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. Purchase a printed copy here.

Field Fencing

Usually made in galvanized steel wire, this product can also be made in aluminum or aluminum alloy. See Fencing Wire.

Field Range Speed Regulator

A typical speed regulator for a DC drive to control the speed of the DC motor over an extended speed range. It is obtained by weakening the field of the motor as well as varying the armature voltage.

Field Strength

The strength of an electromagnetic field. This measurement may be of either the electric component of the field, with units of V/m, or the magnetic component, with units of A/m2.

Field Wire

A term defining a light, small wire type usually produced in long lengths for use in military field communications.

Field, Electrostatic

The region near a charged object.

Figure 8 Cable

An aerial cable configuration in which the conductors and the strand that supports the cable are integrally jacketed. A cross-section of the finished cable approximates the figure eight.

Filament Wire

Tungsten wires are commonly used in lamps for general lighting service. These fine wires must not be out of round by more than 1 percent, which requires extreme accuracy from the diamond dies used to draw the wire.

Filled Cable

A telephone cable construction in which the cable core is filled with a material that will prevent moisture from entering or passing through.

Filled Core Annular Conductor

A conductor composed of a plurality of conducting elements disposed around a non-conducting supporting material that substantially fills the remaining space.

Filled Tape

Fabric tape which has been thoroughly filled with a rubber or synthetic compound, but not necessarily finished on either side with this compound.

Filler

1) A material used in multi-conductor cables to occupy large interstices formed by the assembled conductors. 2) A substance, often inert, added to a compound to improve properties and/or decrease cost.

Filler Rod

A rod of metal that is melted to provide added metal in arc welding, in­dependently of the electrode.

Filler Wire

Filler metal in the form of a coil of wire that is used to fill the joint in welding processes such as oxy-acetylene and tungsten inert gas arc welding. This term generally refers to filler wire fed in­dependently of the heat source, as distinct from processes where some or all of the metal to fill the joint is obtained by the melting of the electrode itself. Also known as Welding Wire.

Filler Wires

Small auxiliary wires in a strand for spacing and positioning other wires. Also, an alternative name for weft wires in wire mesh.

Filler, Cable

Materials used to fill voids and spaces in a cable construction, normally to give a smooth outer configuration, although it may also serve as flame retardants, etc.

Fillet

A term used when material is used to join two surfaces. It could be a concave junction of two (usually perpendicular) surfaces.

Film

Term used to describe the residual lubricants or rustproofing oil left on a wire surface after processing.

Film Bonded

Cables where bonding is accomplished by solvent-bonding or adhesive bonding wire, cable or spacer to a film to form a cable. See Bonded Cables.

Film Build

The amount of insulating film accumulation on magnet wire as a material that is applied in multiple layers. Film build is defined as a total addition to the bare dimension.

Filter

1) A selective network that allows desired components to pass while suppressing others. 2) A porous substance used to remove suspended impurities or solids from liquid or gas.
