Wire And Cable Industry Technology Breakthroughs Lead Industrial Upgrading

New materials, new technology and intelligent application of full bloom

In 2025, China's wire and cable industry ushered in a series of major technological breakthroughs, these innovations not only improve product performance, but also promote the transformation of the entire industry to high-end, intelligent direction. According to industry conferences and authoritative reports show that the current technological breakthroughs are mainly concentrated in the application of new materials, new process innovation and the development of intelligent cables in three major areas.

In terms of materials, copper-aluminum alloy, carbon fiber composite conductor and other new conductor materials to gradually replace the traditional pure copper conductor, in reducing the weight by 30% while maintaining the same conductivity; high temperature polyimide, low-loss fluorine plastic and other high-performance insulation materials, so that the cable temperature resistance level to 250 ℃ or more, the transmission loss reduced by 15%. In terms of technology, 7+12 copper core synchronous stretching process, double-layer co-extrusion irradiation cross-linking technology and other innovative processes have significantly improved product performance. In terms of intelligence, the self-monitoring cable embedded with sensors realizes the leap from "physical connection" to "data node".

National Key Laboratory of High Efficiency Special Cable Technology
This laboratory is jointly built by Shanghai Cable Research Institute, Harbin Institute of Technology, Shanghai Jiao Tong University, and others, focusing on efficient transmission and conversion technology of electrical energy under large capacity, low loss, long-distance, and complex extreme conditions. The laboratory will be built as a source of independent innovation in special cable and key material technologies with international influence.

Shanghai Electric Cable Research Institute
As the only comprehensive wire and cable research institution in China, Shanghai Cable Research Institute provides full chain services from research and development to testing. Its subsidiary State Cable Testing Company is an authoritative testing institution in the industry, while Kaibo Cable Special Materials Company focuses on the research and production of special insulation and sheath materials.

Market Structure Changes
Technological breakthroughs are reshaping the wire and cable market landscape. Traditional power cables, construction cables still account for 60% of the market share but the growth rate slowed to less than 5%; specialty cables and smart cables accounted for 40%, the compound annual growth rate of more than 12%, becoming the core growth pole. It is expected that by 2030, the market share of high-end products will exceed 55%, the market size of 1 trillion yuan.

Expansion of application areas
New technology makes wire and cable from traditional power transmission to new energy, smart grid, industrial Internet and other scenarios of deep penetration. Offshore wind power with high-voltage submarine cable single transmission capacity exceeded 1,000 megawatts; flexible robotic cable bending life of 50 million times; new energy vehicles high-voltage cable can transmit more than 800V voltage.

Long-term development outlook
Industry experts pointed out that wire and cable technology will continue to break through along three directions: the material end to superconductivity, biodegradable bio-based materials; the process end to deepen the fusion of AI and intelligent manufacturing; and the system end to realize the multi-modal integration of power, data, and control. These innovations will support the extra-high voltage power grid, offshore wind power, data centers and other national strategic projects, to promote China's transformation from a "cable power" to a "cable power".
