Extension cords With triple shielding cable
Class A++ Trishield (TSH) coaxial cable
With three shielding layers (Trishield), this cables provide the highest immunity to interference thanks to its very high shielding. Recommended in cases of high electromagnetic noise levels.
They belong in EN 50117 standard Class A++, according to their structural properties:
- For 5 MHz - 30 MHz => TI < 0.9 mΩ/m
- For 30 MHz - 1000 MHz => SA > 105 dB
- For 1000 MHz - 2000 MHz => SA > 95 dB
- For 2000 MHz - 3000 MHz => SA > 85 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.
With triple shielding cable
They are equipped with a second additional metallic foil that provides extra shielding efficiency, complying with a class A++ shielding attenuation
