BS EN 50288-7 Fire Resistant Overall Screened Instrumentation Cables (Multicore)

RE-2X(St)H...CI

Fire Resistant Overall Screened Instrumentation Cables (Multicore)

APPLICATION

The BS EN 50288-7 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.

STANDARDS

Basic design to BS EN 50288-7 (formerly BS 5308)

FIRE PERFORMANCE

Circuit Integrity IEC 60331-21; BS 6387 CWZ (Optional); BS EN 50200 (PH30/PH60/PH120)
Flame Retardance (Single Vertical Wire or cable test) IEC 60332-1-2; EN 60332-1-2
Halogen Free IEC 60754-1; EN 50267-2-1
No Corrosive Gas Emission IEC 60754-2; EN 50267-2-2
Minimum Smoke Emission IEC 61034-2; EN 61034-2

VOLTAGE RATING

300, 500V

CABLE CONSTRUCTION

Conductor: Plain or metal coated copper wire, solid, stranded or flexible according to IEC 60228 class 1, 2 and class 5.
Fire Barrier: Mica glass tape.
Insulation: Extruded XLPE compound according to EN 50290-2-29. LSZH, PE, PP compound can be offered as options.
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.
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.
