Copper wire is an electrical conductor used in a variety of electrical applications. It can be found in homes, offices, factories and other industrial facilities. Conductors are made of single or stranded pure copper and are insulated with various materials such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyurethane (PUR) or polytetrafluoroethylene (PTFE) . This insulation prevents short circuits and the risk of electrical fires caused by arcing between wires in a circuit.
Copper wire has a high conductivity (about 90% that of silver), which makes it an ideal material for electronics. Copper also has a low electrical resistance compared to other metals such as aluminum or steel, making it ideal for high-power applications such as power lines and low-voltage wiring.
