Product Overview

Tinned - Copper Braided Wire is a flexible braided conductor made from multiple strands of tinned copper wire. It features excellent conductivity and shielding performance, suitable for scenarios such as grounding, Electromagnetic Interference (EMI) shielding, and power distribution. It is widely used in automotive and industrial equipment.


Product Features and Advantages

(1) Outstanding Flexibility

Performs excellently in dynamic and vibration - prone environments. It is not easy to break due to deformation during installation and use, and can adapt to complex installation spaces.

(2) High Conductivity

Maintains low resistance in power and grounding systems, ensuring efficient power transmission and reducing energy loss.

(3) Corrosion Resistance

The tin - plating layer enhances durability, resisting moisture, chemical corrosion, etc., prolonging the product service life and reducing maintenance costs.

(4) EMI Shielding

Effectively reduces electromagnetic interference, protects the signal stability of electronic devices, and is suitable for scenarios with high requirements for the electromagnetic environment.

(5) Easy Termination

Compatible with soldering and crimping processes, simplifying the installation process and improving production efficiency.


Application 

Grounding straps : used in electrical panels, switchgear, distribution boards, and transformers


EMI shielding : acts as a conductive screen around cables, absorbing and redirecting unwanted signals.

                      widely used in data transmission cables, instrumentation wiring, and aerospace/military systems.


Power distribution : applied in battery banks, UPS systems, EV battery packs, and high-current busbar connections


Cable shielding : used in control cables, robotics cables, and industrial automation.


Automotive Industry: used in wiring harnesses, EV charging systems, as bonding straps between vehicle chassis

                              and electronic modules


Railway & Aerospace: aircraft use braided straps for grounding and lightning protection





Competitive Advantages vs. Competitors

(1) Performance Aspect

Compared with some competitors, this product achieves a better balance between flexibility and conductivity. Competitors may lack sufficient flexibility and be easily damaged in vibration environments; or they may sacrifice conductivity to pursue flexibility, affecting power transmission efficiency.

(2) Corrosion Resistance Aspect

With proper tin - plating process and quality control, its corrosion resistance is better than that of some competitors. There is no easy occurrence of plating layer peeling and conductor corrosion during long - term use, ensuring the stable operation of the system.

(3) Customization Aspect

Provides comprehensive OEM/ODM support. It can be customized for plating thickness, strand construction, resistance and tensile targets, insulation and shielding options to meet diverse needs. Most competitors can only provide standard products, with poor flexibility.
