Flame Retardant RS485 Databus Cables

APPLICATION

The cables are designed for RS485 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

Cable Construction

MULTIPAIR RS 485 OVERALL SCREENED DATABUS CABLE
Conductors: Tinned copper wire, stranded according to IEC 60228 class 2 or class 5.
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 PVC compound.
Outer Sheath Option: 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.

MULTIPAIR RS 485 OVERALL DOUBLE SCREENED DATABUS CABLE
Conductors: Tinned copper wire, stranded according to IEC 60228 class 2 or class 5.
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.
