Zhejiang Yuantong Wire & Cable Manufacturing Co.,Ltd. Wins Second Prize at Zhejiang Provincial Science and Technology Progress Awards for Breakthrough in Fire-Resistant Cable Technology

On November 22, 2024, at the Mobilization and Deployment Conference for Accelerating the Construction of an Innovative Zhejiang and Developing New Quality Productive Forces Based on Local Strengths, as well as the Zhejiang Provincial Science and Technology Awards Conference held in Hangzhou, the project jointly declared by Zhejiang Yuantong Wire & Cable Manufacturing Co.,Ltd. and Zhejiang Zhongda Yuantong Special Cable Co.,Ltd., titled “Key Technologies and Industrialization of Efficient Manufacturing for Low-Temperature Ceramicizing Insulation Fire-Resistant Cables”, was awarded the Second Prize of Zhejiang Provincial Scientific and Technological Progress Award.

The project emerged as one of the highlights of the conference, showcasing the strong technological capabilities and innovation leadership of Wuchan Zhongda Group’s cable division.

This award-winning project represents a major breakthrough in fire-resistant cable manufacturing. It successfully developed a unique process for low-temperature rapid ceramicization, enabling flexible cables to maintain fire resistance at 750°C. A specially designed vertical magnesium oxide filling system was also developed, making the large-scale production of kilometer-grade rigid fire-resistant cables possible for the first time in China. The project’s technological indicators have reached internationally advanced levels, filling key gaps in the domestic market.

To date, the project has obtained multiple domestic and international patents, including one U.S. invention patent, one German utility model patent, six Chinese invention patents, and ten utility model patents, as well as two academic publications. On the industrial side, the project has significantly boosted production efficiency—achieving a 99-fold increase, reducing costs by 15%, and reaching a 99.5% product qualification rate. It is the first time that defect-free, low-temperature ceramicized fire-resistant cables have been mass-produced globally, giving the company a leading position in China’s market and delivering considerable economic and social value.

This achievement reflects the long-term commitment of Zhejiang Yuantong Wire & Cable Manufacturing Co.,Ltd. to innovation-driven growth. The company, under the guidance of Wuchan Zhongda Group, places great emphasis on R&D and continuous technological advancement. This award not only recognizes years of innovative practice but also sets a benchmark for transformation and upgrading across the entire wire and cable industry in China.

Looking ahead, Zhejiang Yuantong Wire & Cable Manufacturing Co.,Ltd. will take this recognition as a catalyst to further invest in research and development, accelerate the transformation of technological outcomes, and continue empowering the industry with cutting-edge innovations. The company will deepen integration between innovation and industrial chains, shoulder its responsibilities as a state-owned enterprise, and contribute to the high-quality development of new productive forces in Zhejiang and across the nation—ensuring that China's cable industry thrives in global competition.
