SF/UTP Cat 5e

General information

It consists of four twisted pairs, which are covered with a protective tape, a drain wire and an aluminum opolymer tube. A tube looking as a braid of copper wire and an outer protective shell are superimposed onto the conductor with aluminum opolymer tube. Category: 5e.

Materials:

Electric conductor: soft copper

Insulation: high density polyethylene

Outer protective sheath: PVC/LSZH (grey color)

Protective tape: PTFE tape

Screen: aluminum polymer tape and tinned copper wire

Drain wire: tinned copper wire

STRUCTURAL DESIGN:

  1. Drain wire
  2. The twisted pair
  3. Protective tape
  4. Foil screen
  5. Braid screen
  6. The outer sheath

SPECIFICATIONS:

  • The diameter of the copper conductor: 0.51 mm (AWQ24)
