Term Description
D.C. Abbreviation for "Direct Current"
Data Processing Cable UL (Underwriter's Laboratories) Standard 1690; National Electrical Code (NEC) Article 645 of NFPA 70
Decibel (dB) A unit to express difference of power level. Used to express power gaining amplifiers or power loss in passive circuits of cables.
Delay Line A cable made to provide very low velocity of propagation with long electrical delay for transmitted signals
Derating Factor A factor used to reduce the current carrying capacity of a wire when used in environments other than that for which the value was established
Dielectric Any insulating material between two conductors which permits electrostatic attraction and repulsion to take place across it
Dielectric Absorption The property of an imperfect dielectric whereby there is an accumulation of electric charges within the body of the material when it is placed in an electric field
Dielectric Breakdown The voltage at which a dielectric material is punctured, which is divisible by thickness to give dielectric strength
Dielectric Constant (K) The ratio of the capacitance of a condenser with dielectric between the electrodes to the capacitance when air is between the electrodes (also called Permittivity and Specific Inductive Capacity)
Dielectric Strength The voltage which an insulation can withstand before breakdown occurs. Usually expressed as a voltage gradient (such as volts per mil).
Dielectric Test A test in which a voltage higher than the rated voltage is applied for a specified time to determine the adequacy of the insulation under normal conditions
Direct Burial Cable A cable installed directly into the Earth
Direct Capacitance The capacitance measured directly from conductor to conductor through a single insulating layer
Direct Current (DC) An electric current which flows in only one direction
Direct Current Resistance (D.C.R.) The resistance offered by any circuit to the flow of direct current
Dissipation Factor The tangent of the loss angle of the insulating material (also referred to as loss tangent, tan S, and approximate power factor)
Double Foot The combined length of one linear foot of paired material; i.e., one double foot is equal to one foot of positive material plus one foot of negative material (usually used in determining thermocouple wire loop resistance)
Drain Wire In a cable, the uninsulated wire in intimate contact with a shield to provide for easier termination of such a shield to a ground point
Drawing In wire manufacturing, pulling the metal through a die or series of dies to reduce diameter to a specific size
Duct An underground or overhead tube for carrying electrical conductors
Duplex Insulated In the thermocouple industry, a combination of dissimilar metal conductors of a thermocouple or thermocouple extension wire
