Copper flexible busbarsflexi2

We are expanding our range by flexible busbars, which serves there, where is not possible to use the standard busbars(because of bending, torsion, etc.).

Lower weight and volume

Due to used material and manufacturing process is possible to shape the busbars with minimal bend radius. Compared to cable recommended for the same current load has the flexible busbar 40% less cross-section. 

Appearance, efectiveness and time-saving installation

Flexibility of busbar material and its maximal ductility does not limit you by conception of joint. The flexible busbar maintains the selected shape and prevents unwanted distortion and unwanted memmory effect.

Safety and emphasis on reliable solution

Key featuress:

  • easy shaping reduces the number of connections
  • alimination of cable lugs
  • fewer joints in draft reduces the potential risks
  • manufacturing process ensures a constant thickness of insulation over the entire surface
  • output control of each busbar by dielectric strength test at 20,000 V.

Technical Specifications

  • Conductor of electrolytic copper
  • Insulation of high-endurance vinyl compound (2 mm ± 0.2 mm)
  • Bend 370%
  • Max. Operating Temperature 105 ° C
  • The thickness of each slat 1 mm
  • Self-extinguishing UL 94 VO
  • Dielectric strength 13kV/mm
  • Operating voltage <3500V

Calculating of potential busbar load with respect to the internal temperature

Temperature rise of conductor:

ΔT(°C) = T2 - T1

T2 max = 105 °C

Explanations

N = number of busbar straps

A = width of busbar straps

B = thisckness of one busbar strap

2 layers = current coefficient by using of 2 busbars

3 layers = current coefficient by using of 3 busbars
