COPPER WIRES

Copper wire is typically defined as consisting of a single conductor for electrical signals, differentiated from a copper cable wherein multiple copper wires are grouped into a common jacket.

The many types of copper wire share a common function — the conduction of electricity with minimal resistance which causes voltage drops and energy dissipation in the form of heat. In fact, copper has been used since the 1820s when the first technology requiring electrical conductivity was developed. No other metal can compete with its conductivity, plus copper wire requires less insulation and can be stretched more effectively than other metals.
