PVC Insulated, PVC Sheathed & Overall Screened Instrumentation Cables (Single
Pair)
RE-Y(St)Y 90°C / 300V
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.
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.
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
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, continuously numbered on white core(1, 2..)for multipair.
Outer Sheath: Black or blue for intrinsically safe systems
