46mm Copper Foil Wire Braided Mesh Tube
Introducing the premium 46mm Copper Foil Wire Braided Mesh Tube, an ideal solution for electromagnetic interference (EMI) shielding, grounding, and cable protection. Built from high-purity copper foil wires tightly braided into a flexible mesh, this tube delivers superior conductivity and durability. Alongside its popular counterparts, including the 41mm Copper Foil Wire Braided Mesh Tube, 42mm Copper Foil Wire Braided Mesh Tube, 43mm Copper Foil Wire Braided Mesh Tube, and 44mm Copper Foil Wire Braided Mesh Tube, the 46mm variant offers a larger diameter to accommodate thicker cable bundles while maintaining exceptional shielding effectiveness. Engineered for industries such as telecommunications, automotive, aerospace, and power generation, the mesh tube withstands harsh environmental conditions, resists oxidation, and provides low-resistance electrical paths. Its braided structure allows for easy expansion and installation over connectors, making it a versatile choice for retrofitting and new installations alike. The braided tube achieves shielding effectiveness levels exceeding 60 dB at frequencies from 30 MHz to 1 GHz when measured per IEEE 299, and its continuous operating temperature spans cryogenic conditions up to 200°C, meeting MIL-SPEC and IPC/EIA J-STD requirements for solderability and reliability.
The 46mm Copper Foil Wire Braided Mesh Tube is engineered to exceed industry benchmarks for shielding performance and mechanical resilience. When installed as a ground strap, it offers a low-inductance path that effectively suppresses high-frequency noise. Users appreciate the convenience of its tubular shape, which slides effortlessly over cable assemblies and can be secured with simple metal clamps or soldered directly to connector backshells. Because the mesh retains its shape after bending, it is easy to route through tight spaces—a frequent challenge in avionics bays or server racks. The product can be easily cut to length and shaped to fit irregular harnesses, simplifying assembly in complex electrical systems. Below are the key features that distinguish this product:

Its open-weave design promotes heat dissipation and allows visual inspection without disassembly, saving maintenance time. Custom configurations, including tin-plated or nickel-plated options, can be supplied to match specific environmental or conductivity requirements. Quality assurance includes dimensional checks with laser micrometers, surface resistance measurements, and salt-spray testing per ASTM B117. Each coil is labeled with part number, lot number, and date code for full traceability. Tin plating enhances solderability and reduces oxide formation, while lightweight tin-plated copper-clad aluminum variants are available for weight-sensitive applications. The mesh tube ships on spools or industrial reels with moisture-resistant packaging, ensuring it arrives in optimal condition for immediate integration.
