Flerledertråder

Flerledertråder, also known as stranded wire, refers to an electrical conductor made up of multiple smaller strands of wire twisted or bundled together. This construction contrasts with solid wire, which consists of a single, solid core. The primary advantage of flerledertråder is its flexibility. The individual strands can move independently, allowing the wire to bend repeatedly without breaking. This makes it ideal for applications where movement or vibration is expected, such as in appliance cords, automotive wiring, and robotics.

The construction of flerledertråder can vary in the number, gauge, and material of the individual strands. Common materials include copper and aluminum. The total cross-sectional area of the strands determines the wire's current-carrying capacity, often expressed in American Wire Gauge (AWG) or square millimeters. While offering superior flexibility, flerledertråder can be slightly more expensive and complex to terminate than solid wire due to the need for specialized connectors or careful preparation to ensure all strands make good contact. In some high-frequency applications, the skin effect can influence current distribution, with the current tending to flow along the surface of each individual strand in a flerledertråd.
