At 9:00 am on May 28, 2025, the leaders of China National Nuclear Corporation (CNNC) and China Radio and Television Group visited TST cable to conduct research and guidance, and to gain an in-depth understanding of the research and development, production and industry application of high-temperature cables and sealing modules. Liang Gang, Wang Bo, An Donghui, Yan Huaicun, Wang Kaiyu and other senior executives of TST warmly received them, and the two sides conducted in-depth exchanges on the technological innovation of high-temperature cables and sealing modules and the coordinated development of the industry.
During the investigation, the leaders of China National Nuclear Corporation (CNNC) and China Radio and Television Group visited the company’s exhibition hall, intelligent production line and testing laboratory, focusing on the production process and performance testing of high-temperature resistant, corrosion-resistant and highly flexible cables. The technical team of TST cable introduced in detail the independently developed temperature-resistant -280℃~+500℃ series of cables, which are widely used in rail transit, medical, aerospace, nuclear power plants, hydropower plants, ships, new energy and other fields, and were highly praised by the visiting leaders.
During the visit, TST Cable focused on introducing nine series of products independently developed by the company, including special silicone rubber insulated cables, PI cables, fluoroplastic insulated cables and mineral insulated fireproof cables. These products have been widely used in key areas such as nuclear power plants, rail transit, and new energy vehicle battery systems.
A relevant person in charge of Shenzhen CNNC Group said: “From production equipment to process flow, TST Cable’s professionalism and refined management level are impressive, laying a solid foundation for subsequent cooperation.”
At the symposium, the two sides discussed the reliability of high-temperature cables in extreme environments, the trend of domestic substitution, and future cooperation directions. Shenzhen CNNC Group said that the excellent performance of TST cable’s high-temperature cable products in nuclear power projects was impressive, and it looked forward to deepening strategic cooperation; China Radio and Television Group proposed the intention of joint development in scenarios such as smart grids and base stations.
Summary of the leaders’ speeches:
The leaders of Shenzhen CNNC pointed out: “TST cable, a subsidiary of TESTECK, has an exciting accumulation of technology and localization capabilities in the field of high-temperature cables. In the future, it can further optimize the radiation resistance of cables in key parts of nuclear power plants and help national energy security.”
The executives of the Radio and Television Group emphasized: “High-temperature cables are one of the core materials for smart grid upgrades. We look forward to working with TST cable to promote the development of ‘base station dedicated cables’ technology and solve the problem of signal stability in high-temperature and high-humidity environments of base stations.”
The management of TST cable responded: “We will take this survey as an opportunity to increase R&D investment. We plan to launch nuclear power-specific cables with a radiation resistance level of ≥10^7 Gy within the year, and work with upstream and downstream companies to create an industry chain ecosystem for high-temperature cables and sealing modules.”
This survey not only demonstrates TST cable’s technical strength in the field of high-temperature cables, but also lays the foundation for cross-industry resource integration and market expansion. In the future, TST cable will continue to focus on technological innovation, work with partners to promote the upgrading of the high-end cable industry, and provide safer and more efficient solutions for major national projects and people’s livelihood.
