Busbar Insulation

AKABUS FastPress is the basis for reliable power distribution

Whether it’s a vehicle with a conventional combustion engine or a modern electric drive, an MRI scanner or a high-performance IT server, as diverse as these applications may be, they all have one thing in common: laminated busbars are used to ensure efficient and space-saving power distribution. Reliable insulation of the local power distribution plays a central role here. This is precisely where our AKABUS FastPress product comes in, as we are your experienced specialist in materials for electrical insulation.

Maximum efficiency for the production of busbar insulation

With the AKABUS FastPress product range, Krempel offers a solution specifically optimised for industrial busbar insulation. The materials enable short-cycle pressing with cycle times of no more than 10 minutes, and in many applications even less. This is made possible by an optimised adhesive formulation specifically designed for fast production processes. Furthermore, AKABUS FastPress is supplied without a release film, which significantly simplifies further processing.

Your benefits at a glance:

Akabus 2.0 Folienaufbau
  • Short cycle times
    Short-cycle pressing with a maximum pressing time of 10 minutes, and in some cases even less – ideal for efficient series production.
  • New adhesive formulation
    Optimised for fast and reliable processing in industrial production processes.
  • Linerless technology
    AKABUS FastPress is supplied without a release liner. The adhesive is tack-free, making the material particularly easy to handle.
  • Easy processing for roll goods
    The linerless design eliminates the need to remove release liners. This reduces the number of process steps and makes processing significantly easier for the customer.

Polymer films for maximum safety and processing speed

Depending on the temperature class and requirements, specific combinations of polymer films (dielectrics) and single-sided or double-sided adhesive systems are used. The single-sided or double-sided adhesive system enables rapid further processing and permanent adhesion. To ensure optimum technical properties, such as stiffness and dielectric strength, we use only selected, low-shrinkage polymer films:

  • PET
  • Polyimide
  • Nomex®
  • Tedlar®

Our electrical insulation films meet all the requirements of UL61800-5-1. This provides you with a cost- and time-saving route to certifying your end products to UL508C.

Our standard portfolio

For busbar insulation, we offer a comprehensive range with AKABUS FastPress that covers a wide range of applications, including films for less sensitive standard applications as well as high-performance versions for the most demanding requirements in high temperature classes. In our standard portfolio, we offer busbar insulation with nominal thicknesses of 125µm and 185µm for temperature classes A (105°C) and B (130°C).
