| Signal blocking cables with copper conductors, with polyethylene insulation, in PVC compound sheath, with low smoke and corrosive gas emission |
| Designed for electrical installations of railway signaling, centralization, blocking and automation at a rated voltage of 380 V AC at frequency 50 Hz or 700 V DC |
|
|
|
| Cables are used for laying: |
| • in bunches |
| • in premises, dry ducts and tunnels, in corrosive environment |
| • at the sites, where, along with the requirements for flame retardance are specified requirements for low smoke and gas emission at combustion or smoldering |
| • in the absence of mechanical effects on cable |
|
|
|
| Manufacturing of cables with core diameter of 0.8 mm is possible |
|
