400 MVA 500/22kV 1-phase GSU Delivery and Installation 4 October 2005 Mitsubishi Electric Manufacturing and MEPPI Project Management with Local Support Mitsubishi Electric is a worldwide leader in the technology of power transformers applied to nuclear power plants. More than 630 trans- former units at or above 500kV have been produced including 53 Genera- tor Step-Up (GSU) transformers presently installed on nuclear power generators. The transformer products of Mitsubishi Electric incorporate innovative thinking and customer-driven design with cost- ef@ cient performance.
If you are facing an aging transform- er A eet and are concerned about the reliability and power delivery of your nuclear plant, MEPPI can help. We would be glad to visit your facility to discuss transformer replacement options and our project management capabilities. Plan to upgrade your nuclear station 9s GSU transformer in ad- vance and raise your generating plant 9s reliability to the highest level of con@ dence.
Mitsubishi Electric 9s technologies and strong local MEPPI engineering and marketing support will be there whenever and wherever you need. Choose MEPPI. Mitsubishi Electric Japan The Ako works factory ... more. less.
Ako-city, Hyogo prefecture Japan Mitsubishi Electric Power Products, Inc.<br><br> Headquarters - Warrendale, Pennsylvania USA 684MVA, 230/25kV 3-phase GSU " Delivery and Installation: February 2005 Mitsubishi Electric Manufacturing Plant 4 the Ako works (Japan) of- fers nuclear generation GSUs based upon the shell-type design, which has been shown to exceed the perfor- mance of core-type for such high-de- mand applications. Bene@ ts include: High short-circuit withstand capability: The tank of a shell-form transformer is a cform-@ t d design that @ ts over the core. This enables the transformer to withstand high mechanical forces during an external short-circuit condition.<br><br> High dielectric strength.: In shell- form transformers, the pressboard materials that surround the coils subdivide the oil insulation into many small gaps. The oil-impregnated pressboard materials have a much higher dielectric strength than the oil gaps. This insulation design leads to a very high dielectric strength.<br><br> Ef& cient cooling capability: Shell-form transformers have an ef@ cient cooling capability due to the vertically arranged pancake coils. This allows the oil to easily A ow across the entire coil surface and cool the transformer. High reliability and ' exibility: About 98% of all Mitsubishi shell- form transformers supplied since 1960 are still in operation.<br><br> Mitsubi- shi transformers can be designed to physically match the existing shell- form transformers without the need to modify the existing foundations or Isolated Phase Bus low voltage con- nection points, if required. The Ako works specializes in produc- ing large MVA, high voltage shell- form transformers, and has vast experience in producing many of the world 9s largest transformers. Some other notable @ gures about Ako include: " Top 5 world manufacturer of large power transformers established in 1921, with production capacity of 33GVA per year " Around 100 units have been supplied to U.S.<br><br> customers in the past 6 years " Ako works is recognized world- wide as one of the cleanest, most-advanced transformer factories in the world, and is ISO 9001 certi@ ed " Very low failure rate " Excellent on-time delivery record Mitsubishi Electric Power Products, Inc. (MEPPI), located in Warrendale, PA, is responsible for all Mitsubishi Electric Corporations transmission and distribution electrical equipment in the U.S., including large power transformers. The primary point of contact between U.S.<br><br> customers and our factories in Japan is the MEPPI of@ ce. All technical and commercial com- munications would be handled by the MEPPI Substation Department 4 a fully staffed group of project managers, project engineers, project drafters, project purchasing, and ac- counting as well as other functions. A project manager is responsible for arranging and overseeing the local inland transportation and installation for the transformers in the USA.<br><br> A factory @ eld service engineer is present for installation supervision of the transformer. A transformer appli- cation engineer is on staff to provide technical support, assist the project manager, make any necessary site visits, perform inspections, and handle customer 9s service requests. <br><br>
