Profile tubes made of cotton-fabric type Krütex 100-P or 102-P are mainly used in the low voltage sector as insulators with high mechanic values. These profile tubes can have a quadratic, rectangular, oval or hexagonal cross-section depending on the available pressing tools. Besides that we can also cut out squares in L- and U-shape of the profile tubes. Out of rods there mainly produced all kinds of machined parts.
Structure: Profile tubes made of Krütex consist of with phenolic resin impregnated cotton-fabric-layers. They are parallel winded on winding machines and then get exactly shaped and at the same time hardened in hydraulic presses and heated presstools. There these layers get indissoluble. The finished tubes then get worked as the customer wishes. Rods are coreless winded and then get compressed in hydraulic presses.
We can produce the following Krütex ®-types
