Term used for lighter oils that have a low reading of viscosity. In aluminum wiredrawing, this usually refers to 30 to 60 SSU (1 to 10 centistokes).

Defined by the National Electrical Code as 600V and less. AEIC, ICEA and UL generally define cables rated up to 2kV as low voltage.

Steel wire having a carbon content of up to about 0.25 percent and generally between 0.04 and 0.16 percent, silicon from a trace to about 0.35 percent, and manganese between 0.3 and 0.9 percent. The sulfur and phosphorus contents should not usually be higher than 0.05 and .04 percent, respectively.

A two- or three-conductor cable for outdoor decorative, recreational, or safety lighting applications rated for 150V or less.

Materials used in cables to ensure they produce little or no smoke and no toxic gases during a fire. See Halogen and Halogen-Free.

Insulated wires that will carry low voltage such as in doorbell or chime applications. Small diameter wires are referred to as bell wire and are usually 18 AWG to 20 AWG. Most often the voltage applied does not exceed 24V.

Designation for Low Smoke. See Halogen and Halogen-Free.

Designation for Large Scale Integration.

Any substance that serves as a continuous film that through its presence reduces the friction between two surfaces in contact. Two distinctive forms of lubrication are principally employed in wiredrawing: dry soap powder lubricants and wet lubricants. Lubricants can be further classified into the following categories: rod coatings, dry soap powders (solid lubricants), oil-based liquid lubricants, grease-type lubricants and water-emulsifiable lubricants. It is customary to use rod coatings and dry lubricants to draw coarse ferrous wire. Oil-based and grease-type lubricants are generally used on the single-die drawing of rod and coarse ferrous wire. Water-emulsifiable-type lubricants are generally used to draw nonferrous wire and small diameter steel wire that may be coated with a nonferrous material such as copper. See Coolant.

An inorganic substance, such as lime, borax, silicates or phosphates, with which ferrous wires are coated to facilitate pick-up and retention of lubricant on the wire during drawing. See Bonderizing, Borax and Liming.

The five types of water-emulsified liquid lubricants include soap-fat lubricants, soluble oils, semi-synthetics, synthetics and micro-emulsions. These are primarily used for nonferrous wiredrawing applications. See Lubricant and Coolant.

Term used to evaluate the lubricating characteristics of a coolant as it is performing its function. These cover fatty oils to enhance extreme pressure characteristics, as well as typical barrier lubricating components, which offer resistance to welding and galling. Lubricity is one of the characteristics of a coolant, which allows it to protect machine components and the product from damaging friction.

Surface markings resulting from localized flow that appear on some alloys after light forming. They lie approximately parallel to the direction of maximum shear stress (about 45° to the direction of applied stress), and appear as depressions when forming is in tension and as elevations when forming is in compression.

A termination, usually crimped or soldered to the conductor, with provision for screwing on to the terminal.

The derived SI unit for luminous flux.

The total visible energy that is generated by a source in a given amount of time.

A patented process for the manufacture of aluminum-coated steel wire by hot dipping.

The derived SI unit for illuminance equal to 1 lumen/m2.

Designation for Low Voltage.

1) Designation for meter. 2) Designation for 1,000. 3) Suffix indicating two or more insulated, twisted conductors under an outer, non-metallic covering.
