GLOSSARY

PAGES 107 THRU 110

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 volatege battery cable.

SAE J1128

Low volatege 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.
