Assembly of several conductive wires, usually twisted or braided.

A tube used to protect electrical wiring. A channel for holding and protecting conductors and cables made of metal or an insulating material, usually circular in cross section like a pipe. Common varieties of conduit are EMT (electrical metallic tubing) and rigid conduit.

Amount of available across-sectional area occupied by wires inside a conduit.

A wet-drawing, slip type of machine which uses capstans, also referred to as cones, mounted on a common shaft with each succeeding capstan larger than the preceding one to compensate for wire elongation. Shaped as the name implies, cones perform a wire routing function within the machine, pulling the wire through the drawing die. The number of cones and their orientation depends upon a number of factors, including reduction of area, slip and size of wire.

The geometric pattern that cables will take in a conduit when the cables are pulled in parallel and the ratio of the conduit ID to the 1/C cable OD is less than 2.5.

The geometric pattern that cables will take in a conduit when the cables are triplexed or are pulled in parallel with the ratio of the conduit ID to the 1/C cable OD less than 2.5.

A written confirmation of an order given verbally.

A metal working process that uses the friction developed between a feedstock and the groove of a rotating wheel for the continuous extrusion of a range of nonferrous materials. The feedstock, which is usually in the form of rod or continuously cast bar, is drawn into the chamber formed between a groove machined in the rotating wheel and a closely fitting shoe. The passage is obstructed by an abutment supported by the shoe and the feedstock is prevented from continuing its progress around the circumference of the wheel. The frictional forces that develop between the material in the groove, the shoe and the abutment cause the feedstock to increase in temperature until the material develops enough plasticity to extrude through a die supported in the shoe.

Having a tapered round shape.

A spring of conical shape, the smaller coils of which come down inside the larger coils when the spring is compressed, providing a stronger spring for applications where there is a restricted space depth.

A device providing mechanical cable terminations.

That part of a circuit that has negligible impedance and which joins components or devices.

Interconnection of three electrical equipment windings in triangular fashion.

Interconnection of three electrical windings in star fashion.

A device used to physically and electrically connect two or more conductors. Also used to physically connect cable to equipment.

Used to make connections between cable and electrical equipment, machines, panels, bulkheads, printed circuits, electronic equipment and any other cable. There are many different shapes and designs, but one half of the connector must accept a round or flat cable. A fixed connector is used for attachment to a rigid surface, while a free connector mates with the wire or cable.

Amount of power reflected from the connector to connector interface, typically expressed in decibels.

A connector applied using pressure to form a cold weld between the conductor and the connector.

Used to join two different size conductors.

A type of power system in which the same amount of current flows through each piece of equipment, used for simplicity in street lighting circuits.
