EN 50288-7 STANDARDS PE Insulated, PVC Sheathed, Individual and Overall Screened & Double Steel Tape Armoured Instrumentation Cables (Multipair)
RE-2Y(St)YDSTAY PIMF 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: PE compound as per EN 50290. 2-23.
• Pairs: Two insulated conductors uniformly twisted together with a lay not exceeding 100mm
• Binder tape: Polyester (PEPT) Tape
• Individual Screen: Aluminium/polyester tape is applied over the laid up pairs metallic side down in contact with tinned copper drain wire, 0.5mm2, covered with extruded PVC.
• Binder tape: Polyester (PEPT) 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: PVC compound as per EN 50290-2-22.
• Amouring: Double steel tape 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.
