Control and instrumentation cable buyers in Oklahoma
Instrumentation cable carries signal, not just power, and that changes how it is specified — shielding, pairing, drain wires and jacket material all matter. It is also the category most often mispriced by general scrap buyers.
Control cable is typically multiconductor, 600 V, with 16 to 10 AWG conductors, shielded or unshielded, used for motor control and interlocking. Instrumentation cable is usually 300 V, twisted pair, individually or overall shielded, with a drain wire, used for analogue signals in process plants.
We buy both, along with communication and thermocouple extension cable, from refineries, chemical plants, research facilities and manufacturing operations across Oklahoma.

Specifications at a glance
| Item | Detail |
|---|---|
| Voltage rating | 300 V instrumentation; 600 V control |
| Conductor sizes | 16, 18 and 20 AWG typical for instrumentation; 16–10 AWG for control |
| Construction | Twisted pairs, triads, multiconductor; foil or braid shield |
| Formats | Reels, partial reels, cut lengths |
| Condition | New surplus preferred; removed cable assessed for jacket and shield integrity |
What to send with the request
- Pair or conductor count and whether the shield is foil or braid.
- Drain wire presence and conductor size.
- Jacket material and whether it is rated for sunlight or tray installation.
- Whether the cable was installed in a process area, and any chemical exposure.
Not sure of the type?
Send a photo of the jacket print anyway. Reading a wire label is the one thing we do all day, and it is faster than guessing.

Control and instrumentation: seller questions
Do you buy instrumentation cable by the pair count?
Pair count, gauge and shield construction are the identifying details. Send the jacket print and the reel label if either is available.
Is removed control cable acceptable?
Sometimes. Shield integrity and jacket condition decide it, so describe how it was removed and stored.
Adjacent wire types we also buy
Armoured and tray-rated cable is where commercial and industrial surplus overlaps: the same job can leave behind coils of MC for a retail fit-out and reels of TC-ER for a plant expansion.
Low voltage cable is small, light and easy to store — which is why so much of it accumulates in boxes on a shelf until someone finally clears the shop.
Flexible cable lives a harder life than building wire. It is dragged, coiled, exposed to oil and sunlight, and replaced long before the conductor is finished — which is exactly why condition matters more than length.
