Communication cables
Telephone and radio cable PRPPM
Application
Designed for operation at voltages up to 380 V with a frequency of up to 10 kHz on subscriber telephone lines and distribution networks.
The cable can be used for installation in soil, telephone conduits, collectors, on the outer walls of buildings. It is allowed to lay on the supports of overhead communication towers in areas not subject to strong ice and winds.
Cable design
1. Conductor: copper core.
2. Insulation: PE.
3. Jacket: UV stabilized PE.
