![]() ![]() The radius of curvature that a wire or cable can bend without causing any damaging effects.Ī spirally served tape or thread used for holding assembled cable components in place awaiting subsequent manufacturing operations.ĭiscrepancy between outgoing and incoming bits transmitted between date equipment.Ī cylinder or slightly tapered barrel, with or without flanges, for holding slubbings, rovings, or yarns. Expressed in hertz (Hz).Īn electrical conductor with no coating or cladding on the copper. The difference between the upper and lower limits of a given band of frequencies. ![]() The average direction of all yarns in a braided fabric.Ī continuous circumferential band applied to a conductor at regular intervals for identification. UL or CSA designation for Appliance Wiring Material. The lower the AWG number, the larger the diameter. The standard system used for designating wire diameter. Those frequencies audible to the human ear, generally considered to be in the range of 32 to 16,000 hertz (Hz).Ībbreviation for American Wire Gauge. In cables, generally expressed in dB per unit length, usually 1,000 ft. The ratio of length to diameter of yarn filament or yarn bundle.Īmerican Society for Testing and Materials. The American Society of Mechanical Engineers. Former name of ANSI.Īmerican Standard Code for Information Interchange. Placed over the jacket sheath.Ī cable having a metallic covering for protection against mechanical damage.Ībbreviation for American Standards Association. The size of a conductor cross-section measured in circular mils, spare inches, etc.Ī wrapping of metal, usually steel or aluminum, used for mechanical protection. Annealing copper renders it less brittle.Ībbreviation for American National Standards Institute.Ī substance which prevents or slows down oxidation of material exposed to heat. The relief of mechanical stress through heat and gradual cooling. Representation of data by continuously variable quantities. One ampere is the current flowing throughout one ohm of resistance at one volt potential. The maximum current an insulated wire or cable can safely carry without exceeding either the insulation or jacket material limitations. One ampere is the current flowing through one ohm of resistance at one volt potential. The temperature of a medium surrounding an object.Ī standard system for designating wire diameter. The minimum gap of air between two conducting surfaces permissible at given voltages.Ī metal formed by combining two or more different metals to obtain desirable properties.Įlectric current that continually reverses its direction. The irreversible change in properties or appearance of a material with time and under specific conditions (usually accelerated representations of environmental states, such as high temperature, oxygen or other various conditions or media). The state in which interfacial forces that may be chemical or mechanical in nature hold tow surfaces together.Ī cable suspended in the air on poles or other overhead structure. circuit the pressure that products a current as distinguished from the voltage impressed upon the circuit. In an alternating current, a component in phase with the voltage the working component as distinguished from the idle or watt less component. The plotted results give expected service life under normal conditions. Tests where voltage, temperature, etc., are increased above normal operating conditions to obtain observable deterioration in a relatively short period of time. 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.Ībility of a wire, cable or material to resist surface wear.
