EN 50288-7 Cables
PE Insulated, PVC Sheathed & Overall Screened, Armoured Instrumentation Cables (Single Pair)
RE-2Y(St)YSWAY 70°C / 300V
APPLICATION
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
Basic design to EN 50288-7

CABLE CONSTRUCTION
- Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.
- Insulation: PE compound as per EN 50290. 2-23.
- 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
- Inner Sheath: Thermoplastic PVC compound as per EN 50290-2-22.
- Amouring: Galvanized steel wire armour
- 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
PHYSICAL and THERMAL PROPERTIES
- Temperature Range During Operation (Fixed State): -30°C – +70°C
- Temperature Range During Installation (Mobile State): -5°C – +50°C
