Flame Retardant RS485 Databus Cables
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 to EIA/TIA 485

Cable Construction
Multipair RS 485 Overall Screened Databus Cable
Conductors: tinned copper wire, stranded according to IEC(EN) 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.
Individual Screen: Individual aluminium/polyester tape.
Overall screen: Copper wire braid.
Outer Sheath: Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1 (Thermosetting LSZHcompound 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.
