Communication cables
Cable signal and blocking SBEVG
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 indoor installation, in dry channels and tunnels, in an aggressive environments without significant mechanical effects on the cable and, if necessary, protecting electrical circuits from the influence of external electric fields.
Cable design:
1. Conductor: copper core.
2. Insulation: PE.
3. Wrapping: synthetic tape.
4. Shield material: aluminum foil.
5. Copper tinned contact wire.
6. Jacket: PVC.
Design Versions:
1. Outer sheath: LSZH.
