Flame Retardant Twisted Pair Cable Comply to:IEC60332-3


These cables are specially designed for requirements concerning the smoke density and acidic gas emitted in

case of fire. FIRETOX Cables are made with well chosen materials that not only can fulfill the conventional

requirements of Low Smoke Halogen Free, but also can reduce flame propagation in those instance where fire

may develop.


Conductor:Stranded annealed copper/tinned copper wires to BS 6360, class 2

Insulation:  Low smoke,zero halogen (LSZH) insulated

Nominal thickness: 0.4-0.5 mm

Twisting:Two colored insulated conductors are uniformly twisted together to form a pair.

Screen:Overall Aluminium/Polyester tape applied with the metallic side down in electrical contact with a 0.5 mm2

tinned copper drain wire(7*0.31mm formation).

A 23 micron polyester tape is applied over the screening tape with a minimum 50% overlap.
