Custom Rectangular Copper Braided Wires from China Factory – Flexible, Conductive, and Reliable Suppliers
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 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, Perfect Fit for Your Needs
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.

Xingma Copper Industry can customize the cross-sectional area according to customer 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 by the customer.
Frequently Asked Questions
Q
What is the copper purity of the rectangular braided wire?
The rectangular braided wire is made from high-purity soft copper strands with a purity of ≥99.9%. This ensures excellent electrical conductivity, minimal transmission loss, and outstanding current-carrying capability.
Q
What is the difference between 8-spindle and 12-spindle braiding?
The 8-spindle braiding machine is suitable for standard precision applications such as small electronics and general electrical connections. The 12-spindle variant produces a denser and stronger braid, making it ideal for heavy-duty industrial applications that require higher mechanical strength and shielding performance.
Q
Can the cross-sectional area and wire diameter be customized?
Yes. Xingma Copper Industry offers full customization of the nominal cross-sectional area (mm²) and single wire diameter (ranging from 0.05 mm to 0.15 mm). Cutting lengths can also be specified based on customer drawings or technical requirements.
Q
What are the main advantages of a rectangular (flat) cross section over round wire?
The rectangular cross section increases the contact area by over 30% compared to round wires. This improves fit against flat terminals or equipment housings, simplifies installation, and distributes mechanical stress more evenly — resulting in enhanced long-term stability and reduced risk of deformation or strand breakage.
Q
In which industries or applications is this braided wire commonly used?
This product is widely used in electrical connections (power equipment grounding, new energy battery interconnects), EMI shielding for communication and high-frequency equipment, grounding systems for rail transport and industrial machinery, and anti-interference solutions for high-end electronic devices.
Q
Is the rectangular braided wire suitable for repeated bending environments?
Yes. The multi-strand fine copper construction is specifically designed to withstand repeated bending without fatigue. The uniform braiding tension and evenly distributed force across the flat cross section prevent localized stress concentration, ensuring long-term flexibility and durability in dynamic or vibration-prone environments.
