On November 22, 2024, at the "Accelerating the Construction of an Innovative Zhejiang, Developing New Quality Productive Forces Through Local Adaptation" Mobilization and Deployment Conference and the Provincial Science and Technology Awards Ceremony held in Hangzhou, the "Key Technologies and Industrialization of High-Efficiency Manufacturing for Low-Temperature Ceramic-Forming Insulated Fire-Resistant Cables," a joint project submitted by Zhejiang Yuantong Cable Manufacturing Co., Ltd. and Zhejiang Zhongda Yuantong Special Cable Co., Ltd., won the second prize of the Zhejiang Provincial Science and Technology Progress Award. This achievement became a focal point of the event, showcasing the profound technological innovation capabilities and sense of responsibility of Zhongda Yuantong Cable under the Zhejiang Materials Industry Group.
The project achieved significant breakthroughs in technological innovation. Its unique low-temperature rapid ceramic-forming flexible fire-resistant cable technology successfully overcame the key challenge of rapid ceramic formation at 750°C. The specially developed vertical magnesium oxide filling production equipment enabled large-scale production of rigid fire-resistant cables up to 10,000 meters in length, filling a domestic industry gap and achieving internationally leading technical standards. The project has obtained multiple domestic and international patents, including 1 U.S. invention patent, 1 German utility model patent, 6 Chinese invention patents, and 10 utility model patents, along with the publication of 2 academic papers.
In terms of industrialization, the project significantly enhanced production efficiency, achieving a 99-fold increase in production line output, a 15% cost reduction, and a product qualification rate of 99.5%. It marked the world’s first large-scale industrialized production of flaw-free low-temperature ceramic-forming insulated fire-resistant cables, securing a leading position in the domestic market and delivering substantial socio-economic benefits.
Behind this honor lies Zhongda Yuantong Cable’s long-term commitment to an innovation-driven strategy. Supported by the group company and its leadership, the firm has consistently prioritized technological advancement, providing solid backing for the project’s success. This award not only recognizes years of innovative efforts but also sets a benchmark for the transformation and upgrading of the cable industry, guiding it toward a new era of new quality productive forces.
Looking ahead, Zhongda Yuantong Cable will seize this achievement as a springboard to further increase R&D investment, accelerate the commercialization of scientific and technological results, and empower industry development with even more outstanding innovations. The company is committed to strengthening Zhejiang’s competitive edge in the cable industry, promoting deeper integration of innovation and industrial chains across China, fulfilling its responsibilities as a state-owned enterprise, advancing the high-quality development of new quality productive forces, and helping the cable industry of Zhejiang and beyond stand out in global competition to create a brighter future.
