At 9:00 am on July 25, 2025, the experts and leaders of China CRRC Group visited Shenzhen TST cable company to conduct special audit guidance on the research and development, production and quality management system of high-temperature cables. Liang Gang, general manager of TST cable company, led the senior management and technical team to warmly welcome them and fully demonstrated the company’s technical strength and compliance management results in the field of high temperature cables.
At the symposium, the general manager of TST cable introduced the company’s development history and core advantages to the CRRC experts in detail. As an enterprise focusing on the research and development and manufacturing of high-temperature cables, TST cable company has independently developed high-temperature resistant cable technology, and its products are widely used in rail transportation, energy equipment and other fields. The company has obtained a number of national patents. Its “heat-resistant cable for use in high-temperature environments” has been authorized by the State Intellectual Property Office. It adopts a glass fiber layer, a polytetrafluoroethylene layer and a silicone rubber composite structure. It has excellent heat insulation, wear resistance and aging resistance, and can meet the needs of extreme working conditions.
CRRC experts highly recognize TST cable company’s technical reserves and compliance management capabilities. The expert group of 4 people inspected the production line on site, focusing on the raw material testing, process standardization and quality traceability system, fully affirmed the company’s strict control in the production process, and put forward constructive suggestions on intelligent upgrading, green manufacturing and other directions. CRRC experts said: “TST cable is driven by innovation and has advanced technology routes. It has great potential for cooperation with CRRC in the fields of high-speed rail and maglev.”
This CRRC on-site audit is not only a comprehensive test of TST cable’s comprehensive strength, but also marks a new stage in the cooperation between the two parties. In the future, TST cable will continue to deepen its technical collaboration with CRRC, relying on its independent innovation capabilities and compliance management system to provide safer and more efficient cable solutions for high-end equipment such as rail transit, and help the high-quality development of global intelligent manufacturing.
