Large Power Transformers - Mitsubishi Electric

1 Large Power TransformersMitsubishi Electricis a leading manu-facturer of shell-form design transform-ers. The shell-form design is utilized forall Mitsubishi Electrictransformers larg-er than 120 MVA, of the 230 kV voltageclass and higher. The shell-form designoffers many benefits for these largerclass Power transformer ratings. Someof the advantages are: Compact, space saving design Excellent short circuit capability Excellent mechanical strength High design versatility Low losses Low noise level Efficient core cooling High reliabilityIn addition to our oil-filled shell trans-formers, Mitsubishi Electriccan alsosupply SF6 gas insulated transformersfor applications where a non-flammable,non-polluting transformer is desired,such as in densely populated areas,inside buildings, and in areas near lakesand rivers where potential oil leakagefrom a conventional transformer wouldbe harmful to the environment.

2 Other products we can offer are shuntreactors, phase shifters, split-windingtransformers, integrated transformersand special divided construction typetransformers. These special divided con-We are now proud to offer MitsubishiElectriclarge Power Transformers fordelivery to the US, building on over 80years of experience in the transformerindustry. Our high quality transformersare manufactured at the MitsubishiElectric Ako Works, located in Japan one of the most advanced transformersmanufacturing facilities in the Mitsubishi Electric Ako Workshasproduced Transformers with ratings upto 3000 MVA bank-capacity and 1050kV voltage class, and is a world leaderin research and development of tomor-row s transformer technology. Since1910, Mitsubishi Electrichas supplied atotal transformer capacity of more than740 million the US market, we are currentlyfocusing on providing Large powertransformers primarily of 300 MVA,230 kV and greater--where many of thebenefits of our shell-form design can berealized.

3 We also offer generator step-uptransformers for combustion turbine,combined cycle and other Power Keystone Drive, Warrendale, PA 15086 Phone:724-772-2555 Fax:724-722-2146struction type Transformers are used forapplications where size and weight lim-its of the transformer are restricted dueto certain transportation Electricalso supplies on-linedissolved gas analyzers (on-line DGA)for monitoring the level of combustiblegases present in the transformer insulatingoil. These on-line DGA devices can besupplied as part of a new MitsubishiElectrictransformer, or can be installedon any existing transformer that mayrequire monitoring of the combustiblegas levels present in the insulating DGA devices are also Transformers have providedtheir customers with Transformers featuring excellent performance and a level of high reliability proven throughmore than 80 years of operational performance and experience.

4 We willcontinue to be a leader in the developmentand manufacturing of Power Transformers ,supplying the largest, highest qualitytransformers to meet the ever-increasingneeds of the energy transmission anddistribution systems throughout the line cards LOW RES for PDFs 3/13/01 12:09 PM Page 1
