Flame Retardant Multi-core Instrument Cable Comply to:IEC60332-3

6C×20AWG TC/ LSZH/ Wrapping/ OS/ FR LSZH

Application:

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.

Construction:

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

Insulation:Low smoke,zero halogen (LSZH) insulated

Nominal thickness: 0.4 mm

Wrapping:Polyester tape

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.

Sheathing:Flame retardant LSZH with anti-termite and anti-rodent additive

Nominal thickness: 0.7mm

Overall diameter: 6.59+/-0.2mm

Packing: The cables are delivered on non-returnable wooden drums.
