Substation wire and bus buyer in Albany

What the Albany lot actually contains

Station service cable is the backbone of it: 5 kV and 15 kV shielded constructions feeding transformers, switchgear and station batteries, usually in short lengths because a station is a small place. Control cable is next, multi-conductor, shielded, in sizes from 16 AWG up, and often cut into runs of a few hundred feet that match a specific circuit and nothing else.

Grounding conductor is the least glamorous and the most consistent. Bare copper in sizes from 2/0 up to 500 kcmil, sometimes stranded, sometimes solid, and often with exothermic weld stubs still attached at the ends. Those stubs are a condition signal: cut them off and the conductor is reusable, leave them on and the buyer is pricing around them.

Then there is bus. Aluminum tube in schedule 40 and heavier wall, with welded fittings, flanges and clamp-type connectors, is standard in a station yard and almost worthless as scrap relative to what it is worth as bus. It only keeps that value if the tube is straight, the ends are square and the alloy is known, which is exactly what the project documents record.

Voltage class is the field that gets guessed most often. Station service cable is marked on the jacket, control cable rarely is, and bus carries no marking at all once the tag is gone. Measuring the insulation wall and reading the jacket legend is what separates a 5 kV cable from a 15 kV one, and that difference decides whether a reel can be used in a station at all. Where the schedule survived, the question is already answered.

• Station service cable, 5 kV and 15 kV shielded, short lengths matched to circuits
• Multi-conductor shielded control cable, 16 AWG and larger
• Bare copper grounding conductor, 2/0 to 500 kcmil, with or without weld stubs
• Aluminum tube bus, schedule 40 and heavier, with fittings and connectors
• Cable schedules, as-builts and test sheets where the project produced them

Documents, loading and the public-work timetable

On a public project the cable schedule is the single most useful document a seller can hand over. It ties a reel to a circuit, a circuit to a voltage and a voltage to a test. Where it survives, a part reel of 15 kV station service cable can be sold as material for station work. Where it does not, the same reel is priced on copper content, and the difference is substantial.

Loading is straightforward by New York standards. Albany sits on I-90 and I-87, with I-787 running down to the port and CSX and Norfolk Southern serving the industrial districts. Station lots are light enough for a straight truck or a liftgate, which is often the practical answer when the material is in a basement switchgear room rather than a yard.

The timetable is set by the project, not the buyer. Public work has a substantial completion date and a close-out process, and material is usually released only after the punch list is done and the site is handed over. Planning collection around that date is more realistic than asking a site manager to move reels early.
