Firetox Flame Retardant Cables 


Firetox Flame Retardant Cables

LSZH Flame Retardant Overall Screened Instrumentation Cables (Multipair)

RE-2X(St)H

APPLICATION

The unarmoured 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.

CABLE CONSTRUCTION

Conductor : Plain or metal coated copper wire, solid, stranded or flexible according to IEC 60228 class 1, 2 and

5.

Insulation : Extruded XLPE compound according to EN 50290-2-29. LSZH, PE, PP compound can be offered as

options.

Pairs : Two insulated conductors uniformly twisted together with a lay not exceeding 100mm (≤1.5mm²) or

150mm (for 2.5mm²).

Binder tape : PETP transparent tape.

Overall Screen : Aluminium/polyester tape is applied over the laid up cores with metallic side down in contact

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 : Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1 (Thermosetting LSZH compound

type SW2-SW4 as per BS 7655-2.6 can be offered).

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.
