Water Blocked S13 BU(i) 250 V

Applications

These cables are fire resistant, flame retardant, low smoke, halogen-free and mud resistant, used for instrumentation, communication, control and alarm systems.

Standards

IEC 60092-376	IEC 60092-351
IEC 60092-359	IEC 60332-1
IEC 60332-3-22	IEC 60754-1,2
IEC 61034-1,2	NEK 606:2004
IEC 60331-21	VG 95218 part 29

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.
Filler: Water blocking fillers, if required.
Individual Shielding: Each pair/triple 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.
Water Blocking Elements: Water blocking tape and strings for providing longitudinal
water tightness.
Inner Sheath: Halogen-free thermosetting compound, SHF2, coloured grey (blue for intrinsically safe).
Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional, but can not meet low smoke standard.
