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.

Hard-Laid Rope

Rope formed from large wires. Also known as coarse laid.

Hardenability

The property that determines the depth and distribution of hardness of a metal induced by quenching. Increased hardenability results in deeper hardening, or the achievement of a given hardness with a less rapid quenching rate. The ability of a metal to react to a hardening heat treatment as measured by surface hardness and the depth of hardening below the surface.

Hardening

Increasing the hardness of steel by heat treatment. The steel is heated to a suitable austenitizing temperature, holding at that temperature for a sufficient time to affect the desired solution of carbon and other alloying elements, then quenching in a suitable medium, such as water, oil, air, polymer or molten salts to form martensite.

Hardness

Resistance of metal to deformation under a static load, usually by indentation. May also refer to stiffness or temper, or to resistance to scratching, abrasion or cutting. Indentation hardness may be measured by various hardness tests, such as the Brinell, Rockwell and Vickers Tests.

Hardness Tests

See Brinell, Rockwell and Diamond Pyramid (Vickers) Hardness Tests.

Harmonic

An oscillation whose frequency is an integral multiple of the fundamental frequency.

Harness

An arrangement of wires and cables, usually with many breakouts, which have been tied together or pulled into a rubber or plastic sheath, used to interconnect an electric circuit.

Hash Mark Stripe

A non-continuous helical stripe applied to a conductor for identification. See Band Marking, Color Code and/or Helical Stripe.

Hat

A special pallet for transporting long rubber strips or coils of wire; the pallets look like a hat.

Hawser Wire

This is patented medium carbon steel wire hard drawn to sizes and tensiles dependent on the particular type and diameter of the hawser (a wire rope). It is usually galvanized, used for towing or mooring vessels. The bulk of this material is galvanized after drawing.

Hay Bailing Wire

A mild steel wire that is fully annealed. It is cut into lengths after annealing, and the ends looped by twisting. Also known as Hay Band Wire.

Hay Band Wire

See Hay Bailing Wire.

Hazlett Continuous Casting

One of several systems used to continuously cast copper or aluminum bars. Developed by Hazlett Strip-Casting Corporation.

HB

Designation for Brinell hardness value.

HC

Designation for two or more conductor heater cords, with asbestos and rubber insulation with cotton braid over each conductor. The cords are twisted, with no overall covering.

HDPE

Designation for High Density Polyethylene.

Head

The end section of an extruder in which the melt is transferred to the cable.

Head Lining Wire

The wire used to support the lining inside the roofs of cars. Either low carbon bright hard drawn that is often rolled into a cloverleaf or top hat section, or a high carbon wire sufficiently ductile to withstand the cold forming. Also known as lintel wire.

Head Set Cord

A very flexible multi-conductor cord used for communication equipment. Usually made with Buna insulation, rubber or neoprene jacket; sometimes the outer jacket is a cotton braid. The conductor may be bare copper or cadmium bronze.

Heading

1) When annealing with the molten lead bath, this refers to similar material through which wire is passed after lead annealing if no coating process is to follow. 2) The same procedure is used after galvanizing to remove excess zinc. 3) The process for forming the heads of fasteners. See Cold Heading.
