Application

Halogen-free signal cable with improved properties under fire, suitable for different applications in control and measuring circuits, in industry and facilities where human lives or valuable property need to be protected against damages caused by fire. Concentric copper conductor serves as screen against electromagnetic impact. Suitable for fixed and mobile installation, but free of mechanical stress; for dry and damp environment, not for outdoor application. Resistant to majority of most frequently used oils.

advantages:
– halogen-free, no release of toxic or corrosive gases under fire
– reduced smoke occurrence under fire
– no flame propagation in vertical cable bundle
