Communication cables
Signal and blocking cable SBPBBSHP
Application
The cable is designed for railway circuits, electrical installations of signaling, centralization, blocking, fire alarm, telegraph and automation with a rated alternating voltage of 380 V or a constant voltage of 700 V.
The cable can be used for installation in the ground (in trenches) in a highly aggressive environment without significant mechanical effects on the cable.
Cable design
1. Conductor: copper core.
2. Insulation: PE.
3. Core wrapping: synthetic tape.
4. Inner sheath: PE.
5. Shield material: aluminum foil.
6. Jacket: UV stabilized PE.
