APPLICATIONS

This series of cables features fire resistance, flame retardancy, low smoke, zero halogen, and mud resistance, specifically designed for instrument, communication, control, and alarm systems. They are particularly suitable for harsh environments such as offshore platforms, ships, and other marine engineering applications.

CONSTRUCTION

Electrical Characteristics

ConductorsCircular tinned annealed stranded copper wire to IEC 60228 class 2.
InsulationMica tape + Halogen free EPR compound.
TwinningColour coded cores twisted together.
Individual ShieldingEach 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.
BeddingHalogen free compound.
ArmourTinned copper wire braid.
Outer SheathHalogen free thermosetting compound, SHF2 (for TYPE S3).

Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S3/S7), coloured grey (blue for intrinsically safe).
