Alpha Wire www.alphawire.com 1-800-52 ALPHA Specifications subject to change. For complete specifications and availability, visit www.alphawire.com. 570 filled cable A telephone cable construction in which the cable core is filled with a material that will prevent moisture from entering or passing through the cable. filler (1) A material used in multiconductor cables to occupy large interstices formed by the assembled conductors. (2) An inert substance added to a compound to improve properties or decrease cost. film A thin plastic sheet. FIT Alpha Wire registered trademark for shrinkable tubing and wire management products. flame resistance The ability of a material not to propagate flame once the flame source is removed. flammability The measure of the material's ability to support combustion. flat cable Multiconductor cable arranged in a parallel type configuration manufactured with controlled tolerance spacing. flat conductor A wire having a rectangular cross section as opposed to round or square conductors. flat conductor cable A cable with several flat conductors. FLC Fluorocopolymer insulating and/or jacketing compounds. flex life The measurement of the ability of a conductor or cable to withstand repeated bending. flexibility That quality of a cable or cable component which allows for bending under the influence of outside force, as opposed to limpness which is bending due to the cable's own weight. foam polyethylene See cellular polyethylene. foamed plastics Insulations having a cellular structure. FPE Foam polyethylene. FPP Foam polypropylene. frequency Number of times an alternating current reverses itself in one second. Express in Hertz (hz), which is one cycle per second. gang strip Simultaneous stripping all conductors in a flat or ribbon cable. Gauge A term used to denote the physical size of a wire. Giga- A numerical prefix denoting one billion (10 9 ). gigahertz (GHz) A unit of frequency equal to one billion hertz. ground A conducting connection between an electrical circuit and the earth or other large conducting body to serve as an earth thus making a complete electrical circuit. ground fault A failure of transmission involving insulation- to-shield or insulation-to- ground wire. halogen Elements such as fluorine, chlorine, bromine, and iodine that are highly reactive and can be harmful to people and animals. hard-drawn copper wire Copper wire that has not been annealed after drawing. harmonized Products meeting requirements of CENELEC for use in European Economic Community. harness An arrangement of wires and cables, usually with many breakouts, which have been tied together or pulled into a rubber or plastic sheath, used to interconnect electric circuits. hash mark stripe A non- continuous helical stripe applied to a conductor for identification. heat distortion Distortion or flow of a material or configuration due to application of heat. heat endurance The time of heat aging that a material can withstand before failing a specific physical test. heat shock A test to determine stability of a material by sudden exposure to a high temperature for a short period of time. helical stripe A continuous, colored, spiral stripe applied to a conductor for circuit identification. henry (H) The unit of inductance. hertz (Hz) The unit of frequency, expressing cycles per second. high voltage Generally, a wire or cable with an operating voltage of over 600 volts. hi-pot A test designed to determine the highest voltage that can be applied to a conductor without electrically breaking down the insulation. hook-up wire A single insulated conductor used for low current, low voltage (usually under 1000 volts) applications within enclosed electronic equipment. hygroscopic Readily absorbing and retaining moisture.
