The buying desk reviews surplus electrical wire and cable held in Houston and across Harris County — full reels from cancelled expansions, partial reels from maintenance outages, obsolete stock from a plant storehouse, and cut-offs from electrical contractors working the metro. Most of it is not scrap. A reel of 4/0 THHN with a readable tag and documented footage is inventory, and it is reviewed as inventory.
Houston lots tend to be technically mixed. One laydown yard can hold medium-voltage feeder cable beside tray cable, welding lead, instrumentation cable and ordinary building wire. That is workable, but only if the families are kept separate and the evidence travels with them: reel tags, jacket printing, conductor size, voltage class and an honest statement of how the material was stored.
Cable families we review here
Expect medium-voltage shielded cable from 5 kV to 35 kV, tray and VFD cable from plant drives, instrumentation and thermocouple extension cable, welding cable from fabrication, and large THHN/XHHW feeders from commercial work. Copper is dominant; aluminium appears in service feeders and utility-side distribution.
