Rézvezet

Rézvezet is a term originating from Hungarian that translates to "copper wire." It refers to a conductor made of copper, which is widely used in electrical wiring and other applications due to its excellent electrical conductivity and malleability. Copper is a highly efficient material for transmitting electrical current, making it the preferred choice for most electrical systems, from household wiring to high-voltage power lines. Its resistance to corrosion also contributes to its longevity and reliability.

The use of copper wire dates back to the late 19th century, when its electrical properties were fully recognized and its production became more widespread. Before copper, other metals like silver and gold, which are even more conductive, were too expensive for general use. Iron was also used but proved to be less efficient and more prone to corrosion. The development of practical methods for extracting and refining copper made it an economically viable and technically superior option.

Rézvezet can be found in various forms, including solid-core wires, stranded wires, and cables. Solid-core wires are typically used in applications where the wire is not expected to move frequently, such as in-wall wiring. Stranded wires, composed of many thin strands of copper twisted together, offer greater flexibility and are commonly used in applications where movement is expected, like appliance cords or extension cords. The insulation surrounding the rézvezet protects against electrical shock and prevents short circuits. The specific gauge and type of rézvezet used depend on the electrical current it is intended to carry and the environmental conditions it will be subjected to.
