GLOSSARY OF TERMS
ABRASION RESISTANCE       Ability of a wire, cable or material to resist sur face wear.
ALLOY       A metal formed by combining two or more different metals to obtain desirable proper ties.
ALTERNATING CURRENT (AC)       Electric current that continually reverses its direction. It is expressed in cycles per second
(Her tz or Hz).
AMBIENT TEMPERATURE       The temperature of the medium surrounding an object.
AMPACITY       The maximum current an insulated wire or cable can safely carr y without exceeding either the
insulation or jacket material limitations.
AMPERE       A unit of current; one ampere is the current flowing through one ohm of resistance at one volt
potential.
ANNEAL       To soften and relieve strains of metal by heating to just below melting point then slowly cooling.
Annealing lowers the tensile strength of copper, while improving flex life and flexibility.
ANSI       American National Standards Institute.
ASA       American Standards Association. Former name of ANSI.
ASME       American Society of Mechanical Engineers.
ASTM       American Society for Testing and Materials.
ATTENUATION       Reduction of signal strength during transmission. In cables, generally expressed in dB per unit
length, usually 1000 feet.
AUDIO FREQUENCY       The range of frequencies audible to the human ear. Usually 20-20,000 Hz.
AWG       American Wire Gauge.
AWM UL       designation for appliance wiring material.
BAND WIDTH       The frequency range of transmitted electrical signals, expressed in Her tz.
BARE CONDUCTOR       A conductor having no covering, coating or cladding on the copper.
BEND RADIUS       Radius of cur vature that a cable can bend before the risk of breakage or increased attenua-
tion occurs. To determine bend radius a good rule of thumb is not to exceed ten times the
cable diameter.
BINDER       A spirally ser ved tape or thread used to hold cable components in place.
BOND       The attachment at an inter face between an adhesive and an adherent or between materials
attached by adhesive.
BOND STRENGTH       Amount of adhesion between sur faces, e.g., in bonded ribbon cables.
BRAID       A group of textile or metallic filaments inter woven to form a tubular flexible structure which
may be applied over one or more wires or flattened to form a strap.
BRAID ANGLE       The smaller of the two angles formed by the shielding strand and the axis of the cable
being shielded.
BRAZING       The joining of ends of two wires or groups of wires with a nonferrous filler metal at temperatures
in excess of 800°F / 427° C.
