Water Blocked S13 BU(i) 250 V

Applications

Water Blocked S13 BU(i) 250 V 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

• l???? Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
  l???? Insulation: Mica tape + Halogen free EPR compound.
  l???? Twinning: Colour coded cores twisted together.
  l???? Filler: Water blocking fillers, if required.
  l???? 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.
  l???? Filler: Water blocking fillers, if required.
  l???? Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
  l???? Inner Sheath: Halogen free thermosetting compound, SHF2, coloured grey (blue for intrinsically safe).
  l???? Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
