Round strands, ropes & braids: Flat copper conductors KFL

Braided, flat rolled copper strip according to DIN 46444 and 72333.


Applications

  • Earthing straps
  • Busbars
  • Connectors

Particular benefits for our customers

  • Very good flexibility depending on construction
  • Adjustable degree of compaction, with cross-section remaining unchanged
  • Delivered by the meter or in fixed lengths (copper cutting parts KST)

    Manufacturing range

    • Materials: Cu-ETP1 and Cu-OF1
      Defined cross sections made of stainless steel and aluminium upon request
    • Coating: bare, tin-plated, nickel-plated and silver-plated
    • Variations: soft annealed
    • Single wire diameter: ranging from Ø 0.05 mm to Ø 0.16 mm (∅ 0.20 mm upon request)
    • Nominal cross section: ranging from 0.09 to 240 mm²
      Nominal cross section from 1.5 mm² to 70 mm² with single wire ∅ 0.05 mm upon request
    • Flat copper conductors with straight edges upon request

    The flexibility of our fabric tapes is determined by their design. The higher the number and the smaller the diameter of the individual wires, the more flexible the finished product will be.

    Thus, it is possible for all flat copper conductors to be precisely geared towards the desired application.

    Table of current loads

    Below you can select your appropriate cross-section as a function of the current load (determined at a room temperature of 35 °C and the maximum temperature of the conductor, viz. 70 °C).

    Due to other factors usually playing a role as well, the values indicated below are to be seen as a non-binding recommendation.
