Covered conductor buyers in Tennessee
Covered overhead conductor from utility vegetation programs, bought on cover condition, voltage class and footage rather than on metal content. Most of it arrives from programs that ended, in one or two sizes, often still tagged.

Vegetation management runs as a program with its own budget, its own crews and its own material. Where a utility decides to stop trimming on a fixed cycle and cover the conductor instead, the store room fills with tree wire in 15 kV and 25 kV classes, and bare conductor starts coming off the line.
Covered conductor is bought and sold on the cover. The conductor underneath is ordinary aluminum or ACSR. What makes it a different product is the layer over it, which is why a reel with a damaged cover sits closer to scrap than its metal content would suggest.

What covered conductor is and is not
Covered conductor carries an extruded layer of XLPE or HDPE over the conductor, thick enough to withstand occasional contact with a limb and to cut down faults when a branch lies across a span. It has no metallic shield, no concentric neutral and no jacket over the insulation, so it is not a cable and should not be treated as one.
The cover is not rated for direct burial and does not make the line safe to touch. Crews treat it as energized. That distinction matters at resale, because a buyer expecting shielded cable will find the covering too thin for the application and the assembly missing the shield entirely. Cover is not a substitute for clearance, and no utility treats it as one.
Cover thickness varies with the class. A 15 kV covered conductor carries a thinner wall than a 25 kV one, and both are thinner than a shielded cable of the same voltage, because the cover is not designed to contain the field, only to keep limbs off the surface. A 25 kV reel cannot be substituted on a 15 kV specification without checking the hardware.
How vegetation programs create the surplus
A program begins with a section of line, a specification and a purchase. The utility buys covered conductor in the sizes that line needs, crews install most of it, and the remainder becomes program stock until the program ends or the standard is revised. Then it turns into surplus in a single block rather than reel by reel.
Program surplus is unusually coherent. The reels tend to be one or two constructions in a few sizes, bought in the same period, often still tagged. That makes it easier to place than a general store room lot, provided the cover has been stored out of direct sun and the drums have not been stacked on their sides.
Telling covered conductor on a reel
The print on the cover normally says covered or tree wire, along with the voltage class, the size and the standard. If the print has worn, look at the end. Covered conductor shows one thick wall of black or colored insulation over the strands, without the thin semiconducting layers and copper tape a shielded cable would show.
Cover condition is the value question. Sun cracking, chalking and abrasion through to the conductor are reasons to discount. A cover that is scuffed but continuous is not. Bend a short length and look for cracks along the outside of the bend, which is where aged XLPE fails before anywhere else. A cover that has gone chalky over the whole wrap is the one to price down.
- One wall of insulation, no shield or neutral
- Print repeats the class and size
- Sun damage shows as cracking on the outer wrap
Questions sellers ask
How is covered conductor different from bare?
The cover. Bare conductor is strung as it comes off the reel and relies on spacing and trimming to stay clear of trees. Covered conductor adds an extruded layer that tolerates brief contact and reduces the fault current a branch can start. The conductor underneath is the same aluminum or ACSR either way.
Can covered conductor be used underground?
No. The cover is not a moisture barrier and is not rated for soil contact or for the mechanical loads of a duct pull. Using it in a trench would fail inspection and would shorten the life of the conductor. It belongs on spacers, pins or crossarms in the air, and nowhere else.
How do you check cover condition?
Look at the outer wrap first, since that is where sun damage starts, then unroll a few feet and bend it. Cracks on the outside of a bend or a chalky surface mean the polymer has aged. A cover that is dirty but flexible, with no cracks at the bend, is normally still serviceable.
Why do utilities buy tree wire at all?
Because trimming a line costs money every cycle and covering it costs money once. On sections where access is poor, where property owners resist cutting, or where the tree canopy closes over the line, covering the conductor reduces the number of outages a crew has to answer between trims.
