Construction

S15 BFOU-HCF(i) 250 V S15 BFOU-HCF(i) 250 V
Conductors Circular tinned annealed stranded copper wire to IEC 60228 class 2.
Insulation Mica tape + Halogen free EPR compound.
Twinning Colour coded cores twisted together.
Individual Shielding Each pairs/triples are screened by copper backed polyester tape in contact with a stranded tinned copper drain wire and wrapped with polyester tape.
Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors.
Bedding Halogen free compound.
Armour Tinned copper wire braid.
Outer Sheath1 Halogen free thermosetting compound, SHF2.
HC-fire protection Extruded thermoplastic fire protection compound.
Taping Lapped glass fibre tape.
Outer Sheath2 Flame retardant halogen-free thermoplastic compound, type SHF1
coloured grey (blue for intrinsically safe).
