Product Description

Product Features

⚡

High Purity & Conductivity Utilizes soft copper strands with ≥99.9% purity to maintain inherent high conductivity. This ensures low resistance, minimal transmission loss, and exceptional current-carrying capacity.

⚙️

Precise & Robust Structure Precision-braided on 8/12-carrier machines to form a uniform rectangular (flat wire) cross-section. This design ensures even stress distribution, eliminating the localized stress concentration typical of round wires.

🛡️

Balanced Performance & Adaptability Offers excellent flexibility (resistant to breakage under repeated bending), strong EMI shielding effectiveness, and reliable structural integrity.

🛠️

Flexible Customization Fully customizable based on key parameters: nominal cross-sectional area, strand diameter (0.05mm–0.15mm), cut length, and carrier count (8/12 options).

Application Fields

🔌

Electrical connections — power equipment grounding, new energy battery interconnects

📡

Electromagnetic shielding — communication & high-frequency equipment

🚆

Grounding systems — rail transit, industrial equipment safety grounding

💻

High-end electronics requiring anti-interference protection

Structural Composition

High-Purity Copper Strands: Soft copper strands with diameters from 0.05mm to 0.15mm and ≥99.9% purity form the conductive and structural base.
Multi-Carrier Braided Structure: Strands are interlaced via 8 or 12-carrier braiding machines. 8-carrier configuration suits standard precision, while 12-carrier provides enhanced density and strength.
Rectangular Cross-Section: Post-braiding shaping creates a uniform rectangular profile, increasing contact area by over 30% for better mating with flat terminals.

The square area can be customized according to 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.

Frequently Asked Questions

What copper purity is used in these rectangular braided wires?

The rectangular braided wires use soft copper strands with a purity of ≥99.9%. This high purity ensures excellent electrical conductivity, low resistance, and superior current-carrying capacity.

What strand diameters are available for customization?

Individual wire diameters range from 0.05mm to 0.15mm. The nominal cross-sectional area, carrier count (8 or 12 spindles), and cut length can all be customized based on specifications.

What is the difference between 8-carrier and 12-carrier braiding configurations?

The 8-carrier configuration is suited for standard precision applications like compact electronics, while the 12-carrier option provides enhanced density and mechanical strength for heavy-duty industrial use.

Why is a rectangular cross-section preferred over a round wire design?

The rectangular cross-section increases the contact area by over 30%, enabling better mating with flat terminals. It also simplifies installation and ensures even stress distribution to prevent deformation.

What industries and applications are these braided wires suitable for?

These wires are widely used in power equipment grounding, new energy battery interconnects, electromagnetic shielding for communication equipment, and industrial safety grounding systems.

Can the cutting length be customized to specific requirements?

Yes. Cutting lengths are fully customizable based on customer-provided drawings or specifications to meet diverse project requirements across different industries.
