Water Blocked S14 BU(c) 250V

Applications

Water Blocked S14 BU(c) 250 Vunarmoured cables are partially water blocked, fire resistant, flame retardant, low smoke and halogen free, 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???? 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.
  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.
