Custom Rectangular Copper Braided Wires from China Suppliers | Factory Direct, 8/12 Spindles, Tailored Solutions
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, delivering long-term resistance to deformation and strand breakage.
🔄 Balanced Performance, Wide Adaptability
Combines high flexibility (multi-strand fine copper withstands repeated bending without fatigue), strong shielding effectiveness, and structural reliability (adjustable braid density to meet strength requirements across diverse applications).
🎯 Flexible Customization, Perfect Fit
Offers full parameter customization — nominal cross sectional area, single wire diameter (0.05 mm–0.15 mm), cut-to-length (per drawing or customer spec), and spindle count (selectable 8 or 12 spindles) — to perfectly match your specific scenario.
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. It serves as a core component for conduction and shielding in demanding environments.
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 and braiding, 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 8-spindle version suits standard precision uses (e.g., small electronics), while the 12-spindle variant increases density and strength for heavy-duty industrial applications. Uniform braiding tension prevents loosening or breakage.
3
Rectangular Cross Section (Flat Wire)
After braiding, a shaping process creates a regular rectangular profile. Compared with round wires, this design increases contact area by over 30%, improves fit against flat terminals or equipment housings, simplifies installation, and distributes mechanical stress for enhanced long-term stability.

Frequently Asked Questions
Q What is the copper purity of the rectangular braided wire?
The rectangular braided wire is crafted from high purity soft copper strands with a purity of ≥99.9%. This ensures excellent electrical conductivity, minimal impedance, and outstanding current carrying capability for demanding applications.
Q What is the difference between 8-spindle and 12-spindle braiding?
The 8-spindle braiding machine is suited for standard precision applications such as small electronics and general electrical connections. The 12-spindle variant produces a denser, stronger braid with higher density, making it ideal for heavy-duty industrial applications that require greater mechanical strength and shielding effectiveness.
Q Can the rectangular braided wire be customized to specific dimensions?
Yes. Xingma Copper Industry offers full parameter customization including nominal cross sectional area, single wire diameter (ranging from 0.05 mm to 0.15 mm), cut-to-length based on customer drawings or specifications, and spindle count selection (8 or 12 spindles). Please contact us with your requirements for a tailored solution.
Q What are the main advantages of a rectangular (flat) cross section over a round wire?
The rectangular cross section increases the contact area by over 30% compared to round wires. This improves the fit against flat terminals or equipment housings, simplifies installation, and distributes mechanical stress more evenly — resulting in enhanced long-term structural stability and reduced risk of deformation.
Q In which industries is the rectangular braided copper wire commonly used?
The wire is widely applied across multiple industries including power equipment grounding, new energy battery interconnects, EMI shielding for communication and high-frequency equipment, safe grounding in rail transport, industrial machinery, and anti-interference solutions for high-end electronic devices.
Q What nominal cross sectional area (CSA) options are available?
Standard available CSA options range from 0.55 mm² up to 25.00 mm², covering a wide variety of wire configurations with total wire counts from 280 up to 12,840. Custom cross sectional areas beyond the standard range can also be produced according to customer specifications.
