ACR - Designation for cable with corona resisting insulation.
ACRS - Aluminum conductor, steel reinforced. Aluminum wires stranded around a steel core. Usually used for high voltage cross-country transmission lines.
ADAPTER - a) Device used for joining two fiber optic connectors together. b) A device for connecting two parts (of different diameters) of an apparatus.
ADHESIESIESIVE - Usually a synthetic material which, when applied to tapes, potting operations, etc., permits materials to be bonded together.
ADMITTANCE - Symbol
Y. The reciprocal of impedance.Given by the formula:
Y = G + iB
where
G is the conductance,
B the susceptance, and
i equals
. Since impedance,
Z, is given by:
Z = R + iX
AEC - Atomic Energy Commission. The government agency which oversees all atomic energy projects.
AERIAL CABLE - A cable suspended in the air on poles or other overhead structures.
AIEE - Formerly American Institute of Electrical Engineers. Now called the Institute of Electrical and Electronic Engineers (IEEE).
AIR SPACED COAX - A coaxial cable in which air is basically the dielectric material. The conductor may be centered by means of a spirally wound synthetic filament, beads, or braided filaments. This construction
is also referred to as an air dielectric.
AIRCRAFT IGNITION CABLE - A high tension cable designed for use in the ignition systems of internal combustion aircraft engines.
AIRCRAFT WIRE - An electrical wire primarily designed for the extreme conditions (temperature, altitude, solvents, fuels, etc.) of airborne equipment.
AL - Abbreviation for aluminum.
