Aluminium is not used for water pipes. It's not as elastic as Copper.
Because aluminium is less expensive than copper, it is sometimes used for electrical wiring, but, because it corrodes much more easily than copper, much more care has to be taken a) to protect it from the atmosphere and b) to make connections that will be remain reliable over a long period of time. Overall, aluminium wire is not as easy to install so, for general purposes, copper wire is better.
The pipes are PVC electrical conduits.
Conduit fitting is used on metal pipes that house electrical wires. These fittings are not only to connect the various pieces together, but to keep a relatively water tight seal to the wires.
Copper is frequently used for electrical wires. Aluminium is cheaper but breakable.
It is known as the service stack.
water/liquid
yes they do they use for lots of thing like pipes wires electrical cords
Steel is not used as an electrical conductor because, although it is a conductor, it's not a very good conductor -as is copper and aluminium, for example. A steel-wire core is used, however, to reinforce aluminium conductors on transmission tower lines
What is the basic frame work of roads electric wires water and gas pipes fiber optic cables etc.?
Aluminum is used in electrical wires as it is a good conductor, is lightweight and inexpensive (as compared to it's closest competitor copper). Most power distribution lines, especially overhead ones, are aluminum.
Aluminum wires are insulated.
As long as the wires are fed to the panel from above.
Copper coins (though are more an alloy than pure copper nowadays), copper pipes in plumbing, copper plus tin and other metals to produce bronze. There is also the copper used to produce electrical wiring. There is even aluminium wires clad (coated) in a thin layer of copper for electrical use. The list could go on...!
