APPLICATION:
The signal cables must be suitable for general use as underground cable in signal systems, unless the use of special cables of signaling technology (e.g. PZB cable) is prescribed, preferably for transmission of direct current at a an operating voltage ≤600 V and alternating current up to approx. 100 Hz during an actual operating voltage ≤420 Veff.
The permissible temperature range:
– during installation: from -10°C to +60°C
– during operation: from -40°C to + 60°C
Min. permissible bending radius:
– during operation min. 20D
