Communication cables
Telephone cable TPPep (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.
Cable design
1. Conductor: copper core.
2. Insulation: PE.
3. Core wrapping: synthetic tape.
4. Copper tinned contact wire.
5. Shield material: aluminum foil.
6. Jacket: PVC.
