1. Conductivity Efficiency
Under the same cross-sectional area, high-quality copper braided wire offers conductivity comparable to solid copper busbars. The key determinant of conductivity lies in the purity of the copper material, not its external form. When the copper content reaches 99.95% or higher, the multi-strand fine wire braided structure not only does not reduce conductivity efficiency but, due to its larger surface area, better addresses the skin effect in high-frequency applications.
Reasonable braiding techniques ensure the stability of the current path. The diameter selection of individual copper wires is crucial: overly thin wires increase interfacial resistance, while overly thick wires can compromise flexibility. High-quality braided wires use precise copper wire ratios to maintain flexibility while ensuring conductivity efficiency.
2. Surface Treatment Process
While tin plating enhances oxidation resistance, it does introduce additional resistance. However, with precisely controlled plating thickness, this impact can be minimized. In dry indoor environments, bare copper braided wire is indeed a superior conductive choice. In humid or corrosive environments, moderate tin plating protection ensures long-term stable conductive performance.
3. Installation Method
Excessive bending alters the contact state between copper wires, increasing localized resistance. The correct approach is to adhere to the minimum bending radius requirements and use suitable terminals for crimping. Additionally, regularly inspect the tightness of connection points to prevent increased contact resistance due to loosening. The conductive performance of copper braided wire is influenced by factors such as material purity, structural design, surface treatment, and installation maintenance. Through scientific selection and standardized installation, copper braided wire not only meets conductivity requirements but also provides more reliable electrical connection solutions under complex working conditions. It is recommended that users, under professional guidance, make the most suitable choices based on specific application scenarios.
