Common questions

  1. What types of wire are available? Wire can be categorized according to its material composition (copper, aluminum, etc.), its function (electrical, mechanical, etc.), and its size (gauge or diameter).
  2. What is the difference between stranded and solid wire? Stranded wire is composed of many strands of metal, while solid wire is composed of a single piece of metal.
  3. What is the difference between single-core and multi-core wire? Single-core wire is composed of one insulated conductor, while multi-core wire is composed of multiple insulated conductors.
  4. What is the difference between insulated and uninsulated wire? Insulated wire is covered with a protective coating, while uninsulated wire is not.
  5. What are the different types of insulation? The most common types of insulation are PVC, Teflon, rubber, and polyethylene.
  6. What is the difference between flexible and rigid wire? Flexible wire is designed to bend easily, while rigid wire is designed to maintain its shape.
  7. How is wire rated? Wire is usually rated according to its conductor size, current-carrying capacity, and temperature range.
  8. How is wire sized? Wire is usually sized by its gauge or diameter, in either AWG (American Wire Gauge) or millimeters.
  9. What are the common applications for wire? Wire is commonly used in the automotive, construction, electrical, and telecommunications industries.


In 1940, two brothers in the Netherlands used wire to create a massive harp. The brothers, Gé and Jan Kalis, created the harp out of galvanized wire measuring nearly 1100 meters long, with a total of over 2600 strings. The harp was a success, and it was featured in a Dutch movie at the time. The brothers also used the harp to make music for a BBC broadcast. The harp was a unique instrument, and it is still remembered today as an example of the creative ways in which wire can be used. Source.
