Product details

Kudosworldgroup has three business modules: electrical equipment, mechanical transmission equipment and fluid control equipment. As the backbone of the group's electrical equipment module, it landed in China, mainly engaged in the production of transformer on load tap changer, independently developed products with sulfur hexafluoride on load tap changer as the core, and established Scheatlerr brand. The product line involves transformers of various voltage levels.

Adhering to the group's consistent concept of technological innovation, Huachuang Shengfa established an elite R & D team in the early stage of its establishment. At present, there are 68 engineers in the R & D center of the headquarters, including 12 senior engineers and 16 intermediate engineers in the R & D center of the electrical equipment department, who carry out real-time technical optimization and technical update of electrical equipment products, so as to lay a solid foundation for the technical leadership of products. In 2014, the headquarters introduced the advanced technology of German MR company. On this basis, the team devoted themselves to research, and finally successfully developed sulfur hexafluoride on load tap changer and won a number of invention patents. According to IEC 60214-1 type test and inspection standard of International Electrotechnical Commission, the test results are far better than the standard requirements. This has filled the scientific research gap in this field at home and even internationally. After the products were put on the market, they immediately made remarkable achievements in domestic and foreign markets.
