PVC Insulated, PVC Sheathed & Overall Screened Instrumentation Cables (Single Pair)

RE-Y(St)Y 90°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

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

PHYSICAL and THERMAL PROPERTIES

  • Temperature Range During Operation (Fixed State): -30°C – +90°C
  • Temperature Range During Installation (Mobile State): -5°C – +50°C
  • Minimum Bending Radius: 7.5 X Overall Diameter
  • Sunlight Resistance: UL 1581 section 1200
  • Oil Resistance: ICEA S-73-532(Test temperature +60°C, duration 4h. Retention: min 60% of tensile strength/min.60% of elongation)
