Communication cables
Telephone cable TPPepT
Application
The cable is 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 is designed for installation in telephone conduits, mines, along the walls of buildings and suspension on overhead communication towers.
