Plastic coil 250m coaxial cable SK2020plus 18AtC Televes
Plastic coil 250m coaxial cable with live and mesh made of copper (Cu / Cu) with excellent braiding coverage (82%). It is triple shielded (TSH) so it has a second extra sheet of extra armor. An 18AtC cable, of LSFH cover resistant to UV rays. Euroclass B2ca and A ++ class shielding. Televes 413911
Plastic coil 250m coaxial cable SK2020plus 18AtC Televes
Coaxial cable with live and mesh made of copper (Cu / Cu) with excellent braiding coverage (82%). It is triple shielded (TSH) so it has a second extra sheet of extra armor. An 18AtC cable, of LSFH cover resistant to UV rays.
Stands out for
- Conductors made of copper
- Class A++ shielding
- Euroclase B2ca: one of the best CPR categories, taking into account its reaction and resistance to fire
Features
- Exterior coverage of LSFH, UV resistant, in white
- Characteristic impedance of 75 ohm
- Available in reels of different footage
Coaxial cable trishield (TSH) Class A ++
With 3 layers of shielding (trishield), these cables are those that provide greater immunity to interference, as they have a very high screening. Its use is recommended in routes with high levels of electromagnetic noise.
Their constructive properties make them Class A ++, complying with EN 50117:
- At 5 - 30 MHz => TI <0.9 mΩ / m
- At 30 - 1000 MHz => SA> 105 dB
- At 1000 - 2000 MHz => SA> 95 dB
- At 2000 - 3000 MHz => SA> 85 dB
- Where, the transfer impedance (TI) defines the effectiveness of the shielding at low frequencies, and the shielding attenuation (SA) defines it between 30 and 3000MHz.
