EN 50288-7 STANDARDS PE Insulated, PVC Sheathed, Overall Screened & Armoured Instrumentation Cables (Single Triple)

RE-2Y(St)YSWAY 70°C / 300 V

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

EN50288-7

  • Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.
  • Insulation: PE compound as per EN 50290. 2-23.
  • Pair: Two conductors twisted to form a pair
  • Lay-up: Pairs laid up in layers of optimum pitch
  • Separator: Polyester tape
  • Overall Screen: Aluminium/polyester tape with tinned copper drain wire, 0.5mm2
  • Inner Sheath: Thermoplastic PVC compound
  • Armour: Galvenized round steel wire, EN 10257-1
  • 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

PHYSICAL and THERMAL PROPERTIES

  • Temperature Range During Operation (Fixed State): -30°C – +70°C
  • Temperature Range During Installation (Mobile State): -5°C – +50°C
