Firetox Flame Retardant Cables 

Firetox Flame Retardant Cables

LSZH Flame Retardant Overall Screened Instrumentation Cables (Multicore)

RE-2X(St)H

APPLICATION

The LSZH sheathed cables are generally used for indoor installation and suitable for wet and damp areas.

Generally, the cables are used within industrial process manufacturing plants for communication, data and voice

transmission signals and services. Also used for the interconnection of electrical equipment and instruments, the

LSZH sheath can reduce toxic smoke and fume emission.

with tinned copper drain wire, 0.5mm². Copper braid screen or aluminium/polyester tape combination with

copper braid screen can be offered as option.

Outer Sheath : Halogen free flame retardant compound to EN 50290-2-27.

Outer Sheath Option : UV resistance, hydrocarbon resistance, oil resistance, anti-rodent and anti-termite

properties can be offered as option.

COLOUR CODE

Insulation Colour : Colours and/or additional ring markings and/or symbols achieved by the use of coloured

insulation or by a coloured surface using extrusion, printing or painting.

Outer Sheath : Black. Other colours can be offered upon request.
