161 kV cable buyer in Knoxville, Tennessee
TVA keeps its headquarters and a dense 161 kV transmission system in Knoxville. We buy the shielded cable that comes out of station dips, short underground runs and contractor stock around Knox County.

Six details are enough for a first review: what the cable is, the metal, the size, the footage or reel count, the condition and where it sits. Photographs can follow by text or email. There is no fee and no obligation, and nothing moves until written terms are agreed.
A 161 kV cable is not a commodity reel. It is a shielded, heavy-wall construction with insulation thick enough that a short length outweighs a pallet of building wire, and it usually exists in Knoxville because a station needed a riser, a crossing or a tie to an underground section. Most of it sits in contractor yards and utility stores rather than on an open market.
That scarcity is the point of this page. A Knoxville seller holding 161 kV cable is usually holding one specific leftover: the tail of a station dip, a spare phase, or stock bought for a job that changed. We price it on conductor size, insulation wall, metallic shield and the accessories that travel with it, not on the diameter of the reel.
Send the tag and the cut end. That pair tells us more than a photograph of the reel.

Why 161 kV cable is built heavy
At 161 kV the insulation is not a jacket over a conductor, it is the cable. Extruded dielectric is applied in layers, usually cross-linked polyethylene, with semiconducting screens bonded to the conductor and to the outside of the insulation so no air sits where the field is strongest. The wall runs several times thicker than anything in distribution class cable.
Around that core sits a metallic shield, copper tape, wire or a combination, and an oversheath over it. The shield carries fault current and holds the field in, and it also makes the cable stiff. A 161 kV length will not bend to a small radius and will not tolerate being dragged across gravel, which is why station dips are laid in duct or on tray and lifted carefully when removed.
What a Knoxville store actually keeps
In practice a Knoxville store does not hold 161 kV cable as inventory. It holds terminations and lengths tied to a named circuit. The lot we see is therefore short: a few yards left on a station dip reel, one spare phase kept against a failure, sometimes a factory length never unwound because a project scope shrank. Nothing in that list was bought as stock, and that is what makes the lot easy to describe and hard to replace.
Ask what the cable was bought for. A reel tagged to a specific bay tells us the construction and the year; a reel with no tag means measuring the insulation and reading the shield. Terminations, stress cones and joints bought with the cable often stay in the same crib, and they matter to the price because matching accessories are harder to source than the cable itself.
How we review shielded cable before it moves
We start with the tag and the purchase record, then check the jacket for UV checking, cuts and crush marks. The ends matter more than the middle. A cable cut and left open takes moisture at the conductor, and a shield folded back and taped is evidence of how the length was handled. Footage comes from the tag where one exists, otherwise from a measured length.
Access sets the schedule. Knoxville station work runs through a utility gate with a badge list, a switching order and a safety briefing, so we plan the pickup around your outage window rather than sending a truck the same day. On contractor yards the constraint is lifting, because a 161 kV reel needs a spreader bar and a machine that can hold it steady while the tag is read.

Questions on this lot type
Does 161 kV cable ever come up as surplus in Knoxville?
Rarely as ordinary surplus. TVA's transmission system and the contractors who build for it generate leftovers tied to specific stations, so what appears is a short length, a spare phase or a reel bought for a job that changed. We treat those as project material and price them against the circuit they were bought for, not against scrap.
Will you buy a single short length of 161 kV cable?
Yes, if the construction can be established. A length under fifty feet is still worth collecting when the alternative is storing it for another decade, and we will quote it as its own lot rather than fold it into a larger pickup. Bring the tag, or let us measure the wall and read the shield.
What do you need besides the reel tag?
Photographs of both cut ends, a note of any accessories kept with the cable, the reel diameter and width, and the site contact who can authorize a gate pass. If the cable was terminated, say so, because a cut-back termination changes how much of the length is usable. A photograph of the flange stencil helps when the paper label has weathered away.
How is a 161 kV reel moved out of a station?
On a utility-approved schedule with an escort, a drum lifter or a crane, and a route agreed in advance. We do not cut a reusable length to make transport easier. If a reel has to be shortened to load, that is agreed in writing before anyone touches it, and the remaining length is recorded.
