Insulated Flexible Aluminum Bus Bar Sizes

Flexible aluminum bus bars are made of aluminum foil thickness from 0.1 to 1mm. They are produced by process of welding, stamping, plating, forming, insulation and so on. The insulation can be pvc dipping and PE heat shrink tubing. Because of it's feature of good conductivity, flexible, easy to install and light weight, flexible busbars are widely used in electric vehicle and electrical suppression in low voltage applications. The primary differences between aluminum and copper bus bar is that aluminum is more cost-effective and lighter weight.Models and sizes can be customized.


RHI manufacture and supply wide range of custom aluminum busbars. 

Strength:quality aluminum has plenty of tensile strength to withstand thermal expansion strain.Depending on the alloying agents employed, the strength of aluminum itself can range from dead soft to mild steel.

Ampacity: Contingent on busbar size, aluminum busbar can handle currents up to 4000A, which is more than sufficient for many applications.

Conductivity:Aluminum busbar conductivity is dependent on the alloy and temper. Pure aluminum conductivity is approximately 65.0% of IACS.

Resistance:High quality, high strength aluminum can have mechanical resistance up to 530 Newton/mm2. Aluminum is fatigue resistant and corrosion resistant. Aluminum also offers easy corrosion removal with simple stripping.

Weight: Aluminum can be as much as 70% lighter than copper.

Aluminum Bus Bar Advantages:

  • High Corrosion Resistance

  • Good Conductivity

  • Great Heat Exchange

  • Efficient Thermal Dissipation

  • Lightweight

  • Cost Effective
