Double shielding – Class A
Conventional coaxial cables (RG-6) Double shielding – Class A
Double-shielded Class A coaxial cable
With 2 shielding layers, these cables provide an outstanding shielding thanks to a high-coverage braid.
They belong in EN 50117 standard Class A, according to their structural properties:
- For 5 MHz - 30 MHz => TI < 5 mΩ/m
- For 5 MHz - 1000 MHz => SA > 85 dB
- For 1000 MHz - 2000 MHz => SA > 75 dB
- For 2000 MHz - 3000 MHz => SA > 65 dB
Where the transfer impedance (TI) defines how effective the shielding is at low frequencies, while the shielding attenuation (SA) defines it in the 30 MHz-to-3000 MHz range.
CPR Dca: Copper / copper
Dca Euroclass - Copper inner and outer conductors
- The copper inner conductor provides low electric resistance and an excellent response both for low and high frequencies
- The copper braid has a lower electric resistance and an outstanding shielding efficiency
- Dca Euroclass
CPR Eca: Copper clad aluminium /aluminium
Eca Euroclass - Copper-clad steel inner conductor and aluminium outer conductor
- The copper-clad steel inner conductor has a good mechanical behaviour
- The aluminium braid has a higher electric resistance and provides flexibility, improving malleability
- Eca Euroclass
