| A.C. Resistance |
The total resistance offered by a device in an alternating current circuit due to inductive and capacitive effects, as well as the direct current resistance |
| Abrasion Resistance |
Ability of a wire, cable or material to resist surface wear |
| Accelerated Aging |
A test in which voltage, temperature, and other factors are increased above normal operating values to obtain observable deterioration in a relatively short period of time. The plotted results give expected service life under normal conditions. |
| Accelerated Life Test |
A test in which certain factors such as voltage, temperature, etc., to which a cable is subjected are increased in magnitude above normal operating values to obtain observable deterioration in a reasonable period of time |
| Accelerator |
A chemical additive which hastens a chemical reaction under specific conditions |
| Activator |
A chemical additive used to initiate the chemical reaction in a specific chemical mixture |
| Active Current |
In an alternating current, the component in phase with the voltage; the working component as distinguished from the idle or wattless component |
| Active Pressure |
In an A.C. circuit, the pressure which produces a current, as distinguished from the voltage impressed upon the circuit |
| Adhesion |
The state in which two surfaces are held together by interfacial forces which, may be chemical or mechanical in nature |
| Admittance |
The measure of the ease with which an alternating current flows in a circuit; the reciprocal of impedance |
| Aerial Cable |
A cable suspended in the air, on a pole or other overhead structure |
| Aging |
The irreversible change in properties or appearance of a material with time and specific conditions (usually accelerated representations of environmental states, such as high temperature, oxygen or other various conditions or media) |
| Air Core Cable |
A telephone cable in which the interstices in the cable core are not filled with a moisture barrier |
| Air Spaced Coaxial Cable |
A cable where air is the essential dielectric material; a spirally wound synthetic filament or spacer may be used to center the conductor |
| Alloy |
A metal formed by combining two or more different metals to obtain desirable properties |
| Alpeth |
An aerial telephone cable having an aluminum shield |
| ALS |
A type of cable consisting of insulated conductors enclosed in a continuous closely fitting aluminum tube |
| Alternating Current (AC) |
Electric current that continually reverses its direction; expressed in hertz or Hz (cycles per second) |
| Alternating Voltage |
The voltage developed across a resistance or impedance through which alternating currents are flowing |
| Aluminum (AI) |
A conductor that has similar properties to copper, used only in very specific applications |
