3Definitions
For the purpose of this standard, the following definitions apply.
3.1Definitions concerning cables
3.1.1
insulated cable
assembly consisting ofone or more cores;
individual covering(s) (if any);assembly protection (if any);- protective covering(s) (if any).
Additional uninsulated conductor(s) may be included in the cable
3.1.2
radial field cable
cable in which each core is covered with an individual screen
3.1.3
screen
conducting layer(s) having the function of control of the electric field within the insulation. Itmay also provide smooth surfaces at the boundaries of the insulation and assist in theelimination of spaces at these boundaries
3.1.4
conductor
part of the cable which has the specific function of carrying current
3.1.5
stranded conductor
conductor consisting of a number of individual wires, all or the major part of which should havea helical form
NOTE The stranded conductor may be circular or shaped.
3.1.6
core
assembly comprising a conductor and its own insulation
3.1.8shield
surrounding earthed metallic layer to confine the electric field within the cable and/or to protectthe cable from external electric influence
3.1.9
flexible cable
cable which is required to be capable of being flexed while in service,and of which thestructure and materials are such as to fulfil this requirement
3.1.10
cord
flexible cable with a limited number of conductors of small cross-sectional area
3.1.11
length of lay
axial length of one complete turn of the helix formed by one of the cable components
3.1.12
separator
thin layer，used as a barrier to prevent mutually detrimental effects between differentcomponents of a cable, for example between conductor and insulation or between insulationand sheath
3.1.13
filler
material used to fill the interstices between the cores of a multiconductor cable
3.1.14
inner covering
non-metallic covering which surrounds the assembly of the cores (and fillers，if any) of amulticore cable and over which the protective covering is applied
3.1.15
sheath
uniform and continuous tubular covering consisting of non-metallic material, generally extruded
3.1.16
oversheath
non-metallic sheath applied over a metallic covering, constituting the outermost sheath of thecable
