Copper
Before copper and plastic pipes became available people used to use lead, iron or steel to make water pipes. Nowadays main water supply pipes for fresh water coming into buildings are made of plastic and pipes within buildings - delivering water to sinks, baths, showers and toilets - are made either of copper or plastic. Within buildings, pipes which take away waste water - which are also called drainage pipes - are usually made of plastic. Outside buildings, modern drainage pipes are mostly made of plastic but older drain pipes may be made of glazed earthenware (which is baked clay) or iron.
Not only can it be used as a roof covering, it often has been - albeit an expensive one. Many domed buildings, like state capitols, have had their domes covered with copper sheeting, which then oxidizes over time to form a distinctive green patina.
In extremely high amperages it can(as it will be radiating energy), but most normal installations of DC will not affect ethernet copper cabling. AC will almost always due to its alternating states. I'm not 100% sure on this, but in my office (Telecom Provider Central Office) we run ethernet and DC copper close to each other, but with AC with put them in a different tray and run them in plastic electrical tubing to help shield.
depend on how much budget, you can do fiber and multiplexes , or just cooper , depend is for data or phone? how much is the traffic?, this is a too open question that is more related to the bugdet that anything.
der, electrocution?
copper cable
There are different types of gibabit Ethernet; the cabling can either be some kind of copper cable, usually UTP, or fiber optic.
Fiber optics carry vastly more information than ordinary cables, for a given thickness of cable.
Copper is preferable to aluminum and the size of wire should be the same or the next size down if copper is used.
Copper is a conductor, which means it conducts heat more quickly, hence heating up faster. The same reason is for why copper is used in electricity cabling.
Vertical Cabling - Runs between floor to floor. It is used for Core to Distribution (or Access) switch connectivity. Usually consists of fiber cables Horizontal Cabling - Runs on one floor. Runs from Distribution or Access switches to the end user. Usually copper.
It's Cheaper
Copper
This is copper's version of oxidisation. It occurs very visibly on buildings with copper trim on the roofs.
Any shielded copper cable or fiber optic cable.
