Communication cables
Cable signaling and blocking SBPu
Application
The cable is designed for electrical communication systems and railway signaling, centralization, interlocking 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 an aggressive environment without significant mechanical effects on the cable.
Cable design
1. Conductor: copper core.
2. Insulation: PE.
3. Wrapping: synthetic tape.
4. Sheath: PE.
5. Jacket: UV Stabilazed PE.
