Communication cables
Telephone cable TPPepZBbShp (double paired)
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 soils of all categories (except mechanized - in rocky soils) that are not subjected to permafrost deformations.
