Water Blocked S16 BFOU-HCF(c) 250 V

Water Blocked S16 BFOU-HCF(c) 250 V

Applications

These cables are partially water blocked, fire resistant, flame retardant, low smoke and halogen free, used for emergency instrumentation, communication, control and alarm systems that need to be operational during a 1100˚C hydrocarbon fire.

Standards

Construction

Conductors: Circular tinned stranded copper wire to IEC 60228 class 2.
Insulation: Mica tape + Halogen free EPR compound.
Twinning: Colour-coded cores twisted together.
Collective Shielding: Pairs/triples are layed up and collectively screened by copper-backed polyester tape in contact with a stranded tinned copper drain wire. Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors.
Filler: Water blocking fillers, if required.
Bedding: Halogen-free compound, PETP wrapping tape will be applied over the bedding, if required.
Armour: Tinned copper wire braid, PETP wrapping tape will be applied over the braiding, if required.
Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
Inner Sheath: Halogen free thermosetting compound, SHF2.
HC-fire protection: Extruded thermoplastic fire protection compound.
Taping: Lapped glass fibre tape.
Outer Sheath 1: Flame retardant halogen-free thermoplastic compound, type SHF1, coloured grey (blue for intrinsically safe).
Outer Sheath 2: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
