Bunched Wires

Both tinned and bare bunched wires are produced at our advanced technology bunching lines up to 16 mm² cross-sectional area.

  • Bunched wires are produced through compressing and stranding fine wires of a certain number and diameter.
  • Bunched wires are more flexible and easier to use than a solid conductor that has the same cross-sectional area.
  • In order to obtain more flexible wires with same cross-sectional area, the diameter of the  single wires are drawn down and bunched together.
  • Bunched wires are categorized based on their geometric structures that are determined pursuant to their area of use, their lay lengths and lay directions.

Types of Stranding

Regular Bunched Wires

  • Regular bunched wires are obtained by stranding one or more multi wire bundles with a certain lay length.
  • There is no geometric structure in the wires of the single copper wires.
  • Concentric bunched wires have more smooth surface comparing to regular bunched wires.

Concentric Bunched Wires

  • Concentric bunched wires are the most preferred form of stranding in cables and conductors.
  • In this type of stranding, there is a wire at the center and one or more layers surrounding this wire.
  • The number of wires of each layer is 6 more than the wires present in an inner layer.
  • A more rounded surface is obtained than regular bunched wires

Rope Bunched Wires

  • It is a mixture of regular bunched and concentric bunched wires.
  • Ropes can be produced in two different ways depending on whether the lower layers are  regular bunched or concentric bunched.
  • There are three types of rope stranding, which structurally differ.
