Signal and blocking cable SBZPu

Кабель сигнально-блокировочный СБЗПу

Application

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, in conditions of high humidity..

Cable design

1.Conductor: copper core.
2. Insulation: PE.
3. Core wrapping: synthetic tape
4. Core filling – thixotropic gel.
5. Sheath: PE.
6. Jacket: UV stabilized PE.
