- Technical Data
Conductor : Tinned annealed stranded circular copper, IEC 60228 class 2
Insulation : (Code Letter B) Mica Glass Tape + Ethylene Propylene Rubber (EPR)
Twisting : Color coded cores twisted together to form a pair/triad
Collective Screen : (Code Letter C) Pairs/triples are laid-up and collectively screened by copper backed polyester tape in contact with a stranded tinned copper drain wire. Pairs/triples are identified by printed numbers on insulated conductors.
Outer Sheath : (Code Letter U) Flame retardant, halogen-free thermoset compound, SHF2 (Optional SHF MUD)
Color : Grey (if Intrinsically Safe: Blue)
