High voltage · 15 buying files
High voltage cable buying, 2 kV to 345 kV.
Transmission conductor, substation bus, shielded medium voltage and paper-insulated cable from utility rebuilds, plant distribution and decommissioned yards across North Texas.
High voltage lots are not warehouse clean-outs. They come from line rebuilds, substation upgrades, plant distribution replacements and utility decommissioning, and they arrive with paperwork, test history and a safety story that has to be right before anything is loaded.
This section covers the cable families above 2 kV and the conductor that hangs between structures. Every file is written for the person who has to dispose of the lot responsibly — a utility engineer, a plant electrical superintendent, an EPC contractor closing out a substation package.

01 Classes
The voltage ladder
Voltage class decides construction, and construction decides how a lot is reviewed. The same copper at 600 V and at 35 kV is not the same cable, and it is not handled the same way.
| Class | Typical construction | Where DFW produces it |
|---|---|---|
| 600 V – 2 kV | XLPE or EPR, single or multi-conductor, optional armour | Plant feeders, chiller and pump circuits, large service laterals |
| 2 kV – 15 kV | Shielded XLPE or EPR, copper tape or wire shield, semi-con layers | Distribution feeders, padmount loops, campus primary |
| 15 kV – 35 kV | Heavy shielded XLPE or EPR, thicker insulation, jacketed | Utility distribution, industrial substation feeds, data centre primary |
| 69 kV | High grade shielded cable, PILC or HPFF in older systems | Substation ties, legacy utility runs |
| 138 kV | PILC, HPFF or high grade XLPE with metallic sheath | Transmission ties and older urban ducts |
| 345 kV | HPFF, high pressure gas or extra high grade cable | Rare, utility transmission and large interties |
02 Overhead
Conductor that is not cable
Transmission lots are usually bare conductor rather than insulated cable: ACSR, AAAC, ACSS, copper weld and the optical ground wire that runs above them. These are bought on drum, reel and cut lengths, and the review hinges on stranding, code name, conductor condition and whether the drums are still sealed.
Optical ground wire and ADSS need a separate look because the fibre inside decides whether the drum has value beyond the aluminium and steel.
- Transmission conductor — bare overhead line conductor on original drums.
- ACSR and AAAC — the two constructions most often left over from rebuilds.
- OPGW and ADSS — optical ground wire and all-dielectric aerial cable.
03 Legacy
Paper, lead and fluid-filled cable
Older Dallas and Fort Worth systems still contain PILC and HPFF cable. Both are heavier, more specialised and more expensive to handle than XLPE, and both need a buyer who understands sheath condition, oil condition and the fittings that come with the run.
If a lot includes lead-sheathed cable, say so at the start. It changes the handling plan, the loading method and the paperwork.
Never cut, coil or load paper-insulated or fluid-filled cable before its isolation status and handling plan are confirmed. Read the medium voltage safety guide first.
04 Documentation
What a high voltage lot needs before review
A 15 kV reel with no history is a different proposition from a 15 kV reel with a test sheet. Buyers ask for the same four things on nearly every high voltage lot.
- Proof of isolation and de-energisation, and confirmation that the circuit is locked out.
- Test or commissioning records where they exist, including any hipot or partial discharge results.
- Drum tags, factory test certificates and the original cable specification.
- A handling plan: crane, reel trailer, drum size and weight, and the route a lowboy can take on site.
FAQ Seller questions
What sellers ask before they send a list
Answers describe how the buying desk works. They are not an offer, a rate or a promise of purchase.
What is the highest voltage you buy?
Files run to 345 kV for cable and transmission class conductor. Above that, lots are still reviewed case by case, but the handling, testing and transport requirements change enough that a conversation comes before any terms.
Do you buy decommissioned utility conductor?
Yes, subject to the utility's own disposal rules and to clear proof that the material has been released. Utilities often have scrap and surplus processes of their own; where a lot is released to the open market, it is reviewed like any other transmission drum.
Do you buy cable that failed a test?
Sometimes. Failed cable can still have value as a lot, but the failure has to be described honestly. A buyer needs to know what test failed, at what voltage, and whether the failure is in the insulation, the shield or a termination.
Can you handle lead-sheathed PILC?
PILC is bought, but it needs a handling plan. Lead sheath, paper insulation and oil content all affect transport and processing, and the lot has to be described accurately before pickup is scheduled.
Who confirms the cable is dead?
The owner or the contractor releasing the lot. A buyer will not accept a high voltage lot without confirmation that it is isolated, locked out and disconnected, and pickup is scheduled only after that confirmation is in writing.
Is medium voltage cable bought the same way as 600 V?
No. Shielded cable is reviewed on voltage class, insulation and semi-con condition, shield integrity and test history, where 600 V building wire is largely a copper-weight and footage review.
