EN 50288-7 Cables

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 outdoor installation, on racks, trays, in conduits, in dry and wet
locations; not for direct burial.
Recommended for use as fire protection measure for people and important material assets.

CABLE CONSTRUCTION

Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.
Insulation: Extruded cross-linked XLPE compound as per EN 50290-2-29.
Triple: Three conductors twisted to form a triple
Lay-up: Triples laid up in layers of optimum pitch
Separator: Polyester tape
Overall Screen: Aluminium/polyester tape with tinned copper drain wire, 0.5mm2
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.
