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.

Fused Coating

A metallic coating (usually tin or solder alloy) that has been melted and solidified, forming a metallurgical bond to the base metal.

Fused Conductors

Individual strands of heavy tinned copper wire stranded together and then bonded together by induction heating.

Fused Spiral Tape

A PTFE insulated hookup wire. The spiral-wrapped conductor is passed through a sintering oven where overlaps are fused together.

Fusible Link, Cable

Cable that provides the features of a fuse. The conductor overheats and burns away when fed more current than that rated for by the cable.

Fusing

Fusing, or wire fusing, describes the termination of a magnet wire by application of heat without prior removal of its film insulation. The insulation is removed during the fusing process. Hot Staking is a specific term used for the fusing of commutators.

FX

Designation for single rubber-insulated Christmas tree wire with outer braid, 125V, 60°C.

FXT

Designation for single plastic-insulated Christmas tree wire, 125V 60°C.

FZCV

Designation for continuous vulcanization process using silicon oil.

G

Designation for rubber-insulated, neoprene jacketed, portable power cable with two to five #8 AWG or larger conductors with ground wires.

G Cable

Designation for a type W or power cable with ground wires. The total CM area of the ground wires is approximately one-half to three-quarters of the CM area of one of the conductors.

G-GC

Designation for a type of G cable containing a ground check wire.

Gadroon Wire

A soft brass, copper or nickel silver wire with a pattern rolled on to it. It is mainly used in the fancy trade for the edging of trays and to cover the edges of mirrors.

Gage

An alternative spelling for gauge.

Gain

The increase of voltage, current or power over a standard or previous reading. Usually expressed in decibels (dB).

Galfan

Hot-dipped coating applied to steel wire that consists of an alloy of zinc, aluminum and mischmetal. It is a trademark of the Galfan Technology Centre, Inc.

Galling

A wire surface defect that results from the disruption of the lubricant layer between metal asperities and the forming die during drawing. The additional friction may cause localized heating, surface roughness, spalling, and the formation of transverse cracks.

Gallium

Element, chemical symbol Ga. This bluish-white metal (silvery-white metal at high purity) can be recovered from bauxite and zinc processing. Used to make semiconductors, laser diodes, light emitting diodes, integrated circuits, photo detectors, solar cells and other optoelectronic devices.

Gallows

Term once used to describe the hoist over the final block of a drawing machine for removing completed coils of wire. Some machines were provided with a traveling hoist enabling in­termediate blocks to be stripped when desired.

Galvanized Wire

See Galvanizing.

Galvanizing

The application of a zinc coating on the surface of steel wire to protect it from corrosion. This can be done by either dipping the wire in a bath of molten zinc or by the electro-deposition of a zinc coat from an aqueous solution of a zinc salt.
