The world's largest combined transformer in August 9, 2006, a group of Guangxi Longtan water conservancy project produced 78 million KVA, 500000 volt world maximum capacity of three phase combined transformer, in Shenyang Transformer Group Limited company to split the transport way shipment.
    According to introduction, the Longtan water conservancy project in the Guangxi area, traffic is restricted, the large capacity transformer must first products to solve the transportation problem. Shenyang transformer group limited design through a three-phase combined, separated transport, on-site assembly in three as a way of, not only for the transportation of products to find a successful solution, but also reduce the earthwork volume, reduce project cost.
    The first homemade±500kV DC transformer June 28, 2006 first homemade± 500000 volt DC transformer a success of the trial, the transformer is change as national key projects -- Guizhou to Guangdong second back HVDC transmission project ( abbreviation of Guiyang-Guangzhou two engineering ) converter system. Is for electric Limited by Share Ltd and Germany Siemens company joint design, subcontract production yield fruitful results, marked for the successful introduction of digestion, absorption, the converter transformer design and manufacturing technology, for our country to further realize the HVDC transmission engineering converter transformer used for localization of the foundation. According to the change of market department concerns chief introduction, this transformer height ten point nine meters, four point five five meters wide, four point eight five meters high, weight two hundred and sixty-eight tons, the total weight of three hundred and eighty tons.
    The world's largest capacity of dry-type transformer in 2006 at the end of 1, by special electrical design and manufacture of the world's largest capacity of dry type transformer SCZ925000 / 35 / 10.5 passed the " bear sudden short-circuit capacity test " of all the routine, type and special tests, product of the technical indicators have reached or surpassed the contract technical requirements. Thus, special electrical lasted nearly six months of major product development project was a great success.
    It is reported, this station is currently the world's largest capacity of dry-type power transformer, is suitable especially electric limited company for the Shanghai Pudong Airport expansion project one of the products offered by. The success of the project operation be not easily won. The company in 2005 June that project information, immediately by the marketing department takes the lead established project operation team, in the design, production, finance, logistics and other departments in the support, to the design, materials, production, cost and other work carried out in careful preparation of bids, the leadership of the company in the competitive situation and the needs of customers with accurate grasp, correct and decision-making through the bidding against strong opponents, in August 26th the same year to win the user's affirmative. But the signing of the contract only towards the world record, because the user asks the global first maximum capacity of dry type transformer must be in 2006 January to the National Transformer Quality Supervision and inspection center to complete the full set of tests, in such a short time to complete such a great new project, is a special electric group combat capability to span again
