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.

Cable Eccentricity Gauge

An electronically operated device for continuously indicating the degree of eccentricity of the conductor relative to the surrounding dielectric in extruded wires and cables. A non-destructive test used to control production and for inspection on the final product.

Cable Electrical Characteristics

The four most important characteristics in an electronic cable are impedance, attenuation, shielding and capacitance. See individual listings.

Cable Festoon

A cable draped in accordion fashion from sliding or rolling hangers, usually used to feed moving equipment such as bridge cranes.

Cable Filler

The material used in multiple-conductor cables to occupy the interstices formed by the assembly of the insulated conductors, thus forming a cable core of the desired shape (usually circular).

Cable Guards

Rectangular pieces of fiberglass laminated epoxy (155°C) used to protect delicate cable harness and connectors.

Cable Jacket

See Sheath.

Cable Pullers

A tool for pulling through a conduit. Also, firms that fabricate cable assemblies by pulling the conductors through a plastic, rubber or neoprene tube.

Cable Rack

The vertical or horizontal open support (usually made of aluminum or steel) that is attached to a ceiling or wall.

Cable Shaft

See Vertical Riser.

Cable Sheath

The outermost covering of a cable providing overall protection.

Cable Spinning Machine

Used in the aerial suspension of communication and power cables to bind the cable into close contact with the supporting wire.

Cable Spreading Room

A room adjacent to a control room to facilitate routing of cables in trays away from the control panels.

Cable Terminal

A device that seals the end of a cable and provides insulated egress for the conductors. In power work, also known as a “pothead” or “end bell.”

Cable Testing

A range of tests that are used to evaluate the characteristic of a cable to standards from bodies such as the National Bureau of Standards and ASTM.

Cable Ties

Belt-like plastic strip device that loops around bundles of cables or insulated wires to hold them together (and sometimes to anchor them to an electronic cabinet, a wall or another assembly).

Cable Tray

A rigid structural system used to support cables and raceways. Types of cable trays include ladder, ventilated trough, ventilated channel and solid bottom. Often used for telecommunications.

Cable Vulcanizer

Compression molding machine used to repair cable jacketing that has had a part removed for splicing, for adding connectors or other devices or for replacing damaged sections.

Cable, Aerial

An assembly of one or more conductors and a supporting messenger.

Cable, Armored

A cable having armor. See Armor

Cable, Belted

A multiconductor cable having a layer of insulation over the assembled insulated conductors.
