Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...
High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.
V 3 Ga superconducting tape (10×0.14 mm cross section). A vanadium core is covered with 15 μm V 3 Ga layer, then 20 μm bronze (stabilizing layer) and 15 μm insulating layer. Critical current 180 A (19.2 tesla, 4.2 K), critical current density 20 kA/cm 2
A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure. They are used commonly for ship masts , radio masts , wind turbines , utility poles , and tents .
The 2.5 mm or sub-miniature sizes were similarly popularized on small portable electronics. They often appeared next to a 3.5 mm microphone jack for a remote control on-off switch on early portable tape recorders; the microphone provided with such machines had the on-off switch and used a two-pronged connector with both the 3.5 and 2.5 mm plugs.
The 1983 TOW 2 featured a larger 5.9 kg (13 lb) warhead with a 21.25 in (540 mm) extensible probe, improved resistance to jamming with a second, shorter wavelength xenon tracking beacon and optical encoders to randomly modulate the pulse frequency of both beacons and a motor that provided around 30% more thrust.
