Application :- High-quality co-axial for cable TV network with notch-free attenuation values over a wide range of frequencies. The special jacketing offers increased life even in rugged conditions.
Cable Construction :-
- Conductor: The central conductor is made of solid electrolytic grade annealed plain copper, which has distinct advantages over traditional copper conductors.
- Insulation: The insulation provided over the conductor is of foam PE, which acts as a dielectric.
- Screen: Aluminium mylar tape is provided over the insulated conductor to shield the conductor and ensure disturbance-free transmission of signals.
- Braiding: The braiding is generally provided with 60% coverage of ATC (Annealed Tinned Copper) / Al alloy.
- Marking: The cables are marked ‘RATNA CO-X’.
Cable Design Parameters :- Kindly complete the part numbers for these cables by adding the suffix (in place of ‘xx’) for the colour required: 01 – green, 02 – black, 03 – red, 04 – blue, 05 – yellow, 06 – grey, 07 – white.
