Description

Technical Field

[0001] This utility model relates to the field of copper conductor technology, specifically to a nickel-plated copper-based copper conductor. Background Technology

[0002] Copper conductors, as crucial carriers for power transmission and signal transmission in cables, are widely used in various fields. Traditional cables, however, suffer from poor corrosion resistance and high-temperature stability, making them prone to performance degradation and reduced service life in harsh environments such as marine, chemical, and high-temperature environments. Furthermore, the insulation, shielding, and sheathing layers of cables often fail to meet the demands of special scenarios in terms of weather resistance, interference resistance, and mechanical strength. This leads to problems such as short circuits, signal interference, and sheath damage in complex environments, limiting their application scope.

[0003] Although existing technologies have made some improvements to cable structures, problems such as insufficient bonding between structural layers and poor overall performance synergy still exist. Therefore, developing a cable with ultra-high performance nickel-plated copper-based conductors as its core, reasonable matching of structural layers, and excellent comprehensive performance is of significant practical importance.
