APPLICATIONS

FTP kat.5e 4x2x0,5 mm cables are intended for multimedia computer networks (data, sound and HDTV transmission), including structural wiring of buildings, applied in industrial and other dedicated networks sensitive to electromagnetic interferences.

The overall shield protects the cables against external electromagnetic interferences and prevents emission of interferences produced in the cables.

The cables are also applied in computer networks of increased binary transfer where simultaneous transmission in both directions in all 4 symmetrical circuits is used (full duplex, Gigabit Ethernet technique).

The cables are suitable for fixed indoor installations.

CONSTRUCTION

annealed copper single wire conductors of diameter 0.51 mm, 24 AWG,

polyethylene (PE) insulation coloured: white-blue and blue, white-orange and orange, white-green and green, white-brown and brown,

insulated conductors twisted into pairs,

pairs laid-up into a cable core,

collective shield, incorporating an aluminium-polyester tape and an annealed tinned copper single drain wireof diameter 0.5 mm,

PVC cable sheath, grey RAL 7035, other colours also available.

AVAILABLE UPON REQUEST

FTP-H kat.5e 4x2x0,5 mm - halogen free material sheathed cables applied in locations where, in case of fire, higher safety level is required. The cables are flame retardant and their smoke emission is low, emitted fumes are non toxic and non corrosive.
