The Book of TermsThe WJI Book of Wire & Cable Terms: an interactive experience of learning and sharing
This book, written by industry volunteers and containing more than 5,000 entries, is an asset for newcomers to wire and cable.

At the same time, it also represents an opportunity for industry veterans to give back by either updating or adding to the more than 5,000 entries. This is an honor system process. Entries/updates must be non-commercial, and any deemed not to be so will be removed. Share your expertise as part of this legacy project to help those who will follow.

Soap Rolled Finish

See Kerosene Rolled Finish.

Soaping Out

Formation of insoluble soap that occurs when steel is wet drawn after liming, a combination of free fatty acid and lime.

Soda Dip Finish

See Bichromate Dipped Finish.

Sodium Benzoate

A corrosion inhibitor on nonferrous metals.

Sodium Conductor

An electrical conduc­tor formed by injecting molten sodium under inert gas atmosphere into a tube of sheathing material. The molten sodium solidifies without external cooling and the conductor can then be put through a die to ensure continuous contact between sheathing material and sodium. A central high tensile core can be introduced into the tube and held in position in the center of the tube while the liquid sodium is in­troduced. The sodium should not be exposed to air because of high reactivity.

Sodium Soaps

Lubricants consisting of a mixture of caustic soda or soda ash with a suitable fatty acid.

Sodium Stannate

Used in alkaline tin-plating baths.

Soft Drawn

1) A relative measure of the tensile strength of a conductor. 2) Wire that has been annealed to remove the effects of cold working. 3) Drawn to a low tensile. 4.) Drawn with a reduction of area from the rod or annealed base of about 10 percent

Soft Spot

A defect that usually results in ductile tensile failure produced by non-uniform cooling after hot rolling.

Soft Steel

Carbon steel containing up to about 0.15 percent carbon.

Solder

A metal or metallic alloy used when melted to join metallic surfaces. Usually consists of an alloy of tin and lead where the tin content ranges from about 5 percent to about 100 percent for general uses. Cored solders have a flux, usually a powder in the center of the wire.

Solder Cup

A tubular end of a terminal in which a conductor is inserted prior to being soldered. It is also the hollow cylinder at the rear of a solder contact where a wire is inserted and soldered in place.

Solder Lug

A metal connector to which wire is secured by soldering. Solder lugs are attached to a PC board, termination strip, chassis or electrical component.

Soldereze

A trade name for magnet wire insulated with polyurethane base enamel.

Soldering

Joining metals by fusion of solder.

Solderless Wrap

See Wire Wrapping.

Solenoid

Electric conductor wound as a helix with a small pitch, as in a coil.

Solid Cable

All designs of medium and high voltage paper-insulated power cables except pressurized types.

Solid Conductor

A conductor that consists of a single wire.
