F/UTP CAT.5E LSZH (IEC STNDARD)

CABLE CONSTRUCTION
Conductor: The conductors shall be solid , annealed and bare copper with a diameter of AWG24 and minimum acceptable diameter shall be 0.485mm.
Insulation: Each conductor shall be insulated with solid high density polyethylene. The insulation shall be uniform and shall not have any defects. The diameter over the insulation shall be maximum 1.22mm.
Screen: The aluminum tape coated on one side with plastic film shall be applied over the cable core for screening on jacketing process. A tinned copper wire with the diameter of 0.4mm shall be applied with cable core in jacket.
Sheath: The flame retardant PVC or LSZH(Low Smoke Zero Halogen) compound colored grey or other colors shall be applied over the screening.
