Shielding Braids
Yeshwant Wires is a leading Shielding Braids manufacturer in India, delivering premium-quality copper braids that provide reliable electromagnetic interference (EMI) and radio frequency interference (RFI) protection for electrical and electronic systems. Our shielding braids are engineered to offer exceptional flexibility, high conductivity, and durable mechanical strength. Manufactured from 99.99% electrolytic grade copper, these braids ensure superior conductivity while providing effective shielding.
Available in bare, tinned, or silver-plated finishes with customizable diameters and braid densities, these braids deliver exceptional EMI/RFI protection, flexibility, corrosion resistance, and durability. They comply with IS 8130, IEC 60228, and ASTM B3 standards and are ideal for power cables, control cables, communication lines, transformers, switchgear, and industrial equipment.
Description
Shielding Braids are woven or braided copper conductors applied around cables or assemblies to prevent electromagnetic and radio frequency interference from affecting signal transmission. The flexible construction allows the braids to conform easily to cable shapes while providing robust EMI/RFI protection, reducing electrical interference and minimizing energy losses.
These braids are extensively used in power distribution, control systems, communication networks, electronic devices, transformers, switchgear panels, industrial machinery, automotive electronics, and renewable energy systems where signal integrity and safety are paramount for operational excellence and reliable performance in demanding applications.

Technical Specifications
| Property | Specification | Significance |
|---|---|---|
| Material | Bare or Tinned Copper, Nickel-Plated Copper, Aluminum, or Stainless Steel. | The choice of material affects performance: Copper provides excellent conductivity (low-frequency magnetic shielding). Tinning/Nickel-plating is used for corrosion resistance and enhanced high-frequency attenuation. |
| Construction Type | Fine strands woven into a flexible, tubular structure (braid) designed to slip over an insulated cable core or bundle. | The tubular shape allows for easy application and provides 360-degree coverage. The fine strands ensure high flexibility while maintaining coverage integrity during bending. |
| Optical Coverage (%) | Typically specified between 85% and 98% (e.g., 90% nominal). | This is the percentage of the cable's surface covered by the braid. Higher coverage correlates to better Shielding Effectiveness (SE), especially against high-frequency (EMI/RFI) noise. |
| Shielding Effectiveness (SE) | Measured in Decibels (dB), often ranging from 50 dB to 100+ dB across a broad frequency spectrum. | The primary measure of performance. A higher dB rating means the shield is more effective at blocking electromagnetic interference (EMI) both entering (immunity) and leaving (emissions) the cable. |
| Flexibility | High, due to the woven construction and fine strands. | Essential for applications like dynamic industrial robotics, moving machine parts, and military/aerospace cables where the assembly must flex continuously without fracturing the shielding layer. |
| Termination Method | Often terminated using a 360° crimp, a braid clamp, or soldered directly to the connector shell (backshell). | Proper low-impedance termination is critical; the shield is useless if its connection to the ground reference is compromised. It must be continuous and low-resistance. |
| Key Function | Electromagnetic Compatibility (EMC) protection: Reducing both emitted noise (EMI) and susceptibility to external noise (RFI). | Used in data, instrumentation, control, and sensitive power cables to maintain signal integrity in electrically noisy environments. |
| Applicable Standards | Military (e.g., MIL-C-24640), Aerospace (e.g., AS22759), and general EMC standards (e.g., relevant parts of IEC 61000). | Compliance ensures the braid and the resulting cable assembly meet rigorous performance and environmental requirements for shielding and durability. |
Applications
