Breakthrough Achievement in Cable Innovation
On March 3, 2025, JinChuan Copper and Precious Metals Wire and Cable Company, a wholly-owned subsidiary of JinChuan Group Co., Ltd., marked a significant achievement in the wire and cable industry. The company’s independently developed 35kV and below cross-linked polyethylene insulated cold-resistant power cables passed the rigorous "Type Test at -55°C Low Temperature" conducted by TICW. This breakthrough highlights JinChuan’s expertise in creating durable, high-performance cables capable of withstanding extreme environmental conditions, paving the way for enhanced power infrastructure in cold regions worldwide.
Addressing Cold-Climate Challenges
As a leader in China’s wire and cable sector, JinChuan has long prioritized technological innovation to meet the evolving demands of the global energy market. With rising energy needs, cables must deliver not only high conductivity but also exceptional weather resistance and reliability. In cold climates, traditional cables often face challenges: low temperatures can make insulation materials stiff and brittle, leading to cracking, fracturing, and compromised performance. These issues threaten the safety and stability of power transmission, particularly in regions like northern China, Russia, or the Arctic.
R&D Triumphs with Advanced Design
To address this, JinChuan assembled a dedicated R&D team to tackle the technical hurdles of cold-resistant cable design. Through extensive research into material selection, structural optimization, and advanced manufacturing processes, the team developed a game-changing solution. The new cables feature specially formulated insulation and sheath materials that retain flexibility and mechanical strength even at -55°C. Coupled with an optimized structural design, these cables ensure stability and durability in the harshest low-temperature environments.
Rigorous Testing Confirms Superior Quality
JinChuan’s commitment to quality is evident in its testing process. The cables underwent stringent low-temperature impact and tensile tests, adhering to national standards and industry regulations. The results exceeded expectations, confirming the cables’ ability to perform reliably under extreme conditions. This success builds on JinChuan’s existing technical strengths, such as its use of high-purity copper cathodes produced in-house and advanced equipment from global leaders like Southwire (USA) and Niehoff (Germany).
Powering Infrastructure in Frigid Regions
The implications of this innovation are far-reaching. These cold-resistant power cables provide a robust solution for power infrastructure projects in frigid climates, supporting industries, communities, and critical facilities like hospitals and metro systems. As the largest producer of copper rod, cables, and wires in western China, JinChuan is well-positioned to meet growing demand in domestic and international markets.
Innovation Fuels Ambitious Growth
This milestone is a testament to JinChuan’s broader mission, rooted in the directives of President Xi Jinping during his visit to the parent company. Emphasizing innovation-driven development, JinChuan continues to invest heavily in R&D to enhance its technological capabilities and market competitiveness. With annual sales revenue exceeding 20 billion RMB and a goal to surpass 1 trillion RMB by 2030, the company is driving high-quality development while solidifying its status as a global leader in non-ferrous metal processing and advanced materials.
Future Plans for Cable Excellence
Looking ahead, JinChuan Copper and Precious Metals Wire and Cable Company plans to further refine its cold-resistant cable technology, expanding its applications and improving performance. This breakthrough not only showcases the company’s engineering prowess but also reinforces JinChuan Group’s legacy of excellence in the wire and cable industry.
