APPLICATION:
These multi-element metallic cables are designed for the signal transmission in instrumentation, analogue and digital communication, and control applications in process plants such as those found in the petrochemical and power generation industries. Cables are recommended for indoor and outdoor installations, on racks, trays, in conduits, in dry and wet locations; not for direct burial.
The permissible temperature range:
– during installation: from -5°C to +50°C
– during operation (Y, 2Y): from -30°C to +70°C
– during operation (2X): from -30°C to +90°C
Min. permissible bending radius:
– during operation max. 7,5D
(D – outer diameter of cable)
