The Book of Terms

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.

Registration

Alignment of one object relative to another. Also called Register.

Regular Sections

Popular carbon steel structural sections that have a high demand and are frequently scheduled for rolling.

Regulation

Controlling the maximum amount that a power supply output will change as a result of the specified change in line voltage, output load, temperature or time.

Reheating

A thermal operation designed solely to reheat products for follow-up operations such as hot forming, application of coatings and heat-treating. In general, no structural changes are intended.

Reinforced Jacket

A cable jacket with reinforcing fiber between layers.

Reinforced Plastic

Material, such as fiberglass, that for the wire and cable industry can be used for components such as pickling tanks, acid storage and fume extraction equipment.

Reinforced Sheath

The outermost covering of a cable that has a sheath constructed in layers with a reinforcing material, usually a braided or double spiral fiber, molded in place between layers.

Reinforcement

A material used to reinforce, strengthen, or give dimensional stability to another material such as the braid portion of a sheath constructed in layers.

Reinforcement Wire

See Concrete Reinforcement Wire.

Reinforcing Bar

Also known as “concrete reinforcing bar” or “rebar.” A commodity-grade steel used to strengthen concrete in highway and building construction.

Relative Capacitance

The ratio of the material’s capacitance to that of a vacuum of the same configuration will vary with frequency and temperature. Also known as SIC (Specific Inductive Capacitance). An excellent indicator of chemical or physical changes in materials.

Relay

An electrically controlled device that opens and closes electrical contacts to effect the operation of other devices in the same or another electrical circuit.

Relay, Overcurrent

A relay designed to open a circuit when a current in excess of a particular setting flows through the sensor.

Reliability

The probability that a device will function without failure over a specified period or amount of usage.

Reluctance

Property of a magnetic circuit that determines the total magnetic flux in the circuit when a given magnetomotive force is applied.

Remanence

The magnetic induction that remains in a magnetic circuit after the removal of an applied magnetomotive force.

Remote Control Cable

Any cable used to activate and/or power a function or equipment located remotely from the source of control. Shielding is generally required on control cables where there are sensitive electronic components contained in the overall cable construction.

Remote Control Circuit

Circuit designed to provide signals for remote control operations.

Repeatability

The closeness of agreement among repeated measurements of the same variable under the same conditions.

Repeater

A device used in long transmission lines to amplify a degraded signal and increase the system transmission length if needed. It consists of a transmitter and a receiver or transmitter.
