Communication cables
Telephone cable TPPepZ (pair)
Application
Designed for operation in local primary communication networks and communication lines with a nominal voltage of remote power supply up to 145 V AC at a frequency of 50 Hz or voltage up to 200 V DC.
The cable can be used for installation in telephone sewers, in sewers, mines, along the walls of buildings and suspension on overhead communication lines in cases of high humidity.
Cable design
1. Conductor: copper core.
2. Insulation: PE.
3. Core wrapping: synthetic tape.
4. Copper tinned contact wire.
5. Core filling: hydrophobic gel.
6. Shield material: aluminum foil.
7. Jacket: PVC.
