Bexar County ยท Port San Antonio
We buy surplus cable at Port San Antonio.
Hangar space is measured in acres of clear span, and the distribution feeding it is sized to match: 480 V feeder, long tray runs and generator cable for a bay that cannot go dark.

Reviewed by a buyerTell us what you have and where it sits. Nothing is moved until written lot terms are agreed.
Port San Antonio occupies the former Kelly Air Force Base on the southwest side, with aerospace maintenance, hangars and rail. The buildings were laid out for aircraft, which means clear spans, high bays and power pushed a long way from the service. A maintenance hangar needs 480 V at the door and lighting that reaches a tail height, so the runs are long and the conductor heavy.
Tenants keep arriving and reworking the same shells. A subdivided bay gets new distribution and the old feeder is abandoned in place or pulled to a laydown area, and door power, apron lighting and generator connections get replaced whenever a lease changes hands. Rail service means heavy material moves on a timetable that has nothing to do with a pickup truck.
01
What a hangar refit leaves behind
A hangar is a shell with a very large door, and almost everything inside it is replaceable. When a bay is reworked, door operators get new feeds, overhead lighting is replaced, and the distribution that served a paint booth or a test cell is disconnected, leaving removed feeder that is heavy, long and usually still on the reel it was pulled from. Note each run, its size, and whether it came out in one piece.

- Tray and MC on high steel
- Generator and transfer cable
- Apron and door operator power
- Bus bar and bare grounding
02
Why 480 V dominates and why it prices well
Large maintenance buildings distribute at 480 V three-phase because the loads are motors and hoists, and pushing that much power at a lower voltage would need conductor nobody wants to pull. The result is feeder from 1/0 past 500 kcmil, often aluminium and often in parallel sets, which is good news for a seller because identical runs pulled together are easy to document and easy to reuse. Keep the sets together and note which run is which.
03
Standby power cable from a site that cannot stop
Any site with aircraft in it runs on standby generation, and standby systems get upgraded more often than the buildings around them. A generator replacement leaves the old feeder between the generator and the transfer switch, plus the control cable that told it when to start, and both are bought. Ask the crew to disconnect at the terminals where there is time, because control cable is worth more than its weight suggests.
04
Getting onto the former base
Port San Antonio is a working industrial park with gates, tenants and rail crossings, so access is arranged rather than assumed. A truck needs a booked window, a driver who can clear the gate, and a destination inside the property with room to turn, so send the building number and the weight. Tell us who authorises the release from a leased bay, because that is usually the slow part.

Questions
Answers before you send anything.
If your question is not here, call the desk. A buyer answers, not a call centre.
Can a trailer reach the hangars, or is everything forklifted?
Both exist on the property, and it varies by building. Some bays open onto an apron a trailer can reach; others need material staged at a dock first. Tell us the building and we will ask the questions that decide the truck.
Do you buy abandoned feeder that was left in place?
Once it is actually disconnected and both ends are accessible, yes. Cable that is still terminated cannot be valued or moved. If your crew can free the ends and coil it, the lot is straightforward.
Is parallel feeder worth more kept together?
Yes. Identical parallel runs from one installation are easier to reuse and easier to document, so they hold value better than the same footage split into odd lengths. Tag each run and keep the sets on one pallet.
What documentation do you need from a leased building?
A release from whoever controls the space, plus the reel tags if they survived. Nothing leaves a tenant's bay without written authorisation, and that paperwork protects your crew as much as ours. Send it with the reel list and the pickup is straightforward.
