Cable UTP CAT5E CU 2х4х0,50

Description:
Twisted pair is a type of communication cable. Represents one or more pairs of insulated conductors, twisted together (with a small number of turns per unit length), covered with a plastic sheath.

    Required cable section

    Number in meters

    Construction:

    1. Conductive core (TPZH): annealed copper wire (TPZH diameter 0.5mm) (conductor diameter 0.9mm) (cable diameter / size 4.8mm)
    2. Insulation: solid, PE
    3. Pair: two insulated conductors twisted together with matched pitches and with the following color identification:
    – pair 1: white-blue/blue
    – pair 2: white-orange/orange
    – pair 3: white-green/green
    – pair 4: white-brown / brown
    4. Sheath: PVC, LSZH or LSFRZH

    Exploitation:

    Used in telecommunications and computer networks as a physical signal transmission medium in many technologies, such as Ethernet, Arcnet, Token ring, USB. Twisted pair cable is often referred to as “internet cable”. Currently, due to its cheapness and ease of installation, it is the most common solution for building wired (cable) local area networks.

    UTP cable connects to network devices using 8P8C connector (also called RJ45).

    Main technical and operational characteristics:
    Temperature Range:
    – during installation: -10 °C…+60 °C
    – during exploitation: -20 °C…+60 °C
