Strictly halogen free, FLAMEX EN 50306-3 & -4 control cables combine the advantages of small size, lightweight, high chemical resistance, high mechanical properties. They are recommended for installation in railway vehicles (locomotives, trains, trolleybusses...).

DESIGN

1. Conductor
Stranded tinned copper wires
Colour: white, numbered 1 to n 

2. Insulation
Thin wall, cross-linked halogen free material

3. Screen (for screened versions)
Tinned copper braid with optional polyester tape

4. Outer sheath (for sheathed versions)
Cross-linked halogen free material
Colour: black


Example of marking: FLAMEX 239 EN 50306-3 - 300 V - number of cores x cross-section - MM-S-90 - week/year batch number
