Glossary
AWG
American Wire Gage. A standard used or specify the physical size of a solid or stranded conductor primarily used in the United States. Originally called the Brown and Sharpe Gage.
Bare Conductor
A conductor having no nonmetallic covering.
Breaking Strength
The maximum load that a ·conductor attains when tested in tension to rupture.
Bunch/Stranded Conductor
A conductor composed of wires twisted together with a given length and direction of lay in such a manner that the respective wires at successive cross sections along the length of the conductor do not necessarily form symmetrical geometric pattern, nor necessarily occupy the same positions relative to each other.
Coated Wire
Wire comprised of a given metal covered with a relatively thin application of a different metal.
Concentric-Lay Conductor
Conductor constructed with a central core surrounded by one or more layers of helically laid wires. Several types are as follows
True Concentric Conductor
Conductor constructed with a round central core surrounded by one or more layers of helically laid round wires. The direction of lay is reversed in successive layers, and generally with an increase in length of lay for successive layers.
Unilay Conductor
Conductor constructed with a central core surrounded by more than one layer of helically laid wires, all layers having a common length and direction of lay.
Rope Construction
Conductor composed of cabled members of any of the above stranded constructions. Closing of the Rope may be True Concentric, Equilay, or Unidirectional.
Conductor
A wire or combination of wires not insulated from one another, suitable for carrying an electric current.
Elongation
A measure of a material’s ability to stretch or elongate prior to fracture. It is expressed as a percentage (increase in length) over a specified gage length (typically 10 inches for wire).
Gage (or Gauge)
A term used to designate the physical size of a wire or strand. Some definitions specify "Gage" as a size designation and "Gauge" as a measuring device (such as pressure gauge). These terms are often used interchangeably.
Lay Direction
The helical direction of the strands or members in any layer of a stranded construction. The two lay directions are usually denoted as "S" (left hand lay) or "Z" (right hand lay).
Lay Factor
The ratio of the lay length to the external diameter of the corresponding layer of wires or members in the stranded conductor.
Lay Length {length of lay)
The axial length for one revolution of a strand or member in any layer of a stranded or rope stranded construction.
Lay
One turn of the helix of a wire or member of a stranded conductor. See also direction of lay and length of lay.
Member
A group of wires stranded together for combination with other stranded groups into a multiple-membered conductor.
Mil
Unit of measure equal to 1/1000 of an inch.
Percent Conductivity
The ratio of the resistivity of the International Annealed Copper Standard (lACS) at 20°C to the resistivity of a material at 20°C, expressed in percent.
Plating Percentage
see Volume Percentage of Plating and Weight Percentage of Plating.
Plating Thickness
The measured thickness of the plated coating on a wire strand. Measurements are usually in micro-inches (millionths of an inch) or microns (millionths of a meter).
Resistance
The scaled property of an electric circuit or of any body that may be used as part of an electric circuit which determines for a given current the rate at which electric energy is converted into heat or radiant energy and which has a value such that the product of the resistance and the square of the current gives the rate of conversion of energy.
Resistivity
The electrical resistance of a body of unit length, and unit cross-sectional area or unit weight.
Soft Wire
Wire that has been drawn or rolled to final size and then heated to remove the effects of cold working.
Stranding Factor
The increase in weight and electrical resistance of a conductor due to the lay length of the strands or members.
Stranded Conductor
A conductor composed of a group of wires, usually twisted, or any combination of such groups of wires.
Temperature Coefficient of Resistance
The change in a material's electrical resistance (resistivity) due to a change of one degree in temperature. It is expressed in units per °C (or units per °F).
Tensile Strength
The maximum longitudinal tensile stress that may be applied or a material without fracturing or rupturing, calculated or a reference unit (lbs/in², kg/mm², etc.) by dividing the breaking load by the cross-sectional area.
Tubular Strander
A type of twisting machine where the payoffs are located inside the tube and the rake-up is external.
Weight per Unit Length
A method of specifying the weight of conductor or wire using a standard length. Common lengths of 1,000 feet or 1,000 meters are used, however other lengths may also be specified.
