Overview
Copper braided strip is a versatile conductive component made by interlacing fine copper wires into a flat or tubular braid. It combines the high electrical conductivity of copper with exceptional flexibility, making it ideal for applications requiring movement or vibration resistance. The material is available in bare copper or tinned variants, with tinning offering enhanced corrosion protection. Its construction allows for efficient current carrying while accommodating thermal expansion and mechanical stress, distinguishing it from rigid busbars or solid conductors.
Structure and Working Principle
The braided structure consists of multiple copper wire strands woven in a crisscross pattern, creating a mesh-like configuration. This design provides inherent flexibility while maintaining electrical continuity across the entire length. When current flows through the braid, it distributes evenly across the parallel wire paths, reducing skin effect losses seen in solid conductors at high frequencies. The interstitial spaces between wires also facilitate heat dissipation and accommodate bending without significant resistance changes.
Key Features
Copper braided strips exhibit several notable characteristics: their conductivity typically reaches 95-100% IACS (International Annealed Copper Standard), ensuring minimal energy loss. The tinned versions provide oxidation resistance in humid or chemically aggressive environments. Flexibility metrics often exceed 10,000 bending cycles without failure, with temperature resistance ranging from -40°C to 150°C. The open braid structure allows for natural EMI/RFI shielding effectiveness while remaining lightweight compared to solid copper equivalents.
Application Areas
Primary applications include power substation grounding connections, where flexibility accommodates thermal expansion of busbars. They serve as jumpers in electric vehicle battery assemblies, allowing for vibration absorption between battery modules. In industrial settings, these strips create static discharge paths for rotating equipment. Telecommunications infrastructure utilizes them for tower grounding, while aerospace applications benefit from their weight savings and reliability in dynamic airframe components.
Maintenance and Precautions
Regular inspection should check for broken strands or discoloration indicating oxidation. In high-vibration environments, consider using strain relief fittings at termination points to prevent work hardening at connection interfaces. When installing, avoid sharp bends below the minimum bend radius (typically 5x strip width). For marine applications, specify tin-plated versions with additional protective coatings to resist saltwater corrosion. Periodic cleaning with electrical contact cleaner maintains optimal conductivity.
B2B Procurement Guide
Technical specifications should detail: strand count (typically 24-144 wires), wire diameter (0.05-0.2mm common), braid density (70-95% coverage), and plating thickness if tinned (2-5µm standard). Request mill certificates for copper purity verification (usually C11000 or C10100 grade). Lead times vary from stock items (1-2 weeks) to custom configurations (4-6 weeks). MOQs generally start at 100 meters for standard sizes. For large projects, inquire about reel packaging options to prevent kinking during transport. Sample testing should verify flexibility and conductivity under project-specific conditions.
