PE/PE railway safety ground cables, screened, armoured
Railway Signalling and Telecommunications Cables
The cables are waterproof and designed for retraction into conduits, for laying in the ground and in the outside environment for railway telecommunications and control signal systems where elevated mechanical stress requirements are increased. They are highly resistant to the effects of external electromagnetic fields.
