Glossary

Braid Angle: The angle between the axis of the cable and axis of any

one member or strand of the braid (also known as angle of advance).It

is further the smaller of the two angles formed by the carrier and the

longitudinal axis of the braid.

Braid Carrier: The bobbin on a braiding machine which holds one

group of strands or ﬁlaments consisting of a speciﬁc number of ends.

The carrier revolves during the braiding operation

Braid Ends: The strands used to make up one carrier.The strands are

wound side by side on the carrier bobbin and lay parallel in the ﬁnished

braid.

Breakdown: A disruptive electrical discharge through the insulation.

Breakdown Voltage: The voltage at which the insulation between

two conductors will break down.

Breakout: The point at which a conductor or conductors break out

from a multi-conductor cable to complete circuits at various points

along the main cable.The remaining conductors continue on within the

jacket.

B & S: Brown & Sharpe Gage, a wire diameter standard.Same as AWG.

Building Wire: Insulated wires used in buildings for light and power.

600 V or less.Usually not exposed to outdoor environment.

Bunched Stranding: Terms applied to group of strands twisted

together in a random manner in the same direction in one operation

without regard to geometric arrangements of speciﬁc strands.

Bus: A common point for electrical circuits to return.

Bus Bar: A heavy copper (or other metal such as aluminum) strip or

bar used inside switchboards, power plants, and main panels to carry

heavy currents.

Bus Wire: Wire used to connect two terminals inside an electrical unit.

Butt Joint: Joining of two conductors end-to-end, with no overlap and

with their axes in line.

"C" (cured) Stage (of resin): The condition of a resin polymer when it

is in the solid state, with high molecular weight, being insoluble and

infusible.

Cable: Either a stranded conductor with or without insulation and

other covering (single-conductor cable), or a combination of

conductors insulated from one another (multiple-conductor cable).

Cable Assembly: A cable with connectors on one or both ends.

Cable Core: The portion of an insulated cable lying under the

protective covering or coverings.In coaxial cables, the center conductor

and dielectric.

Cable Core Binder: A wrapping of tapes or cords around the several

conductors of a multiple-conductor cable used to hold them together.

Usually supplemented by an outer covering of braid, jacket, or sheath.

Cable Filler: The material used in multiple-conductor cables to occupy

the interstices formed by the assembly of the insulated conductors,

thus forming a cable core of the desired shape (usually circular).

Cable Sheath: The protective covering applied to cables.

Cabling: Twisting together two or more insulated conductors by

machine to form a cable.This also is a term loosely applied to bundling

of wires together such as in the forming of wire harnesses.

Cable Factor: Used in a formula for calculating the overall diameter of

cables:D=fd where D=cable diameter, f=factor, and d=diameter of

one conductor.

Capacitance: That property of a system of conductors and dielectrics

which permits the storage of electricity when potential difference

exists between the conductors.Its value is expressed as the ratio of a

quantity of electricity to a potential difference.A capacitance value is

always positive.

Capacitive Coupling: Electrical interaction between two conductors

caused by the mutual capacitance between them.

Carrier: The basic woven element of a braid consisting of one or more

ends (strands) which creates the interlaced effect.

Cellular Insulation: Material in foamed form with the cells either

closed or open (interconnected).

Characteristic Impedance (Z0): The impedance of a circuit that,

when connected to the output terminals of a uniform transmission line

(such as a coaxial cable) of arbitrary length, causes the line to appear

inﬁnitely long.A uniform line terminated in its characteristic

impedance will have no standing waves, no reﬂections from the end,

and a constant ratio of voltage to current at a given frequency at every

point on the line.

Cigarette Wrap: Tape insulation wrapped longitudinally instead of

spirally over a conductor.

Circuit: A complete path over which electrons can ﬂow from the

negative terminals of a voltage source through parts and wires to the

positive terminals of the same voltage source.

Circular Mil: A unit of area equal to the area of a circle whose

diameter is 1 mil (0.001 inch); equal to (square mil x .7854).Used

chieﬂy in specifying cross-sectional areas of round conductors.

Cladding: A method of applying a layer of metal over another metal

whereby the junction of the two metals is continuously welded.Clad

wires have a thicker layer of the covering metal than plated wires.

Closed Cell: Foamed or cellular material with cells which are not

interconnected.

Coating: Plating the surface of a conductor to prevent corrosion and

facilitate soldering.In wire terminology,“coated”is often used

interchangeably with“plated.”Term can also apply to an insulating

coating.

Coaxial Cable: A cable consisting of two cylindrical conductors with a

common axis, one inside the other.The two conductors are separated

by a dielectric.The outer conductor, normally at ground-potential, acts

as a return path for current ﬂowing through the center conductor and

prevents energy radiation from the cable.The outer conductor, or shield,

is also used to prevent external radiation from affecting the current

ﬂowing in the inner conductor.The outer shield or conductor can

consist of braided strands of round or ﬂat wire, or a solid metal tube.

Coil Effect: The inductive effect caused by a spiral-wrapped shield;

more pronounced at higher frequency.
