FAQ
Q: What is a copper braid shielded cable?
A: A copper braid shielded cable features a woven copper mesh layer around conductors to block electromagnetic interference (EMI) and radio frequency interference (RFI).
Q: Why is copper braid shielding preferred over foil shielding?
A: Copper braid offers higher flexibility, better mechanical durability, and superior grounding performance compared to aluminum foil.
Q: In which industries are copper braid shielded cables essential?
A: Critical in industrial automation, medical equipment, aerospace, and high-speed data transmission systems where EMI protection is vital.
Q:What standards govern copper braid shielded cables?
A:Compliant with EN 50525 (Europe), UL 2250 (North America), and IEC 60502 (international).
Q: How does copper braid shielding improve signal integrity?
A: It minimizes noise distortion by absorbing and redirecting external electromagnetic waves, ensuring clean signal transmission.
Q: What’s the temperature rating of copper braid shielded cables?
A: Typically rated for -40°C to +90°C (Europe) or -40°C to +75°C (UL standards).
Q: Can copper braid shielded cables be used in wet environments?
A: Yes, with proper insulation (e.g., PVC or LSZH jackets) to resist moisture and chemicals.
Q: How is shielding effectiveness measured?
A: Attenuation (dB) is tested per EN 50288 or MIL-STD-220A, with 70-90dB common for industrial cables.
Q: Are copper braid cables suitable for high-frequency applications?
A: Yes, their low resistance and high conductivity make them ideal for RF, Ethernet, and telecom signals up to 10 GHz.
