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 ...
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.
Cable and strand is available in galvanized carbon steel, type 304 stainless steel, or the highly corrosion resistant, type 316 stainless steel (best for coastal areas). The most common cable construction is 1x19 type construction strand, which is 19 cables twisted in a single bundle, whereas for example, 7x7 would be 7 cable bundles of 7 ...
To 15-7Φ5, for example, 5 said a single diameter 5.0mm of steel, 7Φ5 said seven of the steel wire to form a strand, and 15 that the diameter of each strand of 15mm, the total meaning is "one The beam consists of 7 strands of diameter 15 mm (each having a total diameter of about 15.24 mm, a dimensional deviation +0.40 -0.20; a diameter of ...
Lengths up to 16 feet (4.9 m) are common; the most common is 8 feet (2.4 m). Common thicknesses are 1 ⁄ 2 and 5 ⁄ 8 inch (13 and 16 mm); thicknesses of 1 ⁄ 4, 3 ⁄ 8, 3 ⁄ 4, and 1 inch (6, 10, 19, and 25 mm) are used in specific applications. In many parts of Canada, drywall is commonly referred to as Gyproc.
In electrical power distribution, armoured cable usually means steel wire armoured cable (SWA) which is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.
No. 1 is 0.30 in. (300 thou), and the smallest, No. 50, is 0.001 in. (1 thou or 25.4 µm). The system as a whole approximates an exponential curve , plotting diameter against gauge-number (each size is a approximately a constant multiple of the previous size).
For vertical applications the cable may include armor wires on top of the jacket, steel or Kevlar. The armor wires are attached to supporting plates periodically to help support the weight of the cable. A supporting plate may be included on each floor of the building, tower, or structure. This cable would be called an armored riser cable.
