Copper cable is a type of electrical wire made primarily from copper, a highly conductive metal. It is widely used for transmitting electricity and data due to its excellent conductivity and durability. Copper cables come in various forms, including twisted pair cables for telecommunications and coaxial cables for cable television. These cables are essential in many applications, from residential wiring to industrial machinery. They can carry both low and high voltage, making them versatile for different uses. Additionally, copper cables are often preferred over alternatives like fiber optic cables in certain situations due to their cost-effectiveness and ease of installation.
