Wujiang Transformer Co., Ltd. (hereinafter referred to as: the company) was founded in 1970. In 2004, it was restructured from the state-owned enterprise Wujiang Power Water Conservancy and Power Equipment Factory to Wujiang Transformer Co., Ltd., and was relocated to Wujiang Industrial Zone in 2013, covering an area of 217,000 square meters. With a construction area of 158,000 square meters, it is an innovative high-tech enterprise specializing in the integration of development, production, processing, sales, technical consulting and technical service of transformers and complete electrical equipment. For more than 40 years, the company has made great progress, the economic benefits have made a qualitative leap, and the comprehensive ability of technological innovation has been rapidly improved. The company has: the ability to produce more than 300 varieties of 10kV ~ 1000kV, 50 ~ 1000000kVA, and the annual output of 200,000 MVA transformers; the industrialization of complete sets of electrical appliances and switching equipment; the reactors and special transformers have been successively invested in R&D, manufacturing and industrialization; Electrical installation design, service and engineering general contract; realize the integration and integration of power scheme consultation, power scheme design, power installation, and power preventive test scheme. The company's products are currently widely used in thermal power, hydropower, wind power, photovoltaic power generation, UHV, rail transit, aerospace, petrochemical, communications, high-rise buildings and other fields. It is one of the top three enterprises in the comprehensive strength of the national transformer industry, and the most domestic transformer variety. One of the main suppliers. The company has won the national enterprise technology center, safety production standardization first-class enterprise, technological innovation demonstration enterprise, intelligent industry demonstration enterprise, Jiangsu science and technology small giant enterprise, high-tech enterprise, Jiangsu quality credit AAA enterprise, Jiangsu famous brand, Jiangsu Provincial famous brand products, Suzhou Mayor Quality Award and many other honors. In 2013, the company's product ODFS-334000/500 single-phase self-coupling non-excited transformer created the record of the first domestic 500kV voltage level maximum capacity transformer to pass the sudden short circuit test; in 2017 ODFS-400000kVA/500kV transformer created the world's 500kV level maximum capacity The transformer has passed the short-circuit test record; in 2017, it provided the Southern Grid SSZ11-40000/110kV product and passed the high-to-medium, medium-to-low resistance sudden short-circuit test. The achievements made the company become a "dark horse" in the transformer industry. In the past two years, the company has continued to work hard and accumulate energy. Through the introduction of high-tech talents and continuous R&D and innovation, it has overcome technical difficulties, especially the successful research and development of 1100kV reactors and 1000kV and 1 million kVA transformers. Followers become the industry leader.

On March 21st, the dry change workshop held a shell installation skills PK competition, this competition is based on the first PK on the 14th, the second competition held for two consecutive weeks. In this competition, Mr. Shen personally led the production, technology, quality inspection and other departments to the scene, and gave guidance on the process flow and specific component design of the dry transformer casing installation. Mr. Shen pointed out that this competition was conducted on the basis of doubling the workload last week, which is equivalent to the speed of long-distance running is faster than that of sprinting, which is commendable. As long as we use our brains, we can improve the breakthrough and surpass the benchmark. This competition has also set an example for other departments to carry out PK competitions. Next, we must further improve the management level, improve the level of technology and technology, promote innovation, enable employees to grow faster, create more value, and strive for the full realization of the leader in the transmission and transformation industry. In this dry-transformation shell installation competition, there are 2 people in each group, and 10 shells are installed, which has doubled the workload compared with last week. The competition is more fully planned, the requirements are more clear and more challenging, the relevant departments go to the field to be cheerleaders, to inspire them, quality inspection, technology and production management are tracked throughout the process. This is an opportunity for us to learn and improve. It is also a good opportunity for technological improvement, quality improvement, cost reduction, and efficiency improvement. It is also a rare opportunity for management progress, innovation, and talent growth. Next, we will go through the review, further planning, and further improvement, put forward clear requirements for quality, and train the process. The result of this skill PK competition starts from 7:00 in the morning, the first group ends at 1:30 in the morning, takes 16.5 hours, the second group ends at 2:20, it takes 17.33 hours, and the average time is 16.92 hours. The overall efficiency is 30% higher than usual and 18% higher than the previous PK. We have to summarize, improve the process flow, avoid some unnecessary processes, so that the efficiency can be further improved, to achieve our goal of increasing production and efficiency. The workshop and production department will choose to commend and reward the winning team in this competition.
