It is when people go into phone lines, city light boxes, empty buildings and strip them of the copper wire . They sell it to recyclers for the money so they can buy meth. It causes whole streets and neighborhoods to go dark costing city governments millions of dollars,businesses have to repair air conditioning and heating systems. This is costing taxpayers millions.
Copper is a very conductive metal and also ductile.
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
Copper cable doesn't conduct as well as Aluminum , but for most applications, Copper doesn't heat up as quickly as Aluminum, and is stronger in tensile strength. Also when using Aluminum cable you need to use an oxide to help conduct as Aluminum will work loose from locks in time.
One of the major functions of copper cable is to conduct electricity. It is also quite malleable and can be moulded to many forms. You can also make it very thin for more effective wires.
Copper can be found in BC and Alberta
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
A copper cable transports electrical signals. An optical cable transports light signals.
It depends on the length of th cable and the diameter of the copper cable used.

I know two kind of machines for copper recycling. One is cable granulator which is used for making copper core into small granules by grinding cable and separating PVC. This is a ideal machine for miscellaneous cable. The other is copper wire stripper which is to strip the PVC cover and you get the entire copper core. This is widely used in various copper wire various diameters.
Fiber optic cable is constructed out of glass or plastic, and uses light pulses to transmit data. Copper cable is made out of copper material (not glass or plastic) and uses electrical voltages to transmit signals.
Copper cable with PVC insulation
Copper xlpe armoured cable
Coaxial cable, STP cable, UTP cable
according to CompTIA A+ guide to hardware Lab Manual: "Any visible copper is an indication you need a new cable." -jazzmarazz13
Cable is 100% copper, and connectors are Gold Plated. No one uses silver or gold for the cable part.
Yry means copper round armoured cable
