    LSZH Flame Retardant RS 485 Databus Cables

    i
    • Flame Retardant RS 485 Databus Cable
    • LSZH RS485 Databus Cable

    APPLICATION

    The cables are designed for RS 485 data connections where continued functionality is required during a fire situation. 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 adapted to EIA/TIA 485

    FIRE PERFORMANCE

    Flame Retardance (Single vertical wire or cable test) IEC 60332-1-2; EN 60332-1-2
    Reduced Fire Propagation (Vertically-mounted bundled wires & cables test) IEC 60332-3-24; EN 60332-3-24
    Halogen Free IEC 60754-1; EN 50267-2-1
    No Corrosive Gas Emission IEC 60754-2; EN 50267-2-2
    Minimum Smoke Emission IEC 61034-2; EN 61034-2

    CABLE CONSTRUCTION

    MULTIPAIR RS 485 OVERALL SCREENED DATABUS CABLE

    Conductors : Tinned copper wire, stranded according to IEC 60228 class 2.

    Insulation : Foam PE or foam skin PE.

    Cabling Elements : Insulated cores are twisted to form pairs with varying lay length to minimize crosstalk. Two pair cable had four cores laid in quad formation.

    Cabling : Pairs are cabled together in concentric layers.

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

    Outer Sheath : Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1 (Thermosetting LSZH compound type SW2-SW4 as per BS 7655-2.6 can be offered).

    Outer Sheath Option : UV resistance, hydrocarbon resistance, oil resistance, anti-rodent and anti-termite properties can be offered as option.

    MULTIPAIR RS 485 OVERALL DOUBLE SCREENED DATABUS CABLE

    Conductors : Tinned copper wire, stranded according to IEC 60228 class 2.
