APPLICATION 

En 50228-7 cables are used for transmission of analogue and digital signals in instrument and control systems; allowed for use in zone 1 and zone 2, group II, classified areas (IEC 79-14), not allowed for direct connection to low impedance sources, e.g. public mains electricity supply.
Recommended for indoor and outerdoor installation, on racks, trays, in conduits, in dry and wet
locations; not for direct buiral.
Recommended for use as fire protection messure for people and important material assets.

CABLE CONSTRUCTION

Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.
Insulation: PE compound as per EN 50290. 2-23.
Overall Screen: Aluminium/polyester tape with 0.5mm2 screen (7/0.3mm) tinned copper drain wire.
Inner Sheath(optional): PVC compound
Armouring(optional): Galvanised steel wire
Outer Sheath: Thermoplastic PVC compound as per EN 50290-2-22. 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.
