Water Blocked S14 BU(c) 250 V

Applications

These unarmoured 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

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.
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.
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.
