Conductor: Stranded tinned annealed copper wires as per IEC 60228, Class 2
Fire Resisting Layer: Mica/glass tape
Insulation: HF EPR as per IEC 60092-351
Twisting: Two/Three Insulated cores shall be twisted together to form a pair/triad
Individual Screen:
• Screened by copper or aluminium backed polyester tape with tinned copper drain wire.
• Each pair/triad is wrapped with polyester tape to prevent electrical contact with adjacent pairs/triads.
Cabling:
• Screened pairs/triads shall be cabled.
• Flame retardant & non-hygroscopic fillers may be used.
• Suitable tape(s) may be applied on the cabled core.
Sheath:
• SHF2 or SHF MUD as per IEC 60092-359
• Outer sheath color: Grey
• Any other color scheme may be applicable when purchaser required.
