| This cable is used for interconnecting between frames of PCM equipments |
| with 120W characteristic impedance. |
 Conductor： |
| Annealed bare copper or tinned copper |
| Insulation： |
| Foamed PE / HDPE |
| Shielded： |
| Two wires are twisted to form a pair then shielded with a layer of Al-Mylar |
| foil. A piece of tinned copper wire is added along with the pair as drain wire. |
| Assembly： |
Suitable number of pairs are assembled to form a cable core.
|
| Overall shield： |
| a. Layer of Al-Mylar foil with a drain wire. |
| Sheath： |
| PVC (polyvinyl Chloride)or LSNHFRPE.( ow-moke Non-Halogen Flame Retardant Polyethylene). |
