Research Strategy 

Permanent Group R & D center was established in 1998, design, prototype and test specialized in electrical fittings; electrical fittings study new materials, new processes, new technology; the development of resource-saving and environment-friendly new products. China Permanent Group established headquarters Technology Development Center (Yueqing), Shanghai Super (special) high R & D Center, Jiangxi copper and aluminum materials research and development centers in close connection with the three R & D management system, and the Huazhong University of Science and Technology, China Three Gorges University, Wenzhou University well-known institutions to establish a wide range of cooperative relations with more than 90 R & D team, including high-, intermediate engineering and technical personnel more than 50 people, electrical fittings industry in Zhejiang Province is the first provincial-level technology (R & D) center.

      Center has participated in the revision of the GB / T 14315-2008, GB / T 9327-2008 and other six national and industry standards, the cumulative commitment to complete more than 20 provinces (municipalities) level science and technology program, the quality of high-tech products and projects to catch up to fill the gaps 1, wherein the conversion of six national and industry standards, class-leading domestic level 6. Also access to municipal Science and Technology Progress Award 2, more than 30 national patents.

      UHP fittings to officially enter since 2002, in 2003 successfully developed a 500kV EHV series fittings and the smooth provincial identification of new products, breaking the monopoly of state-owned enterprises in the field. In 2008 the company continued to accelerate the transformation and upgrading of the pace, aimed against the world's highest voltage level of UHV fittings, successfully developed ± 800kV UHV DC transmission line supporting a total of 249 kinds of fittings by relevant national testing agencies testing, and in June 2009 successful bidder Xiangjiaba ~ Shanghai ± 800kV HVDC transmission line project months. The success of the project, marking the company's product mix from the era of ultra-high pressure into the UHV era that developed into existence from the low voltage distribution network fittings to UHV gold with full coverage of the company, thereby laying the leading companies in the industry position.
