Product Description

Product Features
Pure Material, Excellent Conductivity
Crafted from high purity soft copper strands (≥99.9% purity), preserving copper's inherent high conductivity. Ensures low impedance transmission with minimal loss and outstanding current carrying capability.
Precision Braiding, Stable Structure
Woven on 8-spindle or 12-spindle braiding machines into a uniform rectangular (flat) cross section. Force is evenly distributed, eliminating localized stress concentration common in round wires.
Balanced Performance, Wide Adaptability
Combines high flexibility (multi-strand fine copper withstands repeated bending), strong shielding effectiveness, and structural reliability across diverse applications.
Flexible Customization
Offers full parameter customization: nominal cross-sectional area, single wire diameter (0.05 mm–0.15 mm), cut-to-length, and spindle count (8 or 12 spindles) to match your needs.
Application Fields
Widely used in electrical connections (e.g., power equipment grounding, new energy battery interconnects), EMI shielding (communication/high-frequency equipment interference protection), grounding systems (safe grounding for rail transport and industrial machinery), and anti-interference solutions for high-end electronic devices.

Structural Composition
1
High Purity Copper Strands

Selected soft copper strands of 0.05 mm–0.15 mm diameter (≥99.9% purity) form the foundation for conductivity, guaranteeing excellent electrical performance.

2
Multi-Spindle Precision Braid Structure

Strands are interlaced by 8 or 12-spindle braiders into a tight rectangular mesh. The 12-spindle variant increases density and strength for heavy-duty industrial applications.

3
Rectangular Cross Section (Flat Wire)

After braiding, a shaping process creates a flat profile. This design increases contact area by over 30%, improves fit against terminals, and simplifies installation.

The manufacturer can customize the cross-sectional area according to requirements, with single wire diameters ranging from 0.05 mm to 0.15 mm. Rectangular braided wires are produced using 8-spindle or 12-spindle braiding machines. Cutting lengths are based on drawings or as specified.
Frequently Asked Questions
Q What is the copper purity of the rectangular braided wire?
The wire is made from high-purity soft copper strands with a purity of ≥99.9%. This ensures excellent electrical conductivity and minimal transmission loss.
Q What is the difference between 8-spindle and 12-spindle braiding?
The 8-spindle machine is for standard precision like small electronics. The 12-spindle variant produces a denser braid for heavy-duty industrial applications requiring higher mechanical strength.
Q Can the cross-sectional area and wire diameter be customized?
Yes. Full customization is available for the nominal cross-sectional area and single wire diameter (0.05 mm to 0.15 mm). Cutting lengths can also be specified.
Q What are the advantages of a flat cross section over round wire?
The rectangular cross section increases contact area by over 30%, improves fit against terminals, simplifies installation, and distributes mechanical stress more evenly.
Q In which industries is this braided wire commonly used?
It is widely used in power equipment grounding, new energy battery interconnects, EMI shielding, and anti-interference solutions for high-end electronics.
Q Is it suitable for repeated bending environments?
Yes. The multi-strand fine copper construction is designed to withstand repeated bending without fatigue, ensuring durability in dynamic or vibration-prone environments.
