nouvelles de l'entreprise How Does a Copper Wire Bunching Machine Compare to a Stranding Machine ?

In the world of cable manufacturing, both bunching and stranding machines are used to combine multiple fine wires into a single conductor. They perform a similar function, but the final product and the method are quite different. This leads to a common question: what are the key differences between a Copper Wire Bunching Machine and a stranding machine, and when would you choose one over the other?

The primary difference lies in the method of twisting and the resulting conductor geometry.

A Copper Wire Bunching Machine twists all individual wires together simultaneously without a central core. The resulting conductor is known as a bunch. The key characteristics of a bunched conductor are:

High Flexibility: All wires are twisted together, making the final conductor very pliable and easy to bend.

Rounder Shape: The bunching process creates a naturally round and uniform conductor.

Fewer Wires: Bunching is typically used for conductors with a relatively low number of wires (e.g., up to 100 strands).

A stranding machine, on the other hand, strands wires around a central core. The wires are twisted in concentric layers around this central wire. This process is used to create a conductor known as a strand. Key characteristics of a stranded conductor are:

Higher Strength: The layered structure gives the conductor greater mechanical strength.

Larger Conductor: Stranding is typically used for very large conductors with a high number of wires.

Less Flexibility: A stranded conductor is generally less flexible than a bunched conductor of a similar size.

Therefore, you would choose a Copper Wire Bunching Machine for applications where flexibility is the most important factor, such as in automotive cables, speaker wire, and appliance cords. You would choose a stranding machine for large power cables or overhead lines where high strength is the primary requirement.
