koaxiálny kábel Televes SK125plus 100 m biely

Coaxial Cable Televes SK125plus 100 m White is a 75 Ω coaxial cable designed for reliable signal transmission over long runs. The cable features both conductors made of copper (Cu/Cu), a PVC sheath and a triple-shielded (Trishield) structure with an additional foil layer and a braid coverage of 55%, which increases immunity to electromagnetic interference and reduces signal loss. It is suitable for indoor and outdoor installations and complies with EN 50117 Class A+ structural requirements.

Advantages

The SK125plus cable combines copper conductors, a PVC jacket and three shielding layers to provide low transfer impedance at low frequencies and high shielding attenuation across a wide radio frequency range. Its construction delivers enhanced protection against electromagnetic noise and ensures consistent signal quality for audio, video and broadcast applications.

Suitable for

• TV and FM distribution networks
• Satellite and terrestrial antenna cabling
• CCTV video transmission
• Indoor and outdoor installations requiring high shielding

How to use

Run the coaxial cable between devices or distribution points, avoiding sharp bends and tight kinks. Strip the outer sheath and shielding carefully to expose the dielectric and central conductor, then terminate with appropriate 75 Ω connectors or fusion/pressed fittings following manufacturer instructions. Maintain separation from high-voltage power lines where possible and secure the cable with appropriate clips or ties to prevent mechanical stress.

Recommendations

For installations in areas with high electromagnetic interference, use the SK125plus triple-shielded cable to maintain signal integrity. Ensure proper connector termination and grounding of the shield to maximise the cable’s shielding performance.
