43mm Copper Foil Wire Braided Mesh Tube

When selecting shielding solutions for complex electronic systems, the choice of braided mesh tube diameter directly affects installation ease and performance. Our copper foil wire braided mesh tubes are engineered for reliable EMI protection across a range of cable diameters. For applications that demand a slightly smaller internal clearance, the 41mm Copper Foil Wire Braided Mesh Tube provides a firm grip on compact harnesses. Moving up incrementally, the 42mm Copper Foil Wire Braided Mesh Tube suits mid-range bundling without adding bulk. When the cable assembly expands beyond standard dimensions, stepping to the 44mm Copper Foil Wire Braided Mesh Tube or the 45mm Copper Foil Wire Braided Mesh Tube accommodates thicker looms commonly found in power distribution and industrial machinery. Each variant is woven from high-purity copper foil strips and tinned copper wire to form a flexible, conductive jacket. The braided construction ensures low-resistance contact across the entire surface, effectively suppressing radiated emissions from several kHz up to GHz frequencies. The open weave also promotes heat dissipation and allows visual inspection of underlying cables. These tubes resist oxidation and maintain spring-like recovery after repeated flexing, making them suitable for robotics, protective conduits, and expansion joints. Their seamless integration with standard grounding clamps and connectors simplifies retrofitting into existing enclosures. Typical uses include shielding for data transmission lines, dynamic grounding straps, and vibration damping in automotive sensor harnesses. The combination of lightweight design and high tensile strength reduces strain on connectors while preserving signal integrity.

The 43mm Copper Foil Wire Braided Mesh Tube occupies a versatile middle ground, offering ample room for cable bundles common in power inverters, EV charging harnesses, and server rack interconnects. This specific diameter balances compactness with generous internal volume, allowing it to slide over irregularly shaped connectors without excessive snagging. Its weave density is optimized to deliver over 75 dB of shielding attenuation at 100 MHz, while still maintaining a flexural modulus that eases installation around corners. Below is a detailed breakdown of its key specifications.

Installation of the 43mm Copper Foil Wire Braided Mesh Tube is straightforward: the braid expands slightly when compressed longitudinally and contracts when pulled, allowing easy routing over connectors. Its cut ends can be terminated with standard copper ferrules or crimp sleeves to prevent fraying. The tube’s high coverage factor—typically above 92%—minimizes leakage gaps while preserving enough openness for air circulation. Field technicians appreciate the balance between stiffness and pliability, which holds the tube in place after forming but permits hand bending without tools. For systems where multiple diameter transitions are necessary, the 43mm version serves as an intermediate sleeve that can be mated with smaller or larger diameters using conductive tape or clamp adapters. Its consistent wall thickness and roundness contribute to repeatable impedance paths in ground-loop applications. This product is fully compliant with RoHS and REACH directives, and material certificates are available upon request. Stocks are maintained in North American and European warehouses, enabling next-day dispatch for most standard roll lengths.
