Flexible Rectangular Copper Busbar for High-Current Connections
Product Features
1. High Purity & Conductivity: Utilizes soft copper strands with ≥99.9% purity to maintain inherent high conductivity. This ensures low resistance, minimal transmission loss, and exceptional current-carrying capacity.
2.Precise & Robust Structure: Precision-braided on 8/12-carrier machines to form a uniform rectangular (flat wire) cross-section. This design ensures even stress distribution, eliminating the localized stress concentration typical of round wires, thereby preventing deformation or broken strands during long-term use.
3.Balanced Performance & Adaptability: Offers excellent flexibility (resistant to breakage under repeated bending), strong EMI shielding effectiveness, and reliable structural integrity. The adjustable braiding density allows customization to meet diverse strength and application requirements.
4.Flexible Customization: Fully customizable based on key parameters: nominal cross-sectional area, strand diameter (0.05mm-0.15mm), cut length (per drawing/customer specs), and carrier count (8/12 options), ensuring a perfect fit for specific application needs.
Application Fields
This product is extensively used in:
•Electrical connections (power equipment grounding, new energy battery interconnects)
•Electromagnetic shielding (communication/high-frequency equipment)
•Grounding systems (rail transit, industrial equipment safety grounding)
•High-end electronics requiring anti-interference protectionIt serves as a critical component for both conduction and shielding in complex environments.
Structural Composition
High-Purity Copper Strands: Soft copper strands with diameters from 0.05mm to 0.15mm and ≥99.9% purity form the conductive and structural base.
Multi-Carrier Braided Structure: Strands are interlaced via 8 or 12-carrier braiding machines. The 8-carrier configuration suits standard precision applications (e.g., compact electronics), while the 12-carrier option provides enhanced density and strength for heavy-duty industrial use. Uniform tension control prevents loosening or breakage.
Rectangular Cross-Section: Post-braiding shaping creates a uniform rectangular profile. Compared to round wires, this increases contact area by over 30% for better mating with flat terminals/ enclosures, simplifies installation, and improves long-term stability through optimized stress dispersion.
