Communication cables
Alarm and blocking Cable SBVBBSHV
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 380V or a constant voltage of 700V.
The cable can be used for installation in dry channels and tunnels, in an aggressive environments, without significant mechanical effects on the cable.
