R & D innovation

Be valuable only by creating value Creating value means be valuable.

Since its establishment, SHEMAR electric power R & D center has always adhered to technological innovation to lead the development of enterprises, with two national R & D platforms: National Key Laboratory of energy and Power Insulation Composites (National Key Laboratory [Guoneng science and Technology (2014) No. 393] approved on August 21, 2014), and post-doctoral research workstation; Three provincial R & D platforms: Jiangsu transmission and substation equipment composite external insulation engineering technology research center, Jiangsu Province (SHEMAR) power composite materials and equipment research center, Jiangsu Province recognized enterprise technology center. The State Key Laboratory consists of material technology research room, process technology research room, product development department, high voltage technology research room, pilot plant, comprehensive management department and intellectual property management department.

Over the years, SHEMAR power has always been guided by "solving industry problems and meeting market demand", based on the research of polymer materials, composite materials, high voltage insulation and structural mechanics, through material innovation, design innovation and process innovation, developed a series of new products of external insulation for power transmission (substation) and distribution, and widely used in the global power system. It has made outstanding contribution to the realization of the double zero of operation and maintenance cost and accident loss caused by external insulation in the field of transmission (substation) and distribution.

As of December 31, 2020, SHEMAR power has 240 domestic patents and 52 international patents. Participated in or led the formulation of 34 standards of State Grid Corporation of China, industry, China Southern Power Grid Corporation, and national and international standards. Won many national and provincial honorary awards.
