Fire retardant cable(Fireguard)
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
Flame Retardance (Single Vertical Wire Test) : BS EN 60332-1-2
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 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.
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: Aluminium/polyester tape+copper wire braid.
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 INDIVIDUAL & OVERALL SCREENED DATABUS CABLE
Conductors: Tinned copper wire, stranded according to IEC 60228 class 2.
