Term Description
B. & S.Abbreviation for "Brown & Sharpe Wire Gauge" - same as American Wire Gauge
Balanced CircuitA circuit so arranged that the impressed voltages on each conductor of the pair are equal in magnitude but opposite in polarity with respect to ground
Band markingA continuous circumferential band supplied to a conductor at regular intervals for identification
Band WidthThe frequency range of transmitted electrical signals, expressed in Hertz.
Bare conductorA conductor having no covering, coating or cladding
BCFAbbreviation for billion conductor feet. A quantity derived by multiplying the number of conductors in a cable by the amount of cable. Usually used to indicate plant capacity or an annual requirement.
BinderA spirally served tape or thread used for holding assembled cable components in place awaiting subsequent manufacturing operations.
BondThe attachment at an interface between an adhesive and an adherent or between materials attached together by adhesive
Bond StrengthAmount of adhesion between surfaces, e.g., in bonded ribbon cable
BootA protective covering over any portion of a cable or conductor in addition to its jacket or insulation
BraidA fibrous or metallic group of filaments interwoven in cylindrical form to form a covering over one or more wires
Braid AngleThe smaller of the two angles formed by the shielding strand and the axis of the cable being shielded
Braid CarrierA spool or bobbin on a braider which holds one group of strands or filaments consisting of a specific number of ends. The carrier revolves during braiding operations.
Braid EndsThe number of strands used to make up one carrier. The strands are wound side by side on the carrier bobbin and lie parallel in the finished braid.
BrazingThe joining of ends of two wires, rods or groups of wires with a nonferrous filler metal at temperatures above 800F (427C).
Breakdown (Puncture)A disruptive discharge through insulation
Breakdown of InsulationFailure of an insulation resulting in a flow of current through the insulation. It may be caused by the application of too high voltage or by defects or decay.
Breakdown VoltageThe voltage at which the insulation between two conductors breaks down
BreakoutThe point at which a conductor or group of conductors break out from a multi-conductor cable to complete circuits at various points along the main cable
Building WireWire used for light and power, 600 volts or less, usually not exposed to outdoor environment
Bunch StrandingA group of wires of the same diameter twisted together without a predetermined pattern
Burried CableA cable installed directly in the earth without use of underground conduit. Also called "direct burial cable."
