Custom Rectangular Copper Braided Wires from China Factory | Reliable Suppliers Offering 8/12 Spindle Solutions
Product Features
1. 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.
2. 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 the localized stress concentration common in round wires, delivering long term resistance to deformation and strand breakage.
3. 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).
4. Flexible Customization
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 (8 or 12 spindles).
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
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.
Multi Spindle Precision Braid
Strands are interlaced by 8 or 12 spindle braiders. The 8 spindle suits standard precision, while the 12 spindle increases density for heavy duty industrial use.
Rectangular Cross Section
Flat wire design increases contact area by over 30%, improves fit against terminals, and enhances mechanical stability.

Xingma Copper Industry can customize the square area according to customer requirements, with single wire diameters ranging from 0.05mm to 0.15mm. Rectangular braided wires are produced using 8-spindle or 12-spindle braiding machines. Cutting lengths are based on drawings or as specified by the customer.
FAQs
What is the purity of the copper used in your braided wires?
We use high-purity soft copper strands with a purity level of ≥99.9%, ensuring maximum conductivity and minimal signal loss.
Why is a rectangular (flat) cross-section better than a round one?
The rectangular design increases the contact surface area by over 30%, allowing for a better fit against flat terminals and improving mechanical stability and heat dissipation.
Can I customize the wire diameter and length?
Yes, we offer full customization. Single wire diameters range from 0.05mm to 0.15mm, and lengths can be cut precisely according to your technical drawings or specifications.
What is the difference between 8-spindle and 12-spindle braiding?
8-spindle braiding is ideal for standard precision applications like small electronics, while 12-spindle braiding provides higher density and strength for heavy-duty industrial grounding.
Is this product suitable for EMI shielding?
Absolutely. Our braided copper wire is widely used for EMI shielding in communication and high-frequency equipment to protect against interference.
Does the wire withstand repeated bending?
Yes, the multi-strand fine copper structure provides high flexibility, allowing it to withstand repeated bending without fatigue or strand breakage.
