2. Aluminum building wiring - Wikipedia

   en.wikipedia.org/wiki/Aluminum_building_wiring

   The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...

3. Service drop - Wikipedia

   en.wikipedia.org/wiki/Service_drop

   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 ...

4. Armoured cable - Wikipedia

   en.wikipedia.org/wiki/Armoured_cable

   Armour: Steel wire armour provides mechanical protection, which means the cable can withstand higher stresses, be buried directly and used in external or underground projects. [4] The armouring is normally connected to earth and can sometimes be used as the circuit protective conductor ("earth wire") for the equipment supplied by cable.

6. Aluminium-conductor steel-reinforced cable - Wikipedia

   en.wikipedia.org/wiki/Aluminium-conductor_steel...

   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.

7. Underground power line - Wikipedia

   en.wikipedia.org/wiki/Underground_power_line

   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.
