A 161 kV cable reel is an unusual thing to find in a yard. The Tennessee Valley Authority operates 161 kV as one of its working transmission voltages alongside 500 kV, and almost all of that network is overhead conductor on steel structures. Cable appears only where the line has to disappear: a station dip under a road, a segment into a gas-insulated switchyard, a crossing that cannot be flown.
Those jobs produce reels measured in hundreds of feet, not miles, and the cable itself is heavy enough that a single drum can be a lifting problem. Values are set by length, by voltage class evidence and by whether the cable can be reterminated, not by the metal inside it.

Why there is so little 161 kV cable about
Overhead transmission is cheaper to build and far easier to repair. A cable at this voltage needs a trench, a duct bank or a pipe, a thermal backfill design, and terminations that cost more than a span of conductor. It is chosen when there is no alternative, which means the total installed length in any one place is small.
The consequence for surplus is that most of what exists is already spoken for as spare. A utility keeps a length of the exact cable used on a critical dip, because a fault there cannot wait for a mill order. When such a spare is released it usually means the circuit was rebuilt or retired, and the reel has been in store for a long time.
How a 161 kV cable lot is identified
At this voltage the construction is unmistakable once the end is exposed. A large compact or segmental conductor sits under a semiconducting conductor screen, thick XLPE or paper insulation, an insulation screen, a metallic shield of wires or tape, and an oversheath. Diameters run large, and the cable does not bend to a small radius.
The jacket print and the reel tag carry the voltage class, the conductor size and the insulation thickness. Without them, capacitance and diameter measurements can narrow the class but not prove it. We do not quote a 161 kV reel on appearance alone, because the difference between this cable and a 69 kV construction of similar diameter is a matter of insulation wall.

What decides the offer on a short length
Length comes first. A 161 kV cable is only useful if the remaining footage covers the dip it was bought for, plus cutback at each end, so a remnant of 80 ft has a narrow market and a reel of 600 ft has a wider one. We ask for the tagged length and check it against the wraps still on the drum.
Condition comes second, and it is mostly about water and handling. Cable that sat with open ends, or was dragged over gravel on removal, is unlikely to pass a test at this voltage. Where a utility can supply the original test records, or a recent maintenance test, the reel is treated as verified and the offer reflects that.
Questions sellers ask
Is 161 kV cable made in three-conductor form?
Not in utility transmission practice. At this voltage the cable is a single shielded conductor per phase, installed as three separate lengths, often in separate ducts or in a trefoil arrangement. Three-conductor construction belongs to lower distribution voltages where the insulation wall is thinner and the cable is easier to handle.
How heavy is a reel of 161 kV cable?
Heavy enough that a single drum can exceed what a pickup or a small trailer will take, particularly at the larger conductor sizes. Plan on a boom truck or a crane and a low-bed, and check the reel's lifting points before the day of collection. We ask for the drum diameter and an estimated weight in advance.
Can a short 161 kV remnant be reused?
Only for a job that needs that length, and only if it can be reterminated by a crew qualified for the voltage. In practice most remnants go to a utility or contractor holding the same cable type as spares. Where the length is too short for a dip, the copper or aluminum conductor and the shield are recovered.
Do you need test records to buy this cable?
They help substantially. A factory test report or a recent field test tells a buyer the insulation is sound and supports a higher offer. Without records the cable is bought as untested, which means a discount for the risk that it fails a commissioning test after installation.
