Corrosion: Reading Rust on a Transformer Cabinet
A working guide for Ohio sellers: what decides the number and how the unit leaves.
What we buy
What we buy here
Corrosion: Reading Rust on a Transformer Cabinet is one of those subjects where the wrong assumption is expensive and the right one takes ten minutes. Paint is a cosmetic question, and seam rust is a structural one, and the two are often confused. Most of what a buyer needs to know is stamped on a plate the size of a postcard.
The sequence matters: identify, inspect, document, then move. A buck-boost unit is almost always misapplied rather than worn out, and the diagram inside the cover explains why. Nothing about a transformer improves by waiting, and the oil in particular gets worse rather than better.

The form on this page, a text or an email all reach the same desk. Include the city, the access and any deadline the site is working to.

Review the offer
A buyer reads the photographs, asks one or two questions and sends a written offer with the assumptions stated, so nothing changes on the day.
- 04
We schedule freight
Crane, flatbed and permits are booked around your access. You get a date and a window, and we carry the cost of getting it right.
- 05
Testing on arrival
Winding resistance, megger and turns ratio, plus oil analysis where the unit is liquid filled. The results decide the final number, and you see them.
- 06

Pre-1979 units get the testing and the manifest they need.
Guide
The three kinds of rust
Surface rust is cosmetic, sits on the paint and comes off with a wire brush. Pitting rust has begun to eat the steel and is measurable with a depth gauge, which matters on a tank wall. Seam rust has entered a weld or a gasket line, and that is the kind that ends a unit's life.
A buyer's first question is about the rating and the second is about the access, in that order. A yard with a dozen units in it is a record of what Ohio plants have been replacing.
Where it starts
The base of a padmount collects water and road salt, so the bottom six inches tell you most of the story. Radiator fins trap moisture and debris, and a rusted fin bank loses cooling capacity before it loses oil. Bushing pockets and door seals are the other two places where water gets in and stays.
A quick decision is a kindness when the unit is standing in the way of a project. A seller who sends four photographs at the start usually gets a decision the same day.
What it does to value
Cosmetic rust costs nothing and should not move an offer. Seam rust on a tank bottom moves a unit toward scrap, because a repair means a tank job. Rust on a cabinet door matters less than rust on the cabinet frame, because the frame carries the load.

Where does a seller start with corrosion: reading rust on a transformer cabinet?
Pitting rust has begun to eat the steel and is measurable with a depth gauge, which matters on a tank wall. A mine-duty unit is designed to be dragged, and it looks it, which is not the same as being worn out.
Payment
Is corrosion: reading rust on a transformer cabinet part of what a buyer checks on site?
A pad that drains, a cabinet that is closed and a coat of paint every decade will keep a unit alive far longer than the winding needs. A pad that drains, a cabinet that is closed and a coat of paint every decade will keep a unit alive far longer than the winding needs.
