SUBSTATION TRANSFORMERS
T&R Electric offers single and three phase substation transformers. Our transformers have up to a 30 MVA base and voltage ratings up to 138 kV. We can build any configuration for your distribution system.
T&R Electric can also repair your existing substation transformers. First, we evaluate your transformer, and determine what problems may exist. We will then repair your unit quickly and efficiently. Our goal is to get you fully operational as quickly as possible. If you need a rental while your unit is being repaired, or in case of emergency outage, we can provide that too.
Here are a few of our transformer design features:
● All winding materials are 100% copper
● Designs include circular disc, helical, and layer windings
● Short circuit analysis performed on all designs
● Coil blocking structures maximize short circuit strength
● Improved lead structure support
● Upgraded steel clamps
If you are looking for a single or three phase substation transformer, contact T&R Electric. Ask us about repairing your existing transformers, too.
"The City of Springfield lost power when a squirrel created an arc that caused the failure of a 10 MVA substation 69000 Delta-12470Y/7200 and a bank of 333 KVA regulators. I called T&R Electric and they had a rental 10 MVA and a bank of regulators on site in less than 24 hours. They picked up our failed transformer and rewound it in a timely manner while we used their rental. We have always had great service and continue to buy all of our transformers from T&R Electric Supply."
