Whitfield County · VFD cable
We buy VFD cable in Dalton, Georgia
Drive cable is bought for its shield, so a torn shield ends the review. In a Dalton plant the shield is usually the first thing a refit damages.

01Why Dalton holds drive cable in quantity
Why Dalton holds drive cable in quantity
Tufting machines run on drives, and so do the pumps and fans on a dye range. Each drive has a cabinet, and the cabinets are grouped in an electrical room rather than spread across the floor. The cable that matters runs from the cabinet out to a motor somewhere in the plant, which makes the runs long and the routing awkward.
When a plant replaces drives, it usually replaces the cable with them, because the old cable was sized for the old drive and the shield was chosen for an older switching frequency. That refit pattern is where the material comes from.
02Shield integrity is the whole review
Shield integrity is the whole review
A VFD cable carries three power conductors, a symmetrical set of grounds and a foil and braid shield over the assembly. The shield is there to contain the high-frequency current the drive creates, and the grounds are there to give it a controlled path back. Damage either one and the cable stops doing the job it was bought for.
So the review looks at the braid coverage at the ends, whether the foil is torn back, whether all the ground conductors are present and how many there were to start with. Two or three grounds is normal; one is a different product.
- Braid and foil intact and still bonded at both ends
- All ground conductors present, not cut back for a smaller lug
- Jacket not crushed or cut through at a bend or a tray edge
- Print legible enough to confirm the voltage class and the standard
A VFD cable with a torn shield is not worthless — it is a conductor lot. Say which it is before the reel is loaded.
03What the jacket says about where it ran
What the jacket says about where it ran
Cable that ran in tray above a dye range has a different look from cable in a clean tufting aisle: discolored, stiff, sometimes swollen where it sat against a steam line. Interlocked armor or a continuously corrugated jacket points to a wet area where the plant expected washdown.
Heat damage is the one that ends a reuse review. A jacket that has hardened to the point of cracking at a bend has taken the insulation with it, and no test on the bench will put that back.
04Cut lengths and the refit pattern
Cut lengths and the refit pattern
Refit cable is usually cut, not reeled. A run from a cabinet to a motor might be under a hundred feet, and a plant that kept the offcuts has a pile of them in the electrical room rather than a reel in the store.
Those lengths are still worth listing if they are labelled by drive and the shield is intact. Bundle them by size and by ground count, write the length on each coil, and keep them apart from the full reels in the same store.

06Questions
Dalton questions
How do you confirm a cable is VFD cable?
By the construction printed on the jacket and by the grounds. Three power conductors, symmetrical grounds and a foil and braid shield over the assembly is drive cable, not tray cable.
Are cut drive lengths of any use?
Yes, when the shield is intact and the length is written on the coil. They suit short motor runs and are reviewed on size and ground count rather than on footage.
Does a damaged shield mean the cable is scrap?
It means the cable is no longer drive cable. The copper is still there and is reviewed on conductor content instead of on reuse.
