A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power . Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed.
In both those instances the white wire should be identified as being hot, usually with black tape inside junction boxes. The neutral wire is identified by gray or white insulated wire, perhaps using stripes or markings. With lamp cord wire the ribbed wire is the neutral, and the smooth wire is the hot. NEC 2008 400.22(f) allows surface marking ...
A wire or cable has a voltage (to neutral) rating and a maximum conductor surface temperature rating. The amount of current a cable or wire can safely carry depends on the installation conditions. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission.
In commerce, the sizes of wire are estimated by devices, also called gauges, which consist of plates of circular or oblong form having notches of different widths around their edges to receive wire and sheet metals of different thicknesses. Each notch is stamped with a number, and the wire or sheet, which just fits a given notch, is stated to ...
In the Dandenong Ranges area Victoria 2014. Medium voltage (11-22 kV) ABC is being replaced with underground cable due to high failure rates of HV ABC, with life expectancy of just 10 years, when original life was expected to be approx 30 years. Due to degraded cable, cost of repairs & maintenance and bushfire risk.
Most carriers have a rectangular cross section, inside which the cables lie. Cross bars along the length of the carrier can be opened from the outside, so that cables can be easily inserted and plugs connected. Internal separators in the carrier separate the cables. Cables can also be held in place with an integrated strain relief.
