Wireline truck rigged up to a drilling rig in Canada. In the oil and gas industry, the term wireline usually refers to the use of multi-conductor, single conductor or slickline cable, or "wireline", as a conveyance for the acquisition of subsurface petrophysical and geophysical data and the delivery of well construction services such as pipe recovery, perforating, plug setting and well ...
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.
The groove pattern is engineered to suit the rope's length, diameter and construction type. Spooling under tension In any multi-layer spooling application it is important that when the rope is first installed on the drum, it is done so under tension to avoid any slack on inner layers that can be crushed or nicked against the groove walls by ...
The three ropes are so tightly wound counter to the weave of the constituent ropes that the fibers are compressed and the individual weaves stressed, sealing out the water and resulting in a length of about 180 metres (100 fathoms), the UK traditional definition of cable length. Using a cable, the raising of the anchor, or any activity ...
The length of a sinusoidal wave is commonly expressed as an angle, in units of degrees (with 360° in a wavelength) or radians (with 2π radians in a wavelength). So alternately the electrical length can be expressed as an angle which is the phase shift of the wave between the ends of the conductor [1] [3] [5]
A cable in this usage cable is a thick rope or by transference a chain cable. [1] The OED gives quotations from c. 1400 onwards. A cable's length (often "cable length" or just "cable") is simply the standard length in which cables came, which by 1555 had settled to around 100 fathoms (600 ft; 180 m) or 1 ⁄ 10 nautical mile (0.19 km; 0.12 mi).

There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments. Although similar in process, drawing is different from extrusion , because in drawing the wire is pulled, rather than pushed, through the die.
During the design phase of the Oliver Hazard Perry class, the head of the Royal Corps of Naval Constructors, R.J. Daniels, was invited by an old friend, U.S. Chief of the Bureau of Ships, Adm Robert C Gooding, to advise upon the use of variable-pitch propellers in the class. During this conversation, Daniels warned Gooding against the use of ...
