Copper Wire Rope Lay

Copper wire is well known for its ability to conduct electricity. Bare Wire Division has three main types of copper wire rope lay available, each with unique attributes:

  • Ultra-fine wire rope lay. Ultra-fine copper wire rope lay is a conductor made up of separate wire strands twisted together in rope fashion.
  • Rope lay bunched cable. Copper wire cable is constructed as a random gathering of single-strand copper wires twisted together with the same lay direction and length, without a particular pattern.
  • Rope lay concentric cable. Concentric cables have a geometric pattern to the design, with helically laid wires surrounding a centralized wire.

Copper wire rope lay has a flexible yet durable design that facilitates installation. For added resistance to bending stress, smaller gauge sizes are an ideal choice, as are conductors with fine stranding for increasing the amount of bending cycles that the rope lay can handle. Some common applications for copper rope include:

  • Electrical applications
  • Grounding straps
  • Shunts
  • Uninsulated, vibration-resistant electrical connections

Bunched Copper Wire

With a design much like rope lay bunched cables, durable bunched copper wires are constructed of individual strands that are placed indiscriminately and twisted in the same direction with the same lay length, with no particular pattern. Bunched wires aren’t as flexible as wire rope lay, but they are still quite malleable. They also have a greater packing density as compared to cabled conductors. Other beneficial properties of bunched wires include their ductility and corrosion resistance, for varied applications in:

  • Connectors
  • Data networks
  • Electrical appliances
  • Grounding devices for circuits and machinery
  • Radio transmission equipment
  • Security cameras
  • Space shuttles
  • Transmission and distribution lines related to aerial power

Concentric and Unilay Copper Wire

Concentric wires have a central wire at their core that is surrounded by helically laid wires in a geometrically patterned single- or multi-layer construction. Unilay copper wires are a form of concentric strands and possess a similar design, but the wires are of the same lay direction and length. Both concentric/unilay and large concentric/unilay copper wire are available from the Bare Wire Division. Their form gives this flexible copper wire an even, smooth surface with consistent elongation in the single wires. Concentric and unilay copper wires are also highly conductive, with applications in:

  • Audio and speaker wiring
  • Naval- and military-based tasks
  • Robotics
  • Vehicle wire harnesses

Bare Single End Copper Wire

Copper wire classifies as bare single end wire when a single strand of copper is drawn from a rod at a particular length. This product can come on bobbins of parallel-wound wires in spools of anywhere from two to 22 wires. We offer bare single end wire as well as bare single end wire on a bobbin for shielding. As a copper product, bare single end copper wire is conductive, as well as malleable and solderable with good ductility. It also offers long-term durability to ensure it will last in applications such as:

  • Braiding
  • Building wire conductors
  • Cables for telecommunications
  • Grounding wires
