Look for an overall foil or braid shield, three ground conductors rather than one, and a print that names a drive or motor cable rating. Tray cable may have a ground and a shield, but a VFD cable has the symmetric grounds as well. The braid is usually visible at the cut end.
Do you buy VFD cable with a damaged shield?
Yes, with a deduction for the damaged section and for the repair a user would face. A short stretch of frayed braid near an end can be cut back and the length re-measured. Foil that is torn along several feet is harder to justify, and those lengths are priced closer to shielded scrap.
Is 1 kV VFD cable different from 600 V?
Only in rating, but the rating matters. A 480 V drive application is usually served by 600 V cable, and 1 kV cable appears where the specification calls for more margin or where the drive output is higher. The two should be tagged separately because a buyer will not mix them on one order.
What lengths are worth separating?
Twenty-five feet and up is generally worth keeping as cable. Below that it becomes patch material, and a coil of ten feet is only useful to a crew working on the same drive model. Keep the shorts in one box and the usable coils on a shelf so neither is searched for twice.

Drive cable left from a changeout?
Send the shield type, the conductor size and the coil lengths. We will price the shorts as their own lot.
