GLOSSARY

GLOSSARY

CSA

Canadian Standards Association. Similar to UL in the United States.

Cu

Abbreviation for Copper in accordance with the Periodic Table of Elements.

CURRENT

The rate of transfer of electricity. The unit of current is the ampere, rate of one coulomb per

second.

DC

Direct current. Electrical current whose electrons flow in one direction only. It may be constant or

pulsating as long as their movement is in the same direction.

DIAMETER

A straight line passing through the center of a circle or sphere and meeting the circumference or

surface at each end.

DIE

A metal block that is used for forming materials.

DIE CAST

A metal casting process that is characterized by forcing molten metal under high pressure into a

mold cavity. The mold cavity is created using two hardened steel dies which have been machined

into shape and work similarly to an injection mold during the process.

DIELECTRIC

An electrical insulator that can be polarized by an applied electric field.

DOT

Department of Transportation.

DRAWING

A technical drawing used to fully and clearly define requirements for engineered items.

DRAWING, WIRE

A metal working process used to reduce the cross-section of a wire by pulling the wire through a

single, or series of drawing dies. Although similar in process, drawing is different from extrusion,

because in drawing the wire is pulled, rather than pushed, through a die.

DUAL EXTRUSION

involves combining two or more extruders to produce wire with two or more colors.

ELASTOMER

Any material that will return to its original dimensions after being stretched or distorted.

ELECTRO-TINNED

To plate or coat (a base metal) with tin by electrolysis.

ELECTROLYSIS

Is a process by which electrical energy is used to produce a chemical change.

EPDM

(Ethylene Propylene Diene Monomer (M-class) rubber) A type of synthetic rubber.

EXTRUSION

The act or process of shaping by forcing through a die.

°F

Common abbreviation for Fahrenheit.

FERROUS

Composed of and/or containing iron. A ferrous metal exhibits magnetic characteristics.

FILLER

Something added to augment weight or size or fill space.

FLAME RETARDANT

Chemicals used in thermoplastics, thermosets, textiles and coatings that inhibit or resist

the spread of fire.

FLANGE

Disc shaped collar on the end of a spool or reel to prevent wire from sliding off barrel.

FLEXIBILITY

The distance of motion.

FLEXIBLE

Capable of being bent, usually without breaking. Susceptible of modification or adaptation. Pliable.

GAUGE

A standard of measure or measurement.

GOLD-PLATED

A base metal coated with gold through an electroplating process.

GPT

General Purpose Thermoplastic.

GRAVITY CAST

A manufacturing process utilizing the force of gravity instead of high pressure to fill a permanent

mold, or die, with molten material. The molten material is then allowed to solidify within that

mold, and is then ejected or broken out to make a fabricated part.

GROUND

A voltage reference point that is the same as earth or chassis ground.

GXL

General purpose Cross-linked polyethylene insulated wire. Intended for use in engine

compartments where higher heat resistance is required.

ID

Inside Diameter.

INSULATION

A material having good dielectric properties which is used to separate close electrical components,

such as cable conductors and circuit components.

ISO

International Organization for Standardization.

JACKET

Pertaining to wire and cable, the outer sheath which protects against he environment and may also

provide additional insulation.

LAY

The length measured along the axis of a wire or cable required for a single strand (in stranded

wire) or conductor (in cable) to make one complete turn about the axis of the conductor or cable.

LAY DIRECTION

The twist in the cables as indicated by the top strands while looking along the axis of the cable

away from the observer. Described as right-hand or left hand.

LME

London Metal Exchange.

MC

Master Carton.

MIL

Military specification.

MTW

Machine Tool Wire.

NAFTA

North American Free Trade Agreement.

NATM

National Association of Trailer Manufacturers

NATIONAL ELECTRICAL CODE

A U.S. consensus standard published by the National Fire Protection Association (NFPA) and

(NEC)

incorporated in OSHA regulations.

NEGATIVE

A polarity of electrical charge.

NEUTRALIZE

A chemical reaction in which an acid and a base react to form a salt. Water is frequently, but not

necessarily, produced as well.

NMMA

National Marine Manufacturers Association.

NM-B

A UL Cable type, non metallic–sheathed cable.
