What is Bare Copper Wire Used for
Bare copper wire is a type of electrical wire that does not have any coating or insulation on it, which means that it is entirely made of copper. This type of wire is commonly used in a wide range of electrical applications, including:
Grounding
Stranded copper wire for sale is often used as a grounding wire in electrical systems. The wire is connected to a grounding rod or plate, which helps to protect against electrical surges and lightning strikes.
Electrical wiring
Bare copper wire and stranded wire products are also used in electrical wiring applications where insulation is not required. For example, it can be used to connect two metal components together or as a component in a homemade electrical circuit.
Arts and crafts
Stranded wire product is a popular material for jewelry making and other arts and crafts projects. The wire can be easily shaped and formed into different designs, and its natural copper color provides a unique and attractive look.
Science experiments
Bare copper wire and stranded copper wire is commonly used in science experiments and demonstrations, such as creating electromagnets or simple circuits.
