The influence of less glue mica tape on the insulation performance of the coil

There are two main aspects of the influence of less glue mica tape on the insulation performance of the coil: one is the content of glue, generally the less the better. The second is the performance of the adhesive itself. The adhesive used by a good mica tape manufacturer not only meets the adhesive properties of the mica tape, but also has a very low dielectric loss value at high temperatures, while ensuring good compatibility between the mica tape and the impregnating resin.

The low rubber mica tape has sufficient flexibility at room temperature, which is conducive to wrapping the coil, and at the same time has good air permeability and air permeability, which is conducive to the extraction of air and volatiles from the insulating layer and the penetration of resin during the VPI impregnation process. Ensure the overall performance of the coil.
