    3) What Are The Defining Parameters of Cables?

    Uploaded by

    The defining parameters of cables can be broadly classified into three categories: dimensional parameters like conductor size and diameter measurements; insulation material properties like tensile strength and dielectric constants; and current carrying capacity which depends on factors like cable layout, proximity to other cables, and maximum acceptable temperature rise.

    3) What are the defining parameters of cables?

    The defining parameters can be classified broadly into dimensional, insulation


    material properties and current carrying capacity. For dimensional parameters,
    conductor size/number of strands/type of strands, diameter over conductor, diameter
    over insulation, diameter over insulation screen, number and size of neutral
    conductors or tape details (thickness, width & lap type) and diameter over the jacket
    are the defining data. Other important data are: weight/1000 ft length, size of reels
    and length/reel. The insulation/jacket defining parameters are: before an dafter aging
    tensile strength and elongation, hot creep elongation/set, dielectric
    constant,capacitance (SIC) during and after the stability period, insulation resistance
    constant, water absorption properties. The last set of defining parameters are the
    current levels at the nominal voltage under the different operating conditions which
    are function of: the layout and proximity of current carrying cables, the method of
    laying/pulling of cables, provision of future additional loads with their corresponding
    maximum allowable voltage drop and finally the maximum acceptable temperature
    rise & duration for the cable insulating material.
