Balanced Circuit.
A 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.
Balium. A device for matching an unbalanced
coaxial transmission line to a balanced two-wire system.
Band Marking. A continuous circumferential
band applied to a conductor at regular intervals for identification.
Band Width. The frequency range of transmitted
electrical signals, expressed in Hertz.
Bare Conductor. A conductor having no
covering. A conductor with no coating or cladding on the
copper.
BCF. Abbreviation for billion conductor
feet. A quantity derived by multiplying the number of
conductors in a cable by the amount of the cable. Usually
used to indicate plant capacity or an annual requirement.
Binder. A spirally served tape or thread
used for holding assembled cable components in place awaiting
subsequent manufacturing operations.
Bond. The attachment at an interface
between an adhesive and an adherent or between materials
attached together by adhesive.
Bond Strength. Amount of adhesion between
surfaces, e.g., in bonded ribbon cable.
Booster. A device inserted into a line
(or cable) to increase the voltage.
Boot. A protective covering over any
portion of a cable or conductor in addition to its jacket
or insulation.
Braid. A fibrous or metallic group of
filaments interwoven in cylindrical form to form a covering
over one or more wires. Multi/Cable has a large braiding
dept. capable of applying stainless steel, copper, silver,
fiberglass and more.
Braid Angle. The smaller of the two angles
formed by the shielding strand and the axis of the cable
being shielded.
Braid Carrier. A spool or bobbin on a
braider which holds on groups or strands or filaments
consisting of a specific number of ends. The carrier revolves
during braiding operations.
Braid Ends. The 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.
Brazing. The 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 the insulation.
Breakdown of Insulation. Failure 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. Multi/Cable products
are tested throughout the production process for insulation
breakdown.
Breakdown Voltage. The voltage at which
the insulation between two conductors breaks down.
Breakout. The point at which a conductor
or group of conductors breaks out from a multiconductor
cable to complete circuits at various points along the
main cable.
British Standard Wire Gauge. A modification
of the Birmingham Wire Gauge and the legal standard of
Great Britain for all wires. Also known as Standard Wire
Gauge (SWG), New British Standard (NBS), English Legal
Standard and Imperial Wire Guide.
B. & S. Abbreviation for "Brown & Sharpe
Wire Gauge: - same as American Wire Gauge.
Building Wire. Wire used for light and
power, 600 volts or less, usually not exposed to outdoor
environment.
Bunch Stranding. A group of wires of
the same diameter twisted together without a predetermined
pattern.
Buried Cable. A cable installed directly
in the earth without us of underground conduit. Also called
"direct burial cable." All Multi/Cable products can be
made suitable for direct burial.
Bus. Wire used to connect two terminals
inside of an electrical unit.
Butt. Joining of two conductors end-to
end, with no overlap and with the axes in line.
Butt Splice. A splice wherein two wires
from opposite ends butt against each other, or against
a stop, in the center of a splice.
Butt Wrap. Tape wrapped around an object
or conductor in a edge-to-edge condition.
