From June 24 to 26, 2026, the industry grand event in the Asia-Pacific region for coil, motor, and transformer manufacturing—the 2026 CWIEME Shanghai International Coil Exhibition—concluded successfully at the Shanghai World Expo Exhibition and Convention Center. With "High Tech & High Value" as its core theme, this year's exhibition brought together more than 330 industry leaders from around the world and attracted over 30,000 professional visitors for exchange. It provided in-depth coverage across the entire industry chain, including insulation materials, magnetic materials, and intelligent manufacturing, while also proactively laying out emerging tracks such as the low-altitude economy and humanoid robots, making it a core hub for technical exchange and industrial matchmaking in the global electrical engineering field. Coinciding with its 40th anniversary, Rui'an Insulation presented its full-chain high-performance insulation material solutions at the exhibition.
During the exhibition, Rui'an Insulation's booth attracted numerous new and existing customers, industry technical experts, and industry chain partners to stop by for discussions, owing to its complete product matrix and customized solution capabilities. At this exhibition, Rui'an Insulation arranged its exhibits around a three-dimensional layout of "core substrates + scenario solutions + precision processing," comprehensively covering mainstream and cutting-edge application scenarios for electrical insulation.
In the core substrates segment, the company showcased high-end products such as high-temperature-resistant insulation films and high-dielectric composite insulation materials. Among them, its high-performance polyimide film can adapt to harsh operating conditions such as new energy equipment and industrial high-voltage equipment, maintaining stable dielectric performance and mechanical strength under continuous high-temperature and high-voltage environments, and effectively resisting electrochemical erosion. The high-thermal-conductivity composite insulation material adopts a three-layer composite structure design, achieving a dual performance breakthrough in insulation protection and heat conduction and dissipation. It can operate stably for the long term in a 200°C high-temperature environment, addressing the industry pain point that heat dissipation and insulation in high-power equipment are difficult to balance simultaneously. The entire series of substrates has passed UL certification and compliance testing such as RoHS and MSDS, meeting the material standards for international high-end equipment.
In the industry solutions segment, Rui'an Insulation showcased targeted solutions for new energy drive motors, solid-state transformers (SST), and wind turbines. In response to the industry development trend of 800V high-voltage platforms for new energy vehicles, its motor insulation solutions combine high voltage resistance, oil corrosion resistance, and lightweight characteristics. They can support the continuous high-load operation of drive motors and help automakers improve the power density of powertrain systems. For power equipment such as wind power and solid-state transformers, the solutions focus on long-term outdoor operating conditions and voltage fluctuation scenarios, strengthening material weather resistance and insulation lifespan, effectively reducing equipment operation and maintenance costs, and improving operational reliability.
In addition, customized processed products such as NOMEX processed parts, MYLAR processed parts, and fast-acting paper processed parts, as well as series of precision insulation films, were also unveiled simultaneously. This demonstrated Rui'an Insulation's full-chain service capability, from the selection of high-quality global substrates to precision molding and processing, enabling flexible matching of insulation components in different specifications and forms according to customer needs and meeting the differentiated customization requirements of multiple industries such as electronics, industrial control, and automotive. The full series of products and solutions on display won high recognition from professional visitors on site for their stable electrical performance, reliability under harsh operating conditions, and comprehensive supporting adaptability.
2026 marks the 40th anniversary of the founding of Rui'an Insulation. Taking advantage of this industry grand event, the company held a 40th anniversary celebration under the theme "Four Decades of Collaborative Growth, A Promising New Journey with Rui'an." Partners from home and abroad, representatives of core customers, and Rui'an Insulation's core team gathered on site to review the 40-year development journey together and witness the opening of a new stage of development for the company.
Standing at the new starting point of its 40th anniversary, we will continue to uphold our original aspiration for quality, protect the safety and efficiency of electrical insulation with a more mature product matrix and full-process supporting services, and support the high-quality development of downstream high-end equipment industries. We look forward to meeting old and new friends again at the next CWIEME Shanghai International Coil Exhibition and jointly painting a picture of the future development of the insulation materials industry
