RE-2Y(St)Y 90°C / 300 V

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 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.

STANDARDS

CABLE CONSTRUCTION

Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.
Insulation: PE compound as per EN 50290. 2-23.
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.

COLOUR CODE

Insulation: Black / White / Red, continuously numbered on white core(1, 2..)for multitriples.
Outer Sheath: Black or Blue for intrinsically safe systems
