    RS485 Data Cable RE-02Y(St)H 1P18A

    APPLICATIONS

    The cables are designed for RS485 data connections. This cable combines low capacitance insulation with one of the highest levels of screening to provide high speed, interference free, data transmission where continued functionality is required during a fire situation.

    STANDARDS

    Basic design EIA/TIA 485
    Halogen Free IEC 60754-1
    No corrosive gas emission IEC 60754-2
    Minimum Smoke Emission IEC 61034-1/2
    Reduced Fire Propagation IEC 60332-3C / NF C 32070-2.2 (C1)
    Flame Retardance IEC 60332-1 / NF C 32-070-2.1 (C2)
    Fire Resistance IEC 60331-23 / NF C 32-070-2.3(CR1)

    VOLTAGE RATING

    300/500V

    CONSTRUCTION

    Conductors : tinned annealed copper wire, stranded according to IEC(EN) 60228 class 2 or class 5.

    Insulation : Solid or foam PE compound

    Cabling Elements : Insulated cores are twisted to form pairs with varying lay length to minimize crosstalk.

    Overall screen : Aluminum/ polyester tape with tinned copper drain wire.

    Fire Barrier : Fireproof Tape.

    Outer Sheath : Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1.

    ELECTRICAL PROPERTIES

    Dielectric test 1000 V r.m.s. for 5’ (core-core)
    1000 V r.m.s. for 5’ (core-screen)
    Impedance 120Ω
    Capacitance 45 nF/km conductor to conductor
    90 nF/km conductor to shield

    PHYSICAL AND THERMAL PROPERTIES

    Temperature range during operation (fixed state) : -30°C – +90°C

    Temperature range during installation (mobile state) : -20°C – +50°C

    Minimum bending radius : 8 × Overall Diameter
