Above-ground lines cost around $10 per 1-foot (0.30 m) and underground lines cost in the range of $20 to $40 per 1-foot (0.30 m). [10] In highly urbanized areas, the cost of underground transmission can be 10–14 times as expensive as overhead. [11] However, these calculations may neglect the cost of power interruptions.
Each phase wire provides around 230 V to loads connected between it and the neutral. Each of the phase wires carries 50 Hz alternating current which is 120° out of phase with the other two. Several slightly different voltage standards have been used in the past as well: 220Y380, 230Y400 and 240Y415, with plans for future "harmonization ...
It has cost and weight advantages over copper wires. Aluminum in power transmission and distribution applications is still the preferred wire material today. [3] In North American residential construction, aluminum wire was used for wiring entire houses for a short time from the 1960s to the mid-1970s during a period of high copper prices.
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 ...

The optimization problem is made more complex by additional factors such as varying annual load, varying cost of installation, and the discrete sizes of cable that are commonly made. [ 1 ] [ 10 ] Since a conductor is a flexible object with uniform weight per unit length, the shape of a conductor strung between two towers approximates that of a ...
