Kobbertråd

Kobbertråd is the Danish word for copper wire. Copper wire is a fundamental component in numerous electrical and electronic applications due to copper's excellent conductivity. It is commonly used for transmitting electrical power and signals. The purity of the copper is a critical factor in its conductivity; higher purity generally leads to better performance.

Copper wire is manufactured in various forms, including solid, stranded, and braided. Solid copper wire is rigid and typically used for fixed installations like in buildings. Stranded wire consists of multiple thin strands twisted together, offering greater flexibility and resistance to breakage, making it suitable for applications involving movement, such as in appliances and automotive wiring. Braided wire, made of many fine strands woven together, provides maximum flexibility.

The insulation surrounding copper wire is also important, protecting it from damage, preventing short circuits, and ensuring safety. Common insulating materials include PVC, rubber, and various polymers. The gauge of the wire, which refers to its thickness, determines its current-carrying capacity and resistance. Thicker wires have lower resistance and can carry more current. Kobbertråd plays a vital role in the functioning of everyday devices and infrastructure.
