BRAKE WIRE - Wires used in the manufacture of both home and truck trailers to supply current to the electrical brakes on the equipment.
BRAZING - The joining of the end of two wires, rods, or groups of wires with a nonferrous filler metal at temperatures above 427° C (800° F).
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 a voltage or defects or decay in the insulation.
BREAKDOWN(PUNCTURE) - Adisruptive discharge through the insulation.
BREAKDOWNVOLTAGE - The voltage at which the insulation between two conductors breaks down.
BREAKING STRENGTH - The maximum load that a conductor can withstand when tested in tension to rupture. This force is usually expressed in pounds (lbs) or kilograms (kgs).
BREAKOUT - A breakout is a joint where a conductor or conductors break out from a multi-conductor cable to complete circuits at various points along the main cable. The rest of the conductors continue on within the jacket. The breakout may itself be jacketed and the joint sealed.
BROADBAND - A frequency band that extends over a relatively large range.
BUFFER (TUBE) - Metallic or nonmetallic tube used to protect optical fibers from physical damage, providing mechanical isolation and/or protection.
BUILDING WIRE - Commercial wires used in the building trades such as:Types RR, RH, RL,TW,THW, and THHN wires. General used for light and power, 600 volts or less, usually not exposed to outdoor environment.
BUNA RUBBER - A synthetic rubber used as a replacement for natural rubber.
BUNCH STRANDING - A conductor in which all individual wires are twisted in the same direction without a predetermined pattern.
