ACSR conductor · Harris County / Greater Houston
We buy ACSR conductor.
ACSR is the conductor most Texas linemen know by name. Aluminium strands over a steel core, bought on the drum, at the drum end, or in cut lengths pulled from a rebuild.
Aluminium conductor, steel reinforced. The aluminium carries current and the steel carries tension, which is why a span can run long and the sag stays predictable. In Texas it appears on distribution feeders, sub-transmission lines and older transmission sections, from small feeder sizes up to heavy designs like Drake and Grosbeak. It is the conductor most line crews spend their careers working with.
That steel core separates ACSR from every other overhead conductor, and it is the first thing a buyer looks at. It also changes how a drum is handled, how the conductor is graded and what happens when it reaches a stripper. Aluminium and steel do not come apart the way a single-alloy conductor does, and that single fact shapes the whole review.
How the steel core changes handling
A reel of ACSR is stiffer than the same size in all-aluminium. It does not kink as easily, it holds a coil shape longer, and it resists the small radius bends that ruin a soft conductor. That stiffness is an advantage on a long pull and an annoyance in a crowded yard.
Weight is the other difference. Steel is denser than aluminium, so an ACSR drum is heavier than an AAAC drum of the same diameter and length. On a part reel this matters at the loading end of the job, where a forklift may be rated for the weight but not for the reach.
The core also dictates what happens after collection. A mill buying mixed conductor has to deal with two metals in one strand assembly, and that is a cost. Reels with clean, identifiable ACSR and long continuous lengths avoid most of that discount, so say the code name if you know it.
Code names, strand counts and what the tag says
ACSR is specified by code name rather than by a size alone, and the names carry the strand pattern with them. Drake is 26 aluminium strands over 7 steel. Grosbeak and Rail follow the same logic at different diameters. A tag reading 26/7 tells a buyer more than a measurement taken across the conductor.
Strand counts appear on the tag, on the conductor print in some cases, and at the cut end. Count the aluminium strands around the core, note whether the core is a single wire or seven, and you have the construction. Galvanised core and aluminium-clad core look different at the end and are not graded alike.
- Code name and strand pattern, such as 26/7 or 54/7
- Core type: galvanised steel or aluminium-clad
- Nominal size and measured diameter
- Length on the drum and whether it is one continuous length
- Whether the reel is a full drum, a part drum or a loose coil
If the tag is gone and the print has faded, the cut end is still enough to work with. A photograph taken square to the end, with the strands lit from one side, is usually readable without any measuring.
Corrosion where you cannot see it
The steel core is the vulnerable part. Moisture that gets between the aluminium layers and the core has nowhere to go, and the corrosion product takes up more space than the metal it came from. On the outside the conductor can look sound while the core has already begun to swell. It is the reason used ACSR is graded on the ends rather than on the drum.
Houston makes this worse. Salt air near the bay, humidity that rarely drops, and the sulphur compounds that come with refinery and petrochemical operations all attack a bare steel core. Conductor that hung near the Ship Channel for thirty years shows that at the ends, if anyone looks. Salt is patient, and a core does not announce itself.
None of it disqualifies a reel. Corrosion at the core changes the grade and the basis, not whether the material is bought. Cut a short sample if the ends are sealed. A buyer would rather see a foot of conductor than read a paragraph about it, and that sample settles most arguments about construction on the spot.
Offering a used ACSR reel
Send the code name if it is known, the strand count if it is not, the approximate length and the condition at the ends. Photographs of the tag, the cut end and the drum flange cover the rest. Say whether the conductor has been in service or came off a drum that was never strung.
Say also where it has been stored. A drum that has stood upright on a rack under cover is a different proposition from one that has lain on its side in standing water for two summers. The first is reviewed as conductor and the second may be reviewed as recovery.
Volume rarely decides an ACSR lot by itself. One drum of Drake with a legible tag and a sound core is a straightforward review, while a dozen short coils of mixed sizes is a sorting job and will be treated as one. Both are bought. They are simply not the same kind of lot.
- Voltage class and the kind of line it came from
- Code name or strand pattern
- Footage remaining, and whether it is continuous
- Core type and the condition at the cut end
- Storage history and the loading equipment on site
ACSR that has been through a fire, or annealed by fault current, is graded as scrap. Mention it before a trip is planned.
Questions sellers ask
Do you buy ACSR with the steel core still in it?
Yes. The core stays in place. Removing it is a stripping operation and not something a seller needs to arrange. A buyer assesses the core at the ends and values the conductor on total metal content, with the aluminium and the steel both taken into account.
What does 26/7 mean on a conductor tag?
Twenty-six aluminium strands laid over seven steel strands. The first number is the aluminium layer count and the second is the core, usually seven wires in one bundle. It identifies the code name family and gives a buyer the strand geometry without measuring anything.
Is used ACSR worth collecting in short lengths?
Sometimes. A jumper loop of a few feet is a metal recovery item. Lengths that could be restring on a short span are reviewed as conductor. The break point depends on size and condition, so describe what you have and let the answer follow from it.
Can you collect ACSR from a yard outside Harris County?
Yes, where the volume and the access justify the trip. Give the nearest town, the road, the gate hours and what can load the drum. A single part reel at a distant yard is usually grouped with other stops rather than collected on its own.

Have this cable on the yard?
Tell us what is on the reel, where it sits and what condition it is in. A buyer reviews the lot, asks for photographs of the tag and the cut end, and comes back with a real answer — not a request to call a call centre.

- Footage, reel count or weight, and condition
