December 17 to 18, 2015, Jufeng shares (830818) and DuPont's Ministry of Defense Technology held in Jiangsu Wujiang "frequency conversion motor insulation system application technology seminar", participants from industry organizations, motor manufacturers and scientific research units More than 60, including the famous insulation technology expert Lei Qingquan academician and Shanghai Electric Academy, ABB motor, Siemens, Jiamusi motor, the Chinese Academy of Sciences vehicle energy systems, Shanghai Electric drive, space and other experts on behalf of the source.

       As we all know, the motor is the driving force of general machinery and power energy, with the inverter in the field of industrial control applications, the use of variable frequency motors are increasingly widespread. Due to the presence of the frequency converter in the variable frequency motor, the insulation system of the variable frequency motor faces the continuous impact of the high frequency spike pulse, and the performance requirement of the insulation system is also more demanding. The theme of this symposium is how to promote the performance and reliability of variable frequency motor insulation system, and promote the sustainable development of variable frequency motor insulation technology.
        At the seminar, JuFeng shares share the progress and achievements of the development of variable frequency motor insulation materials, including nano-modified corona enameled wire (lacquer), nano-modified corona polyester imide impregnated resin, corona resistant insulation Materials and other products, product-related technical level has reached the international advanced level. And in the General Assembly on the product presentation and the future of the promotion and application. Jufeng shares with DuPont (Shanghai) R & D Management Co., Ltd. to develop the inverter motor with corona insulation system, will greatly enhance the frequency of life and operational reliability of China's frequency conversion motor to promote the use of motor energy efficiency structure adjustment, environmental protection , Resource conservation is of great significance.
        Mr. Xu Weihong, Chairman of Jufeng Shares, said that since its founding, JuFeng has been adhering to the "we do not do motor, we let the motor do better" business philosophy, over the years focused on insulating materials and insulation systems research and development, manufacturing And service work, through independent research and development, production and application of a combination of continuous technological innovation for motor customers to create higher value and promote the upgrading of insulation technology. Jufeng shares has always been to technological innovation as the starting point, to promote the company's production and management continue to develop, with the DuPont Protection Technology Division of the strong cooperation in the process of ten years grinding sword, creating a number of insulation materials industry first: A scholar workstation, the first national recognition CNAS laboratory, the first insulating material of major national scientific and technological achievements into the project, breaking the monopoly of multinational companies technology to achieve a million kilowatts generating units and efficient inverter motor key insulation materials and insulation systems Localization, the company part of the product successfully entered the Siemens, ABB, GE, Vestas and other world-class motor enterprises. Recently, JuFeng company has successfully passed the NDRC state-level enterprise technology center assessment, build a better platform for technological innovation, the company's long-term development adds stamina.
