Control cable KVVGEng of 0,66 kV

kontrolnyj-kabel-ekranirovannyj-kvvge

Description:
Control cable with copper conductors with PVC insulation, shielded, in PVC sheath (ng – flame retardant). The non-flammable design, which distinguishes the control cable kvvgeng, allows it to be used in rooms with a high fire hazard class. The plastic compound, which is the main material of the insulating winding, does not support combustion.

    Required cable section

    Number in meters

    Design:
    1. Conductor – copper, single-wire, class 1
    2. Insulation – made of polyvinyl chloride plastic (PVC).
    3. Stranding – the insulated conductors of the cables are stranded. Each layer contains a counting pair, the insulated veins of which differ in color from each other and from the rest of the veins.
    4. Separating layer – applied to twisted conductors made of polyethylene terephthalate film or PVC compound with a thickness of at least 0.5 mm, in cables of the KVVGEng brands and made of PVC compound of low flammability with a thickness of at least 0.5 mm.
    5. Screen – in the form of a winding of copper foil or copper tape with a nominal thickness of 0.06 mm, or an aluminum foil with a nominal thickness of 0.1 0.15 mm with an overlap to ensure the continuity of the screen at permissible bending radii of the cables. It is allowed to manufacture the screen from corrugated aluminum strips applied longitudinally with overlapping. A copper wire with a diameter of 0.4 – 0.6 mm is laid longitudinally along the screen made of aluminum foil.
    6. Sheath – PVC compound which does not support combustion.

    Application:
    Designed for fixed connection to electrical devices, devices, assemblies of clamps of electrical switchgear with rated alternating voltage up to 660 V, frequency up to 100 Hz or constant voltage up to 1000 V, for laying in rooms, channels, tunnels in the absence of mechanical stress on the cable in aggressive conditions environment and the need to protect electrical circuits from the influence of external electric fields. KVVGEng cables are used for laying in cable structures and premises to ensure fire safety of cable chains when laying in bundles.

    Specifications:
    Working ambient temperature: from -50 ° С to + 50 ° С
    Relative humidity at + 35 ° С: 98%

    Nominal insulation thickness for conductors with cross-section:
    0.75 – 2.5 mm2 – 0.6 mm
    4 – 6 mm2 – 0.7 mm
    10 mm2 – 0.9 mm

    Electrical resistance of conductor insulation at a temperature of 20 ° C with a cross-section:
    0.75 – 1.5 mm2 – not less than 10 MOhm * km
    2.5 – 4.0 mm2 – at least 9 MOhm * km
    6 mm2 – not less than 6 MOhm * km
    Long-term permissible core heating temperature during operation: + 70 ° С
    The cables are resistant to assembly bends.
    The bending radius of non-armored cables with copper conductors when laid at an ambient temperature of at least 0 ° С is:
    for cables with outer diameter up to 10 mm incl .: at least 3 cable diameters
    for cables with an outer diameter of 10 – 25 mm incl .: at least 4 cable diameters
    Bending radius of non-armored cables during laying and installation without preheating at an ambient temperature of at least -15 ° С: at least 6 cable diameters

    Life time:
    when laying in the ground (trenches) and on overpasses, not less than: 15 years;
    when laying in rooms, channels, tunnels, not less than: 25 years.
