We buy cable above 35 kV
The range above 35 kV is read on sheath, moisture barrier and documentation before metal content is discussed. A single reel carries a project worth of attention.

Six details are enough to start: what the cable is, how much there is, where it is and what condition it is in. Photos can follow by text or email.
Prefer to talk 954-740-1983Above 35 kV, cable is transmission material, and it is bought that way. The classes are 46 kV, 69 kV, 138 kV and 345 kV, in XLPE and EPR with metallic sheath, in lead-sheathed constructions and in HPFF pipe systems. Conductor sizes run from 500 kcmil to 2,500 kcmil and above on the largest classes.
This range sits outside ordinary industrial cable buying. A reel at this voltage is a documented asset with a sheath, sometimes a moisture barrier, and a history. The review is about whether that history survives, not about how much copper is on the drum or how the drum photographs.
Why the range is read as transmission
Above 35 kV the cable is usually part of a transmission or subtransmission circuit, installed in a duct bank, a tunnel or a pipe, and terminated by jointers who work to a different standard than a plant electrician. The material, the handling and the paperwork all follow from that.
That is why a single 138 kV reel gets more attention than a pallet of 600 V feeder. The reel carries modest recovery value next to a pallet of 600 V feeder, but far more as a reusable asset, provided the sheath and the ends are sound and the length is known.
Sheath, moisture barrier and the test record
The metallic sheath keeps water out and carries fault current. A lead sheath dents and creases and can be repaired, but a crease that has opened is a problem. A copper wire shield or a laminated moisture barrier is read the same way: intact or not, and where the damage sits.
Test records matter as much as the sheath. A reel with a factory test sheet, a sheath test after installation and a storage history is read with confidence. A reel with an open end, no cap and no record is treated cautiously, and the review says so rather than guessing.
Crane, lowboy and an underground dip
A large transmission reel does not move on a pickup. It needs a lowboy and a crane or a reel trailer at both ends, and the site has to allow the equipment in. Tell us the drum size, the weight class and the access before a pickup is arranged.
Removed cable from an underground dip arrives in lengths cut for the pull, often with the potheads or joints still on. Those terminations are noted and the cable is measured between cuts. A length that came out of a duct in one piece is the best case, and it is worth saying so.

Transmission dips and substation exits around Austin
Austin's bulk transmission runs at 138 kV, with 345 kV on the larger ties and 69 kV on the subtransmission that feeds older substations. Where a line goes underground to reach a downtown or campus substation, the cable is installed in duct and later replaced in kind.
Those dips are where surplus comes from, along with project spares held at laydowns on the SH-130 and SH-71 corridors. A rebuilt substation on the ERCOT system can release a reel that was never pulled, which is the cleanest version of this material.
Sellers ask
Can a reel with an open end still be bought?
It can, but it is read cautiously. An open end lets moisture into the insulation, and at these voltages that matters. The end is inspected and the storage history is asked for. A capped reel with a test record reads very differently from an open one.
Do you need the test records?
They carry a lot of weight. A factory test sheet and any sheath test after installation tell a buyer what the cable has been through. Without them the reel is still reviewed, but on condition alone, and the read reflects that.
How is a large reel moved?
With a lowboy and a crane, or on a reel trailer, depending on the drum. Tell us the size and the site access when you send the list. The handling is agreed before pickup is scheduled, and both ends need the right equipment.
