PKM kat.5e 4x2x0,34 mm2 are patch cables, applied in multimedia computer networks
(data, sound and HDTV transmission) including structural wiring of buildings,
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 special polyurethane used for the coating ensures that the cable can operate at low temperatures,
down to -40 °C, and is also resistant to cuts and abrasion.
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 cable’s design allows it to be mechanically unwound and wound without damage,
suspended from natural and artificial supports, and laid on the ground,
as well as traversing water obstacles when submerged in water to a depth of up to 10 meters.
