- Technical Data
Conductor : Plain or tinned annealed stranded circular copper, IEC 60228, class 2 or class 5
Insulation : B Mica Glass Tape + Hard grade Ethylene Propylene Rubber (HEPR)
Twisting : Color coded cores twisted together to form a pair/triad
Individual Screen : (Code Letter I) Each pair/triple are screened by copper (or aluminium) backed polyester tape in contact with a stranded tinned copper drain wire and wrapped with polyester tape. Pairs/triples are identified by printed numbers on insulated conductors.
Collective Screen : ( Code Letter C) Individually screened pairs/triples are laid-up and collectively screened by copper (or aluminium) backed polyester tape in contact with a stranded tinned copper drain wire.
Outer Sheath : U Flame retardant, halogen-free thermoset compound, SHF2 (Optional SHF MUD)
Color : Grey (if Intrinsically Safe: Blue)
Application
Fixed installation for control, instrumentation and telecommunication in both explosion and safe areas, emergency and critical systems where requirement for fire resistance exists.
