Area of application for Ultraflexx® flexible busbars

The Ultraflexx® flexible busbars are highly flexible connectors made of flat copper mesh and reliably absorb vibrations and switching shocks.

The press-welded connections are press-welded over the entire connection cross-section (contrary to the generally available press technology) and can be machined like a solid end piece.

Ultraflexx® are ideal for flexible use of space and are the best alternative to prefabricated cables. Thanks to our different cross-sections, Ultraflexx® can be adapted to a wide range of equipment and used as connectors between various control cabinet modules and units.

Conductor material Ultraflexx®

  • Highly flexible flat braids made of Cu-ETP1 with best conductivity
  • Electrical conductivity 58 MS/m
  • Single wire diameter 0.15 mm
  • Cross-sections from 25 to 240 mm²
  • Length is defined as hole center distance
  • Lengths from 150 to 1000 mm, in 50 mm steps
  • Connections with press-welded connection ends.
  • The connection ends can be machined like a solid end piece.
  • They are vibration-resistant and allow the lowest contact resistances to pass through.
  • Lower power loss and smaller voltage drop.
  • No corrosion and thus no deterioration of the connection resistances over time.

Ultraflexx® insulation

Ultraflexx® flexible busbars are robustly insulated to withstand high operating voltages:

  • Halogen-free polyolefin tubing, black
  • Wall thickness 0.8 ±0.3 mm
    Operating temperatures -55° C to +125° C
  • Flame retardant according to UL 224 – VW 1
  • Operating voltage max. 1000 VAC – 1500 VDC
  • Dielectric strength 20kV/mm
  • Individual wall thicknesses or colours on request!
