Thus a 1,000 foot (300 m) spool of diamond wire costs around $200 to manufacture and sells for around $1,250. Selling cost may vary because of wire grade and demand. Other diamond wire cutting can use shaped diamond rings threaded through cables. These larger cables are used to cut concrete and other large projects.
A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires. [1] Cable reels, which can also be termed as drums, have been used for many years to transport electric cables, fiber optic cables [ 2 ] and wire products.
A bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. [1] Bobbins are typically found in industrial textile machinery , [ 2 ] as well as in sewing machines , fishing reels , tape measures , film rolls , cassette tapes , within electronic and electrical equipment, and for various ...

For oilfield work, the wireline resides on the surface, wound around a large (3 to 10 feet in diameter) spool. Operators may use a portable spool (on the back of a special truck) or a permanent part of the drilling rig. A motor and drive train turn the spool and raise and lower the equipment into and out of the well – the winch.

Rolls-Royce chose the triple-spool system in 1965 as the simplest, lowest cost solution to the problem of obtaining lower fuel consumption and reduced noise levels at a constant power setting. Work on the RB211 as essentially a scaled-down RB207 began in 1966-7 with the first certificated engines being scheduled to be available by December 1970 ...
Rolls-Royce chose a three-spool configuration for their large civil turbofans (i.e. the RB211 and Trent families), where the booster stages of a boosted two-spool configuration are separated into an intermediate pressure (IP) spool, driven by its own turbine. The first three-spool engine was the earlier Rolls-Royce RB.203 Trent of 1967.
