EN 50288-7 Cables

APPLICATION

EN 50288-7 armoured LSZH sheathed cables are generally used when the risk of mechanical damage is

increased. The galvanized steel wire armour provides excellent protection. Generally,EN 50288-7 cables are

used within industrial process manufacturing plants for communication, data and voice transmission signals and

services. Also used for theinterconnection of electrical equipment and instruments, EN 50288-7 LSZH sheath can

reduce toxic smoke and fume emission.

CABLE CONSTRUCTION

Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.

Insulation: Extruded cross-linked XLPE compound, EN 50290. 2-29.

Pairs: Two insulated conductors uniformly twisted together with a lay not exceeding 100mm

Binder tape: PETP transparent tape

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

tinned copper drain wire, 0.5mm²

Inner Sheath: LSZH compound

Amouring: Galvanized steel wire armour

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.). UV resistance, hydrocarbon resistance, oil resistance, anti

rodent and anti termite properties can be offered as option.
