Water Blocked S15 BFOU-HCF(i) 250 V

Construction

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.

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.
