We buy Hitachi Energy transformers from sellers across Virginia, including new-surplus units, equipment retired from service, and transformers left over after project changes. The brand identifies the manufacturer, but the nameplate tells us what you have: capacity, primary and secondary voltage, phase, frequency, cooling class, and serial number.
Hitachi Energy is the successor to ABB's power grids and transformer business, which became Hitachi ABB Power Grids in 2020 and Hitachi Energy in 2021. Equipment records may therefore carry different names. Our ABB transformer buying page covers equipment bearing that name. Virginia Transformer Buyers is an independent buyer, not affiliated with Hitachi Energy or any other manufacturer.
01Hitachi Energy Equipment We Buy
We buy Hitachi Energy large power transformers, substation transformers, distribution transformers, dry-type units, and cast resin transformers. Our buying scope includes single-phase equipment from 10 kVA and three-phase equipment from 15 kVA through MVA-class units. New-surplus and used equipment both belong in your inquiry.
For large power transformers, send every nameplate rather than only the main rating plate. Cooling stages, tap-changer details, bushings, and accessory identification can distinguish units with otherwise similar ratings. For distribution equipment, enclosure style, phase, connection, and voltage are central details.
- Power and substation units: include MVA ratings, ONAN/ONAF cooling stages, impedance, and tap-changer information.
- Pad-mount and pole-mount units: show kVA, primary and secondary voltage, and connection details.
- Dry-type and cast resin units: show insulation class, temperature rise, enclosure, and cooling designation.
- Failed or damaged units: describe the failure and show missing or damaged components for case-by-case review.
02Identify the Unit Beyond the Hitachi Energy Name
Start with a straight-on, readable photograph of the main nameplate. Include the manufacturer wording exactly as shown, serial number, manufacturing year if listed, and any separate order or drawing number. Do not substitute a purchasing description such as “ABB replacement transformer” for the actual plate information.
Capture kVA or MVA, phase, frequency, rated voltages, winding connections, impedance, and tap range. A plate showing 12470GrdY/7200 and 480Y/277 conveys information that “12 kV to 480 V” leaves out. Our transformer nameplate guide explains the fields to photograph when a plate is crowded or difficult to read.
For liquid-filled units, also photograph fluid information, total weight, and fluid quantity when listed. If the unit contains FR3 natural ester, report that from the plate or supporting records rather than guessing from appearance. PCB status must be disclosed and documented; a brand name or recent-looking enclosure is not a substitute for records.
03What Matters on Power and Substation Units
We pay attention to the complete rating and configuration, not just the largest MVA number. A transformer may have separate ONAN and ONAF ratings associated with natural-air and forced-air cooling. Show whether fans, radiators, control cabinets, and other listed accessories are present, removed for storage, or missing.
On substation transformer equipment, photograph the high- and low-voltage connections, bushings, cable boxes, and any attached switchgear interfaces. Identify a load tap changer separately from a de-energized tap changer. These details help describe the unit accurately without relying on a project nickname or an old equipment schedule.
Existing test reports and maintenance records help explain condition. Send dated reports tied to the serial number, including available ratio, insulation, winding resistance, or oil-analysis results. If a report references IEEE C57 standards, include the report itself and its test conditions rather than reducing it to “passed testing.” We do not provide engineering advice.
04Dry-Type, Cast Resin, and Stored Surplus Equipment
We buy Hitachi Energy dry-type and cast resin units as well as liquid-filled transformers. For dry-type transformer equipment, photograph the enclosure and visible winding area where safely accessible. Include temperature-rise ratings, insulation class, cooling information, and the voltage connection diagram.
Storage history matters for surplus equipment. Tell us whether the transformer stayed indoors, remained crated, or sat outside, and whether packaging or enclosure panels are missing. Describe visible moisture exposure, broken resin, damaged terminals, or corrosion rather than calling a unit “like new” without supporting details.
For unused equipment, include purchase specifications or factory documents if available, but identify the actual unit by its plate and serial number. Uninstalled does not automatically mean complete: fans, monitoring devices, bus connections, and loose-shipped accessories may be stored elsewhere. Photograph those items with the transformer inquiry.
05Virginia Projects and the South Boston Connection
Virginia sellers may have Hitachi Energy equipment from utility upgrades, industrial plant changes, commercial construction, renewable-energy projects, or canceled installations. We buy from every region of the state. A unit's present location and service history matter more to an inquiry than whether it originally came from a Virginia project.
Hitachi Energy operates a power transformer factory in South Boston, Virginia. In 2026, the company broke ground there on a roughly $457 million facility for large power transformers, expected to begin operations around 2028. That manufacturing presence is separate from our buying business and does not establish where an individual transformer was built.
For project surplus, separate installed equipment from spare or uninstalled units in your inventory. List each serial number, rating, condition, and location. A group described as “three Hitachi transformers” may contain different voltages, cooling configurations, or accessory packages, so individual identification prevents confusion.
06Prepare a Hitachi Energy Transformer Inquiry
To sell Hitachi Energy transformer equipment, send clear nameplate and overall photos, location, quantity, and condition notes through our offer form. We review the information and may ask about PCB documentation, test data, or site access. If the equipment fits, we send a written offer specifying price, freight, loading, and payment terms; pickup is scheduled with you, and payment follows those terms. See how the buying process works for details.
Describe access as carefully as the equipment: indoor or outdoor placement, loading restrictions, and whether accessories are already removed. We do not perform electrical disconnect work or ask sellers to drain fluid. Use your own qualified electricians to de-energize and disconnect equipment, and distinguish safely available equipment from units still serving a load.
Frequently asked questions
Do you buy transformers labeled Hitachi ABB Power Grids?
Yes, we buy transformers labeled Hitachi ABB Power Grids as well as Hitachi Energy. The business used the Hitachi ABB Power Grids name from 2020 and the Hitachi Energy name from 2021. Send the actual manufacturer wording, serial number, and ratings so the inquiry matches the equipment rather than a later company name.
Does a South Boston connection mean my transformer was built there?
No, a connection to South Boston does not establish where your transformer was manufactured. Hitachi Energy operates a power transformer factory there, but an individual unit needs its own identification. Send the nameplate and any manufacturing records available, and keep its current location separate from its documented place of manufacture.
Which MVA rating should I send for a Hitachi Energy power transformer?
Send all listed MVA ratings and their associated cooling designations. ONAN and ONAF ratings describe different cooling conditions, so quoting only the highest number leaves out important information. Photograph the complete plate and show whether the fans, radiators, and cooling controls associated with those ratings are present.
Can I sell a Hitachi Energy transformer with missing radiators or bushings?
Damaged or incomplete Hitachi Energy transformers are reviewed case by case. Identify every missing component and explain whether it is damaged, discarded, or stored separately. Overall photos, accessory photos, and the main nameplate help distinguish a dismantled unit with its parts retained from equipment that needs replacement components.
Do you buy unused Hitachi Energy cast resin transformers?
Yes, we buy unused surplus Hitachi Energy cast resin transformers. Send the ratings, connection diagram, manufacturing year if listed, and photos of the enclosure and visible resin surfaces where safely accessible. Include storage conditions and any visible cracking or terminal damage; unused status alone does not describe the unit's present condition.
Are you affiliated with Hitachi Energy or Virginia Transformer Corp?
No, Virginia Transformer Buyers is an independent buyer and is not affiliated with Hitachi Energy, Virginia Transformer Corp of Roanoke, or any other manufacturer. Brand names describe the equipment we buy, not a manufacturer relationship. Our transformer brands overview covers other manufacturer names sellers may find on their equipment.
