NOMINAL Name or identifying value of a measurable property by which a conductor or component or property of a conductor is identified, and to which tolerances are applied. NON-FERROUS Indicates metals other than iron and alloys that do not contain an appreciable amount of iron. OD Outside diameter. OE Original Equipment. OEM Original Equipment Manufacturer. OHM The electrical unit of resistance. OSHA U.S. Occupational Safety and Health Administration. Pb Abbreviation for Lead in accordance with the Periodic Table of Elements. PIES Product Information Exchange Standard. PLASTICIZER A chemical agent added to plastics to make them softer and more pliable. POLARITY Present in every electrical circuit. Electrons flow from the negative pole to the positive pole. In a direct current (DC) circuit, one pole is always negative, the other pole is always positive and the electrons flow in one direction only. In an alternating current (AC) circuit the two poles alternate between negative and positive and the direction of the electron flow continually reverses. POLYETHYLENE (PE) A thermoplastic material having excellent electrical and physical properties. POLYMER A substance made of many repeating chemical units or molecules. The term polymer is often used in place ov plastic, rubber, or elastomer. POLYPROPYLENE (PPE) A thermoplastic similar to polyethylene but stiffer and having a higher softening point (temperature). POSITIVE A polarity of electrical charge. POLYVINYL CHLORIDE (PVC) A general-purpose thermoplastic used for low voltage wire and cable insulation, and for jackets. REEL DRUM DIAMETER Diameter of the drum (or hub) of the reel. REEL FLANGE DIAMETER Diameter of the reel flanges. (REEL HEIGHT) REEL TRAVERSE Width of space between reel flanges. REEL WIDTH Overall width of reel. RESISTANT Impervious to the action of corrosive substances. RCCC Regular Common Carrier Conference. ROOT MEAN SQUARE (RMS) The effective value of an alternating current or voltage. RoHS Restriction of Hazardous Substances. ROPE LAY CONDUCTOR A conductor composed of a central core surrounded bo one or more layers of helically laid groups of wires used in portable cables. SAE Society of Automotive Engineers. SAE J378 Marine propulsion system wiring. SAE J1127 Low voltage battery cable. SAE J1128 Low voltage primary cable. SAE J1494 Battery booster cables. SAE J2394 Seven conductor cable for ABS power - truck and bus. SGT Starter or Ground, general purpose, thermoplastic insulated cable. SGX Starter or Ground, general purpose, Cross-linked polyethylene insulated cable. SINTERED METAL Metal created from powder. Advantages include very high levels of purity and controlled, uniformed porosity. SLEEVING An extruded tube. SOLDER A fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s). SPECIFIC GRAVITY The ratio of the density (mass per unit volume) of a material to that of water. SPLICE The physical connection of two or more conductors to provide electrical continuity. STANDARD Something established by authority, custom, or general consent as a model or example. Something set up and established by authority as a rule for the measure of quantity, weight, extent, value, or quality. STRANDED CONDUCTOR A conductor composed of a group of wires, usually twisted, or of any combination of such groups of wire. SXL Special purpose, Cross-linked polyethylene insulated wire. Used in engine compartments where higher heat resistance is required. TEMPERATURE RATING A measure of the highest (or occasionally lowest) temperature at which it is safe to use a product for a particular purpose. For example, temperature ratings are often quoted for electrical insulators, specifying the maximum temperature at which they provide adequate protection against electrical breakdown. TEMPERED STEEL A heat treatment technique that is done to "toughen" the metal by transforming brittle martensite or bainite into a combination of ferrite and cementite or sometimes Tempered martensite. Tempering is accomplished by a controlled reheating of the work piece to a temperature below its lower critical temperature. TENSILE STRENGTH The maximum load per unit of original cross-sectional area that a conductor attains when tested in tension to rupture. GLOSSARY 112 PAGES 110 THRU 113 GLOSSARY
