Busbar Insulation

We have an extensive portfolio when it comes to busbar insulation, which covers a broad area of application – both films for less sensitive standard applications and high-performance versions for the highest demands for high temperature classes. Our standard portfolio includes busbar insulation with a nominal thickness of 125 µm and 185 µm for temperature classes A (105°C) and B (130°C).

Depending on the temperature class and the requirements, the result can be special combinations of polymer films (dielectrics) and single-sided or double-sided adhesive systems. The single-sided or double-sided adhesive system allows rapid further processing and lasting adhesion. In order to guarantee optimal technical properties such as rigidity and dialectric strength, we only work with selected, low-shrinkage polymer films:

PET
Polyimide
Nomex®
Tedlar®

Our electrical insulation films fulfil all of the requirements of UL61800-5-1. This means that there is a cost- and time-saving route to UL508C certification of your end products available to you.
