VFD cable buyer in Durham, NC
Drive replacement is where VFD cable comes from. A Durham plant changes an air handler or a process motor, the old shielded run is too short for the new location, and a reel goes on the shelf.

VFD cable in Durham
Variable frequency drive cable is a specific product with a specific job: carry a pulse-width modulated output from a drive to a motor without broadcasting noise into everything nearby. That means three power conductors, a symmetrical ground, and a shield — foil, braid or both — with a jacket that is usually heavier than the application first appears to need. It is bought in the sizes that match motor horsepower, and it is bought in the lengths that the drive and the motor happen to be apart.
The consequence is that VFD cable goes surplus whenever that distance changes. A drive moves to a new panel, a motor is relocated, a line is reconfigured for a different product, and the installed run no longer fits. What is left is a length that is too long for the new arrangement and too specific to be used casually. That is the material Durham generates, and it is worth more than its copper when the shield and the ground are intact.
The VFD cable in Durham sits in the research and pharmaceutical corridor along I-40 and in the laboratory buildings that have been converted or added to around downtown and the university. Those buildings are full of fans, pumps and chillers on drives, and they are also full of the documentation culture that comes with regulated manufacturing: submittals, cable schedules, as-built drawings.
That documentation is the reason a Durham VFD lot can be reviewed more precisely than most. If the cable schedule survived, the size, the shield type and the run length are all on paper. Where it did not, the jacket print still carries the voltage class and the conductor configuration, and the shield can be confirmed by looking at a cut end.
Why this material gets reviewed properly
The ground conductor is the tell
A VFD cable with three symmetrical grounds split into the interstices is a different product from a three-conductor cable with one reduced ground in the centre. The first is made for drive duty and holds its value as such. The second may be tray cable or motor lead cable being passed off as VFD. We check the ground arrangement before we accept the description.
Shield continuity and end damage
A foil shield creases and tears at the cut, and a torn shield at the end of a run does not necessarily condemn the length, but it does need to be trimmed back and inspected. Braided shields survive handling better. We look at both ends, because a length that has been dragged through a conduit and cut twice has two chances to be damaged.
Small reels, high value per foot
VFD cable is not usually a volume material. A 250 ft reel of 8 AWG four-conductor shielded cable is a meaningful lot on its own, and a hundred feet is still worth collecting. This is one of the few families where a short, tagged remainder is genuinely inventory rather than recovery, which is why the tag matters so much here.

Questions on this material
How do I tell VFD cable from ordinary motor lead cable?
Look at the ground and the shield. VFD cable will have a shield — foil, braid or a combination — and usually three symmetrical grounds rather than one reduced ground. The jacket print often names the construction and the voltage class, typically 1 kV or 2 kV. If the ground is a single reduced conductor and there is no shield, it is motor lead cable and should be described as that.
Do you buy VFD cable that has been pulled and then removed?
Yes, provided it is described as pulled. Cable that has been through a conduit has been bent, dragged and possibly cut, and that shows. It is still usable in many cases, but it is not new stock and should not be presented as such. A pulled length with clean ends and an intact shield is reviewed as a used length, not as scrap.
What lengths are typical from a Durham plant changeout?
Usually between 50 and 300 ft, because that is the distance between a drive panel and a motor. Longer runs exist where a remote drive feeds a rooftop unit, but they are less common. Anything under about 30 ft is generally a jumper, and we will say so rather than inflating what it is worth.
Can the cable schedule be used instead of a physical inspection?
It can shorten the process, not replace it. A schedule tells us what was specified and installed; it does not tell us what condition the cable is in now. We will use it to prepare, then confirm size, shield and length on site. Where the schedule and the material disagree, the material wins.
