Application As control and connector cable in safety areas in railway rolling stock with circuit integrity resistance and mineral oil and fuel resistance.
Marking continuos printing in contrasting colors (manufacturer identification) + type identification t intervals of 500 mm resp. manufacturers identification thread
Core colours up to 10 cores colored; core: 1- white, 2-brown, 3-blue, 4-black, 5-red, 6-yellow, 7-green, 8-grey, 9-orange, 10 violet; > 10 cores: all cores black with numbers
Standards DIN 5510 part 1 Hazard level 1 - 4 EN 50200 15 min. BS 6387 AXSZ
Design
Conductor/ core: tinned copper strands
Insulation: one layer of mica tape, over-lapped, halogen free flame retardent cross linked polymer
Stranding: several wires were stranded together in concentrical layers. Filling elements or pads out of halogen free, flame retardant material are allowed.
Wrapping: admissible layer, e.g. glass sheet or foil
Screening: tinned copper braid, optical coverage approx. 85%. If necessary a additional Aluminium luminated plastic foil is used.
Seperator: halogen free tape or foil overlapped admissible
Outer sheath: cross-linked, mineral oil and fuel resistant HFFR- Polyolefin compound
