Cable:  An assembly of one or more conductors, ether solid or stranded, each covered with a layer of insulating material throughout its length, the whole being provided with a common protective covering. 

Cable Filler : A material used in a multiple-core conductor cable to occupy space and thus round up the cable, sometimes used to accomplish conductor spacing.

Cable Terminal Box:  A box fitted at the end of a cable in order to facilitate the connection, and sometimes the quick disconnection of other conductors.

Calculated Effective Sectional Area: The area of a solid conductor of the same resistivity and having the same resistance as that of any equal length of the conductor. In the case of a split conductor cable, the calculated effective area is the sum of the cross sections of each of the two or more sections into which the conductor is divided.

Compacting : Compact stranding, are conductor constructions that can add little more ampacity into a tight space.

Conductor: A body or substance, which offers a low resistance to the passage of an electric current.

Continuous Vulcanisation (CV) : A continuous, in-line process whereby a wire has an extruded covering applied, is then passed through a tube containing such temperature and pressures as are necessary to complete vulcanisation.

Control Cable : A multi-conductor cable made for operating in control or signal circuits, usually flexible, relatively small in size, and with relatively small current rating.

Core: Assembly comprising a conductor and its own insulation.

Corona Discharge: A phenomenon called corona discharge may occur in high voltage transmission line , resulting in formation of ozone, a highly reactive form of oxygen, and in ionisation of oxygen in the surrounding air. The insulation may be attacked by ozone and by corona

Corona partial discharge may also occur in a void within insulation system where the voltage gradient is sufficiently high.

Cross-Sectional Area:  The sum of the cross-sectional area of the component wires of the conductor of a cable, the cross sectional area of each wire being measured perpendicular to its individual axis.

Current Carrying Capacity: The current a conductor of a given size is capable of carrying safely without exceeding its own temperature limitations, at a defined set of conditions.
