APPLICATION
EN50228-7 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.
STANDARDS
Basic design to EN 50288-7

CABLE CONSTRUCTION
Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.
Insulation: PVC compound as per EN 50290-2-21.
Pair:Two conductors twisted to form a pair
Lay-up: Pairs laid up in layers of optimum pitch
Separator: Polyester tape
Overall Screen: Tinned copper wire braid
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.
COLOUR CODE
