Native American Transformer Services, Inc. has experience with many transformer manufactures, such as, ABB, GE, SPX (Waukesha), Hyundia, HICO, Delta Star, Niagara, Virginia Transformer, Mistsubishi, and Siemens to name a few.
These brands, however, do not encompass our full range of capabilities: we can work on almost any transformer, performing repairs as listed below.
With NATS engineering expertise combined with high quality suppliers, we can provide replacement radiator and/or cooler packages ready to install. Installation packages can include; installation drawings, radiators/coolers, pumps, piping, gaskets and hardware, or any combination of these items. In addition to supplying the parts, NATS can field install the equipment. If specifications and/or drawings are not available a technician/engineer can make a site visit to acquire any necessary dimensions and information.
Native American Transformer Services, Inc. maintenance service can work on all of your substation equipment.
This includes transformers, circuit breakers, switchgear, regulators, control cabinets, housings, and structures, to name a few. NATS experience includes everything from pad-mounted transformers through 765kV equipment.
Maintenance painting can minimize equipment downtime; repainting of radiators at the first signs of wear, may save you from the higher costs of radiator replacement at a later date.
As a full service maintenance supplier, we can incorporate painting into a contract with other repair work, saving you from hiring multiple contractors to accomplish a complete scope of work.
We can comply with your paint specifications or use our own. Paint can be applied by spray, brush or roller on the main tank and by flow coat on radiators. Surfaces are prepared in a number of ways depending on their condition: grinding, sandblasting, needle gun, phosphoric acid wash, degreasers, pressure washing, sodium hydroxide stripping of radiators and special rinse for salt removal. All unpainted surfaces are either taped off or bagged prior to painting.
NATS knows environmental regulations and how to comply. If lead exists in the paint, our crews have the proper protective equipment for working with lead paints. We can collect the wash water in order to do the job in an environmentally-friendly manner; our painting system then encapsulates the lead paint so it doesn’t get carried into the ground.
Our teams are experienced with some of the most common problems as listed below.
NATS can fix the leaking location(s) or at your request or completely regasket all transformer openings and reprocess the oil to put equipment back in good condition; the scope of our services is up to you our customer.
