TV distribution cables

PRESENTATION

VATC cables are used for wave-broadcasting radios as well as analogical and numerical televisions for frequencies from 5 to 3000 MHz

REFERENCE STANDARDS

UTE C 90-130

CABLE STRUCTURE

1- Conductors :

Conductors consist of solid copper.

2- Dielectric

Conductors are insulated by a physical cellular polyethylene layer.
The thickness of insulation is such that the elctrical requirements are net.

3- Screen

On the cable core cover there is aluminum tape covered on one side by a polyethylene layer and a tinned copper braid.

4- Outer sheath

The sheath, consists of PVC, is complying with NF EN50290-2-22 standards. . It is unleaded and flame retardant and not spread flames (Category C2 according to NFC 32070 2.1) and resists to UV rays. It may be without halogens.

5- Marking on the sheath

Each meter the sheath has on a generator the following message:
TUNISIE-CABLES 17 VATC ss/aa + metric marking (000001.m)
17: type representing Attenuation in dB/100m (example: 23; 17;19)
ss: week number
aa: year in 2 figures
Metric marking: xxxxxx m (6 characters followed by “m” for meters)
