Custom Copper Braided Wires from China Suppliers: 8/12 Spindles, Tailored by Factory for Optimal Conductivity
Product Features
-
1Pure Material, Excellent ConductivityCrafted 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.
-
2Precision Braiding, Stable StructureWoven 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.
-
3Balanced Performance, Wide AdaptabilityCombines 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).
-
4Flexible Customization, Perfect Fit for Your NeedsOffers 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 StrandsSelected 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 StructureStrands 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.

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 square 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
What is the copper purity of the rectangular braided wire, and why does it matter?
The rectangular braided wire uses soft copper strands with a purity of ≥99.9%. Higher purity copper provides lower electrical resistance, better conductivity, and superior current-carrying capacity, which is critical for power equipment grounding, battery interconnects, and EMI shielding applications.
What is the difference between 8-spindle and 12-spindle braiding machines?
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, stronger braid with higher mechanical strength, making it ideal for heavy-duty industrial environments and larger cross-sectional areas (e.g., 25 mm²).
Can the cross-sectional area and wire diameter be customized?
Yes. Xingma Copper Industry offers full customization of nominal cross-sectional area (from 0.55 mm² to 25 mm² and beyond), single wire diameter (0.05 mm–0.15 mm), spindle count (8 or 12 spindles), and cutting length based on customer drawings or specifications.
What are the main advantages of a rectangular (flat) cross section compared to 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, distributes mechanical stress more evenly, and enhances long-term structural stability and electrical performance.
In which industries and applications is this rectangular braided wire commonly used?
It is widely used in electrical connections (power equipment grounding, new energy vehicle battery interconnects), EMI shielding (communication and high-frequency equipment), grounding systems (rail transport and industrial machinery), and anti-interference solutions for high-end electronic devices.
How does the multi-strand fine copper structure improve flexibility and durability?
The multi-strand construction distributes bending stress across hundreds or thousands of individual fine copper strands, allowing the wire to withstand repeated flexing without fatigue or strand breakage. This makes it far more durable than solid or fewer-strand conductors in dynamic or vibration-prone environments.
