The independently developed 35kV and below cross-linked polyethylene insulated cold-resistant power cables by Jinchuan Copper and Precious Metals Wire and Cable Company have successfully passed the "Type Test at -55°C Low Temperature" conducted by TICW. This milestone signifies a breakthrough for Jinchuan Cable in terms of extreme environmental resistance, providing solid technical support for the construction of power infrastructure in cold regions.
As a leader in the domestic wire and cable industry, Jinchuan Cable has always been committed to technological innovation and product development. With the continuous growth in global energy demand, higher requirements have been placed on the weather resistance and reliability of wire and cable products. In cold regions, low temperatures can cause cable materials to become stiff and brittle, leading to a decline in insulation performance and potential issues such as cracking and fracturing, significantly impacting the safety and stability of power transmission.
Jinchuan's power cables
To tackle this technical challenge, Jinchuan Copper and Precious Metals Wire and Cable Company assembled a research and development team to conduct in-depth research on material selection, structural design, and manufacturing processes for cold-resistant cables. After numerous tests and improvements, they successfully developed power cables with excellent low-temperature resistance.
These power cables utilize specially formulated insulation and sheath materials that maintain good flexibility and mechanical strength even at extremely low temperatures. In addition, the cable's structural design has been optimized to ensure stability and durability in low-temperature environments. To validate the actual performance of the cables, Jinchuan has conducted rigorous low-temperature impact and tensile tests on finished products in accordance with national standards and industry regulations, all of which met the expected targets.
The successful completion of these two tests not only confirms the outstanding performance of Jinchuan's cold-resistant power cables but also showcases the strong technological innovation and product development capabilities of Jinchuan Copper and Precious Metals Wire and Cable Company. The company will continue to increase investment in research and development, improve its technological capabilities and market competitiveness, and drive high-quality development.
