Aluminum conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium , chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.

It is known as SWA BS 5467 Cable and it has a voltage rating of 600/1000 V. [7] SWA cable can be referred to more generally as mains cable, armoured cable, power cable and booklet armoured cable. The name power cable, however, applies to a wide range of cables including 6381Y, NYCY, NYY-J and 6491X Cable.
Superscreened cables for nuclear use are defined in IEC 96-4-1, 1990, however as there have been long gaps in the construction of nuclear power stations in Europe, many existing installations are using superscreened cables to the UK standard AESS(TRG) 71181 [16] which is referenced in IEC 61917.
Galvanized rigid conduit (GRC) is galvanized steel tubing, with a tubing wall that is thick enough to allow it to be threaded. Its common applications are in commercial and industrial construction. [1] It is designed to protect wire and connectors. Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may ...
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). The weight per unit length diminishes by an average of approximately 20% at each step.
The galvanising bath contains slightly over 0.1% aluminium, added to form a layer bonding between the iron and coated zinc. [ 2 ] [ 3 ] Annealing temperatures are around 500 to 565 °C. [ 2 ] Pre-1990 annealing lines used gas-fired heating; post-1990s the use of induction furnaces became common.
