Spirally wound tubes and caps for electrical insulation
insulating caps
Flexible electrical insulating materials can be used for a variety of applications. From the flexible electrical insulating materials offered, polyimide film, Mylar and Nomex, Dr. Dietrich Müller GmbH insulating sleeves.
These foils are also processed as a laminate, resulting in two- or three-layer caps and sleeves.
4 different versions of the insulating sleeves
These spiral wound insulating tubes are offered in different versions:
The four different variants are
- the shrinking, one-sided closed insulating cap,
- the non-shrinking, one-sided closed insulating cap,
- the shrinking, open insulating tube as well as
- the non-shrinking, open insulating tube.
Caps, sleeves and hoses can also be made from the other technical films offered. In particular, closed caps made of thermally conductive polyimide film have already been realized.
In addition, the Dr. Dietrich Müller GmbH Insulating sleeves made of Tecfilm PEI TC 00421 in black. Sleeves made of Tecfilm PEI TC 00421 were made for optical purposes in cameras.
Insulating caps made from battery separator foil
the dr Dietrich Müller GmbH ready-to-use spiral-wound sleeves made from various battery separator foils.
Applications of the insulating sleeves
The spiral wound foils are generally used for the electrical insulation of wire connections and thermal sensors in electric motors, generators and transformers. The insulating sleeves usually protect the internal wire connection from mechanical stress. Another function is electrical insulation.
We provide an overview of our insulating hoses and glass fiber hoses in our article "Overview of insulating hoses and glass fiber hoses".
