One of the three forms of carbon in nature (the other two are amorphous and diamond). It is one of the softest materials known, is lightweight and has high electrical conductivity. In colloidal form, graphite is being used as a lubricant, and is particularly suitable for hot drawing applications. A disadvan­tage of its use, however, is that dies need cleaning occasionally. It is usually supplied as a colloidal suspension of about 18 percent in water or as a fine suspension in oil, and then diluted with dis­tilled or de-mineralized water. Complete homogenization is of the utmost impor­tance and the lubricant should be thoroughly mixed before use. This lubri­cant is sometimes used for the lubrica­tion of extrusion dies.

Separation of fluids or solids that results from a difference in weight.

An inverted capstan that allows the coils of drawn wire to be deposited by gravity onto an independent receiver.

The draining of coolant from wiredrawing machines so that it will flow by gravity into a holding tank.

Designation for Galvanized Rigid Conduit.

A term used to describe a soap paste used in cold drawing to obtain a clean bright finish. This paste may or may not contain petroleum products, even though the term suggests that it does.

A wire rod that is in the hot-rolled condition prior to any further work being applied to it.

A form of high temperature attack on stainless steel, nickel chromium alloys and nickel chromium alloys subjected to simultaneous oxidation and carburization. Basically, the attack occurs by first precipitating chromium as chromium carbide and then oxidizing the carbide particles.

See Vitriol.

The removal of metal from a surface by the application of an abrasive.

A rubber seal used to seal cable.

Slot or cavity in a connector, which bears directly on the cable. Also the depression in a crimping die, which holds the connector during crimping. A depression encircling the body of a roll into which the piece being rolled is forced. Also, a depression on a drum used for winding cables.

To connect to the earth or other large conducting body to serve as an earth thus making a complete electrical circuit. 2) A wire intended to be used for grounding (also called Grounding Conductor).

A pilot wire in portable cables to monitor the grounding circuit.

A conductor used in mining cables to monitor the continuity of the grounding circuit which causes the power conductors to be de-energized in the event that ground continuity is lost. Also called a ground-monitoring conductor. Used in types G-GC, SHD-GC and MPF-GC, and identified by yellow colored insulation.

A conductor in a transmission cable or line that is grounded.

See Fault, Ground.

A protective device that detects abnormal current flowing to ground and then interrupts the circuit.

The major insulation used between a winding and the magnetic core of other structural parts, usually at ground potential.

The generation of undesirable current flow within a ground conductor, owing to the circulation currents that originate from a second source of voltage, frequently as a result of connecting two separate grounds to a single circuit.
