Previous: LSZH Flame Retardant Individual and Overall Screened, Armoured Instrumentation Cables (Multipair)Next: BS EN 50288-7 Multipair Instrumentation Cable, Individual and Overall Screened, XLPE/PVC

APPLICATION

For industrial signal and instrument connections where the route requires added mechanical protection. This multicore cable combines XLPE insulation, an overall foil screen, PVC inner and outer sheaths, and galvanised steel wire armour.

STANDARDS

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

FIRE PERFORMANCE

Flame Retardance (Single Vertical Wire Test) : BS EN 60332-1-2

VOLTAGE RATING

300V, 500V

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. PVC, 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. Copper braid screen or aluminium/polyester tape combination with copper braid screen can be offered as option.

Inner Sheath : Thermoplastic PVC compound according to EN 50290-2-22.

Armouring : Galvanised steel wire.

Outer Sheath : Thermoplastic PVC compound according to EN 50290-2-22.

Outer Sheath Option : UV resistance, hydrocarbon resistance, oil resistance, anti-rodent and anti-termite properties can be offered as option. Compliance to fire performance standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the PVC compound and the overall cable design. LSPVC can also be provided upon request.

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.
