Advantages
High Conductivity: Made of Cu-ETP C11000 pure copper, ensuring minimum voltage drop and heat generation.
Excellent Flexibility: Braided structure allows easy bending in tight spaces, suitable for dynamic bending and vibration environments, reducing stress of rigid connections.
Corrosion Resistance Options: Bare copper for general use; tin-plated copper braided mesh resists moisture, salt spray and mild chemical attack, ideal for outdoor or industrial polluted areas.
EMI Shielding Performance: Provides excellent electromagnetic shielding effectiveness (SE) for cable shield grounding, cabinet shielding, etc.
Wide Specification Range: Widths from 25mm to 100mm, single wire diameters 0.10/0.12mm, 1~4 parallel strands, can be combined for larger cross sections.
Operating Conditions
Temperature Range: Bare copper -40°C to +150°C (continuous); tin-plated copper -40°C to +150°C, short-term up to +180°C.
Environmental Suitability: Bare copper avoids long-term exposure to high concentration sulfides or acidic environments; tin-plated copper can be used in humid, salt spray and mild acid/alkali conditions.
Installation Requirements: Bending radius recommended ≥5 times total thickness of the mesh; use copper or tin-plated copper crimp terminals when connecting to busbars or terminals.
Current Rating: Depends on cross-sectional area and heat dissipation; typically used for grounding, equipotential bonding and auxiliary current-carrying circuits.
Maintenance
Regular Inspection: Every 6 months check for broken strands, discoloration (heavy oxidation) or mechanical damage. For tin-plated products, check for peeling of the coating.
Cleaning Method: Use dry compressed air or a soft brush to remove dust; for oil contamination, wipe with anhydrous alcohol or a mild detergent and then dry thoroughly. Do not use acidic or alkaline cleaners.
Avoid Overstretching: Avoid axial tension during installation; keep natural state to prevent change in mesh density and conductive cross-section.
Service Life
Under normal indoor conditions (temperature -40°C to +120°C, dry and non-corrosive atmosphere), the designed service life of copper braided mesh is 15-20 years.
Tin-plated copper braided mesh can achieve 10-15 years in humid or mildly corrosive environments.
Thanks to pure copper material and flexible braided structure, it can achieve a service life comparable to the main equipment in static grounding applications.

Frequently Asked Questions (FAQ)
Copper braided mesh is widely utilized for electrical grounding, equipotential bonding, flexible conductive connections, and EMI/RFI shielding across industrial power cabinets, transformers, and electronic systems.
Tin-plated copper is recommended for humid, outdoor, marine, or chemically corrosive environments as the tin layer provides superior anti-oxidation and corrosion resistance compared to bare copper.
Yes. We provide complete customization options including widths from 25mm to 100mm, wire diameters of 0.10mm or 0.12mm, and multiple parallel strand counts to meet specific electrical conductivity and space requirements.
During installation, maintain a bending radius of at least 5 times the total thickness, avoid axial overstretching to preserve mesh density, and use proper crimp terminals when terminating to busbars.
We supply copper braided mesh in continuous rolls, sturdy plastic spools, or heavy-duty wooden drums depending on the product width, total length, and customer handling preferences.
