Medium voltage cable buying in Spring Hill, Tennessee
The Spring Hill manufacturing complex and its suppliers run their own distribution, and every upgrade leaves shielded cable behind. We buy it by class, construction and footage.

A vehicle plant is a small utility. Power arrives at transmission voltage, is stepped down at plant substations, and then runs across the site at 15 kV or 25 kV to unit substations near the load. When a line is upgraded or a substation replaced, the cable between those points is pulled, coiled and left for whoever will take it.
That cable is where a plant seller usually misjudges value. It looks like heavy black hose, and it is often stacked with 600 V feeder that came out in the same shutdown. The two are not the same material, and the difference shows in the shield, the wall thickness and the print on the jacket.

15 kV against 25 kV, and why it matters
Both are shielded power cable, but the insulation wall is sized to the voltage. At a 133 percent insulation level a 15 kV cable commonly carries a 220 mil wall and a 25 kV cable a 320 mil wall, with semiconducting screens on both sides of the insulation. A 25 kV cable is visibly thicker at the same conductor size.
The class is printed on the jacket with the conductor size and the insulation level, and those three readings carry most of the value. Cable rated for 25 kV is not substituted onto a 15 kV circuit without an engineer's approval, and a buyer stocking for 15 kV work will not pay a 25 kV price. Read the print before you sort.
What a plant distribution upgrade leaves behind
A unit substation replacement produces cable in short runs: the ties from a transformer to a switchgear line-up, the feeds to a motor control center, the drops to a remote panel. These are made up on site from a reel, so the leftover is what the run did not need, usually between a few feet and a few hundred. A stores clerk can usually name the circuit faster than the cable can be measured.
Motor replacements add a second stream. A medium voltage motor change leaves the three leads and the shielded cable that fed it, often cut at the peckerhead with the lug still on. Terminations and stress cones that were never used stay in the electrical shop and are worth collecting with the cable, because a kit matching the cable class is harder to buy than the cable.
Judging a coil that has no tag left
Plant coils lose their tags. The jacket print is then the only authority, and it is often dirty. Wipe a section with a rag and read it under a light: manufacturer, size, voltage class, insulation, jacket and a date code. If the print has faded entirely, measure the wall at a cut end with a caliper and compare it to the class.
Then check the shield. A tape shield shows as a copper wrap under the jacket; a wire shield as a set of concentric wires; some cable uses both. A shield cut back unevenly means the cable was terminated on site, which is fine, but the exposed insulation at that end must be inspected for tracking and moisture before the length counts.

Questions on this lot type
Can 25 kV cable be used on a 15 kV system?
The insulation can withstand it, but the substitution is an engineering decision, not a stores one. Terminations, clearances and the switchgear rating all have to match. We price by the class printed on the jacket and do not encourage a buyer to treat a higher rating as a universal replacement.
How do you establish footage on a coil with no tag?
Weigh it and subtract the reel, then divide by the published weight per thousand feet for that size and construction. On a coil without a reel, measure the outside diameter, the inside diameter and the width, count the wraps, and multiply the mean circumference by the count. The two methods should agree within a few percent.
Do you buy cable with lugs still attached?
Yes. The lug is cut off before the cable is weighed, and it goes into the copper or aluminum scrap separately. The lug also tells us something: a compression fitting installed with the right die and not overheated suggests the cable was pulled out of a working circuit rather than a faulted one.
What about 5 kV cable from older motor circuits?
It is bought as its own class and should not be mixed with 15 kV material. Older plants often have 5 kV and 4,160 V circuits still in service, and the cable for them has a thinner wall that is easy to mistake for 600 V shielded cable. Print or a wall measurement settles it.
