Unit Substation Buyers
Complete primary-transformer-secondary lineups: incoming section, transformer, and low-voltage switchgear or switchboard bolted as one assembly. We buy them whole and we buy them by the section.
| Ratings bought | 300 kVA – 5000 kVA |
|---|---|
| Primary | 4.16 kV – 34.5 kV |
| Secondary gear | 480V switchgear, switchboards, MCCs |
| Configurations | Single-ended, double-ended with tie |
| Sections | Whole lineups or individual sections |
| Common brands | All major North American manufacturers |
Selling Unit Substations
Whole lineups are worth more than the sum
A double-ended 2000/2667 kVA unit substation with matched switchgear and a functioning tie breaker is a system somebody can reinstall. Split into pieces it becomes three separate used-parts sales. We will always quote the intact lineup higher, so tell us before your demolition contractor starts cutting.
Documentation raises the number
One-lines, schedule drawings, relay settings and factory test reports travel with the equipment and add meaningfully to what a downstream buyer will pay. If the drawings are in a plant engineering file, dig them out — that folder is worth money.
Splitting and rigging out
Unit substations are heavy, long and awkward, usually installed with no thought given to ever removing them. Our crews cut bus connections, split sections at the factory joints, skate them out and crate loose parts. We handle the wall openings and the cribbing. Freight and rigging are on us.

Other Equipment We Buy
Padmount Transformers
Pad-mounted distribution transformers are the single most liquid item we buy. A dead-front loop-feed unit in the 75 to 2500 kVA range with a legible nameplate and a sound tank can be priced from photographs the same day.
75 kVA – 5000 kVA300+ oil-filled units purchased annuallyOil-Filled Transformers
Liquid-filled units — mineral oil, silicone or ester — from 25 kVA pole-mounts up to 20 MVA power transformers. Oil is not a problem for us; containment, testing and disposal are part of what we do.
25 kVA – 20 MVA120–160 dry-type units handled per yearDry-Type Transformers
Ventilated, sealed and cast-coil dry-type units from 15 kVA control transformers up to 5000 kVA unit substation sections. Copper-wound units carry a materially higher offer than aluminum.
15 kVA – 5000 kVA40–60 substation-class units per yearSubstation Transformers
Station-class and power transformers from 1 MVA to 100 MVA, including units with load tap changers, radiator banks and conservator tanks. These are heavy-haul projects and we run them end to end.
1 MVA – 100 MVALots of 10 to 400 units purchased at a timePole-Mount Transformers
Single-phase and three-phase overhead distribution transformers, 5 kVA to 500 kVA. This is a volume item — we buy them by the pallet and by the trailer load out of utility and co-op surplus programs.
5 kVA – 500 kVA60–90 cast-coil units per yearCast-Coil Transformers
Epoxy-encapsulated cast-coil units built for harsh, humid and high-load environments. Because they were expensive new and are durable used, they hold value better than any other dry-type.
300 kVA – 10 MVASend the nameplate from your unit substations and we will return a firm number, usually the same business day. Payment is issued before loading and the rigging is ours.
