Highly flexible busbars - Conductor Material & Connections

EMS highly flexible Ultraflexx

Braided conductor material

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

  • Highly flexible flat fabric made of Cu-ETP1┬á
  • Single wire diameter 0.15 mm
  • Electrical conductance 58 MS/m

SPS Standard Produkte Schwanenmühle GmbH offers standard Ultraflexx® from stock. Please visit our SPS website or our SPS online store!

Ultraflexx® connections

The press-welded connections are (contrary to the generally available press technology) press-welded over the entire connection cross-section:

  • 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 dissipation and smaller voltage drop
  • No corrosion and thus no deterioration of the terminal resistances over time


EMS Elektro Metall Schwanenm├╝hle GmbH is a certified welding company according to DIN EN ISO 3834 T3.

Approval of Standard-Ultraflexx® from SPS
UL 508

CE, REACH, ICE 61439-1

Determined according to IEC or UL standard

Ultraflexx® current carrying capacity of standard dimensions

ULFX [cross section mm┬▓] –
[LA = hole spacing length] –
[D1 / D2 = hole diameter]

Lengths [LA] from 150-1000 mm in 50 mm steps. The length is defined as hole center distance.

For Ultraflexx® highly flexible busbars, the current carrying capacity is determined according to the following table based on IEC or UL standards:
