APPLICATION

For indoor industrial signal circuits requiring screening around each pair as well as the complete cable assembly. This unarmoured instrumentation cable uses XLPE insulation and an LSZH sheath for interconnections between instruments and electrical equipment, including damp locations.

STANDARDS

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

FIRE PERFORMANCE

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. 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).

Individual Screen : Aluminium/polyester tape is applied over each pair with metallic side down in contact with tinned copper drain wire, 0.5mm².

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.
