Wire from rubber, polymer and bearing plants in Akron-Canton

What heat does to a jacket first

Curing presses, autoclaves, ovens and heat-treat lines all run hot, and cable routed near them ages from the outside in. A jacket that has lived at elevated ambient for years goes hard, loses its print and cracks at a bend radius it used to take without complaint. Insulation underneath goes brittle. The copper is still there. Whether the cable can be reused depends entirely on how far in the damage runs.

High-temperature lead wire is the family built for that environment and also the family most often ordered in excess. Silicone and fibreglass constructions in the 18 to 10 AWG range get bought for one press or one oven, then sit on a shelf when the project changes shape.

Polymer plants, tyre plants, bearing lines

Akron's polymer and rubber work produces tray cable in bulk, because a mixing or compounding line is a long tray run with motors at intervals along it. Canton's bearing and specialty steel work produces feeder and control instead, plus welding cable from fabrication and maintenance shops. Forging and heat-treat add heavy power to induction equipment and the shielded cable that feeds it.

Stainless and alloy bar work adds another layer: mill-duty control that has been hosed, dusted and reheated, often on the same tray as the instrumentation.

• TC-ER tray from mixing and curing lines
• Silicone and fibreglass lead wire
• Feeder to induction and heat-treat
• Welding cable from maintenance shops
• 15 kV shielded to compressor substations

Canal-era buildings and crane bays

Akron's older plants are multi-storey, built when power came down from line shafting. Cable in those buildings runs in conduit through floors and in tray along the walls, and getting it out means working at height in a building that was never designed for a forklift. Canton's forging shops are the opposite: single-storey crane bays, rail service, one big door and a yard that turns anything.

CSX and Norfolk Southern run through both, and I-77 joins them. Where a shop has a crane, the crane loads the reels and the job takes an hour. Where it does not, and the building is four floors of masonry with a stair, the work is carried down by hand.

Chemistry, ratings and what to check

Chemical plants care about jacket compound for a reason, and a buyer should too. Cable that ran in a solvent or oil atmosphere can look sound and have a jacket that has absorbed something it should not have. A swollen jacket or a soft spot is a warning. Cable from a clean assembly area may be older and in better condition than anything from the process side.

Read the print for temperature and oil resistance, keep high-temperature lead apart from standard tray, and photograph any jacket that looks different from the rest of the lot. One odd reel in a stack is usually the one that tells you what happened.
