Haihong 110kV three-dimensional wound core transformer successfully closed at one time

        Recently, Haihong Electric's 110kV/40000kVA three-dimensional wound core power transformer was successfully closed at one time in a large-scale listed company Fenghua Hi-Tech project, and it was connected to the grid. This is another great achievement after Hanlan environmental waste incineration power generation projects. It demonstrates the advancement of Haihong's three-dimensional wound core technology, proves the feasibility of applying three-dimensional wound core technology in high-voltage and large-capacity fields, and fully demonstrates Haihong's three-dimensional wound core technology. Hong Electric's strong technical strength.

        Haihong Electric has been established for 22 years, and has always regarded technological innovation as the hard power for the sustainable development of enterprises. Haihong 110kV three-dimensional wound core transformer has invested nearly 90 million yuan since the project was established in 2013. It has completed the process from research and development, trial production, inspection to small batch production, and has a number of independent intellectual property rights, and has obtained 34 authorized patents at home and abroad. The project passed the appraisal of scientific and technological achievements in 2018. According to expert appraisal: the comprehensive technology of the project achievements has reached the international advanced level, and the indicators such as noise and loss are at the international leading level. The product has outstanding environmental protection performance, the noise level can be as low as 45 decibels and below, and the surrounding electric field and magnetic field strength is 200-250nT, which is only half of the traditional laminated core transformer. Compared with the national standard, the design value of the product reduces the no-load loss by more than 36%, the load loss by more than 18%, and the no-load current by more than 80%, which can save electricity costs for users and create benefits for customers.

        The use of Haihong products in key engineering projects of large listed companies is a high recognition of Haihong's advanced technology and recognition of three-dimensional wound core technology. At present, Haihong Electric is cooperating with Shenzhen Company to build Gaozhou Green Energy Environmental Protection Power Generation Project, Wuchuan Environmental Protection Thermal Power Plant and supporting facilities project, and continue to provide users with value-added products and services. World technology wins glory for the country. Looking to the future, Haihong Electric will make persistent efforts to gain a foothold in the domestic 110kV three-dimensional wound core power transformer market, closely follow the national "One Belt, One Road" strategy, and promote technologically advanced 110kV power transformers to the whole country and the world. , To provide the society with more green, energy-saving and environmentally friendly products, and to show the world the shining business card of "Made by Haihong Quality"!
