High-frequency local communication cable KSPPt

kabel-ksppt

Description:
Local communication cable, high frequency with polyethylene insulation and in a polyethylene sheath with a built-in metal rope. Used for laying cable lines for local telephone communication.

    Required cable section

    Number in meters

    Construction:
    Conductive core – copper round wire.
    Insulation – polyethylene.
    The nominal insulation thickness is:
        for cores with a diameter of 0.9 mm – 0.95 mm (total cable diameter 14 mm)
        for cores with a diameter of 1.2 mm – 0.8 mm (total cable diameter 14 mm)
    Four insulated conductors are stranded in a “four”.

    In the “four”, two diagonally located conductors form a working pair, the insulation of the first pair of the four has a natural color, the second pair is blue.
    The belt insulation is made of extruded polyethylene with a nominal thickness of 0.8 mm.
    The screen is made of aluminum-polyethylene tape. A contact tinned copper wire with a nominal diameter of 0.3–0.4 mm is laid under the screen.
    Rope – steel, with a nominal diameter of 2.6 mm
    A polyethylene sheath with a nominal thickness of 1.8 mm is applied simultaneously to the cable core and rope steel.

    Decipher the “KSPPt” wire as follows:
    K – Cable
    S – communication
    P – Polyethylene insulation
    P – Polyethylene sheath
    t – presence of a rope steel

    Exploitation:
    High-frequency local communication cable is intended for inter-office and subscriber communication lines of telephone networks, with transmission systems with time division of channels and pulse-code modulation with a transmission rate of up to 2048 kbit / s, with a remote power supply voltage of up to 500 V DC.
    KSPPt cables are designed for suspension on supports of overhead transmission lines.
